Cold Caps For Migraine Relief Explained
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Your first instinct during a migraine is often the smartest one: find something cold and press it to your forehead or the back of your neck. We follow that primal move across 3,500 years of medical history and then zoom in on the modern science that finally explains why it can work. If you have ever wondered whether cold caps are “real” migraine treatment or just a comfort ritual, we break down the physiology behind the relief and what the research actually supports.
We dig into the core mechanisms of cold cap therapy for chronic headache and acute migraine relief, including vasoconstriction, peripheral nerve cooling, and the gate control theory of pain. We also talk about neurogenic inflammation and migraine related peptides like CGRP and substance P, plus the very real biology behind expectation based analgesia. From freezer gel caps to compression designs to Peltier effect thermoelectric wearables, we sort out what each tool is trying to do and what “modest but meaningful” results look like in practice.
Then we get honest about the limits. Cold is symptomatic and time bound, and once central sensitization and allodynia show up, the same cold and pressure that felt soothing can become unbearable. That’s the pivot point where we stop asking only how to mute pain signals and start asking why the signals won’t stop. We explore peripheral nerve compression as an underrecognized structural cause, how targeted nerve blocks help confirm trigger sites, and why peripheral nerve decompression surgery shows compelling outcomes in carefully selected patients, including sham controlled trial data.

Why We Reach For Cold
SPEAKER_01I want you to imagine just for a second that you have a pounding headache. Like not just a minor ache, but that really deep throbbing pain that makes you want to just crawl into a dark room and hide.
SPEAKER_00Oh, yeah. The kind where you can't even think straight.
SPEAKER_01Exactly. So, what is your very first sheer primal instinct? I mean, before you even reach for the medicine cabinet, you probably have this overwhelming urge to press something cold right against your forehead or, you know, the back of your neck.
SPEAKER_00Aaron Powell It's an incredibly intuitive response, really. Most of us don't even think about the mechanics of it. We just grab a bag of frozen peas or an ice pack or even cool washcloth. Your body is simply drawn to the cold when it's in that kind of pain.
SPEAKER_01Right. And that instinct, it's not just some modern convenience born out of having freezers in our kitchens. It's actually a biological pain relief behavior that has been documented for millennia.
SPEAKER_00Right. Our ancestors were doing the exact same thing to treat their migraines.
SPEAKER_01Yeah, which points to this fascinating continuity in human biology.
SPEAKER_00Aaron Powell It really does. Yeah. It tells us that sometimes, you know, our most universal ancient remedies hold very profound physiological secrets. Like when behavior persists across that many cultures and eras, it usually means there is a highly effective mechanism at play underneath the skin.
SPEAKER_01For sure.
A 3,500 Year Migraine Remedy
SPEAKER_01Welcome to today's deep dive. We are exploring a comprehensive clinical resource today from the migraine surgery specialty center out in Santa Barbara, California, and it's focused on cold cap therapy for chronic headache.
SPEAKER_00It's a great paper.
SPEAKER_01It is. But we aren't just looking at ice packs here. We are examining how a 3,500-year-old human instinct maps onto modern neuroscience. And well, where the limits of that physical therapy actually lie and what happens when temporary relief simply isn't enough to fix a structural problem.
SPEAKER_00It's a remarkable progression to follow. We are taking a journey from the very earliest historical records of medical care, straight into the mechanics of peripheral nerve anatomy, and ultimately to some highly advanced surgical interventions.
SPEAKER_01Okay, let's unpack this. Because starting with the history, I mean, understanding the timeline puts the modern technology into such a brilliant context.
SPEAKER_00It really does.
SPEAKER_01The clinical material actually traces this back to Egyptian medical papyri from around 1550 BCE. They were specifically describing the use of cold poultices for head pain.
SPEAKER_00Right. And the documentation only gets more precise from there. If you move into ancient Greece, Hippocrates was actively prescribing cool environments for patients suffering from what the texts very clearly describe as migrainous headaches.
SPEAKER_01Wow. Even Hippocrates.
SPEAKER_00Yeah. And then a few centuries later, in the second century CE, you have the Roman physician Eriteus of Cappadocia making some very specific clinical observations.
SPEAKER_01Right. He's the one who originally described hemicranial pain, right?
SPEAKER_00Exactly.
SPEAKER_01Meaning pain isolated to one side of the head, which is, you know, the classic diagnostic hallmark of a migraine today.
SPEAKER_00Precisely. Eritaus noted that his patients found significant relief not just in cool dark rooms, but with cold applications targeted specifically to the forehead and temples.
SPEAKER_01So he was actually targeting the pain.
SPEAKER_00Trevor Burrus He was essentially documenting the very first acute migraine protocol based entirely on physical temperature modulation.
SPEAKER_01Aaron Powell That is just it's basically early human biohacking.
SPEAKER_00It is.
SPEAKER_01You look at the medieval and Renaissance periods, and people are like pouring cold water over their heads or tying these cold-soaked linen cloths around their temples. But there's this one detail from the historical timeline that I found incredibly striking. Sufferers would literally hold cold river stones to their temples to stop the throbbing.
SPEAKER_00Just pulling rocks out of the water.
SPEAKER_01Yeah. They were just reaching into a stream and putting a freezing, smooth rock against their skin to intercept the pain.
SPEAKER_00It perfectly illustrates the human drive for a counter-stimulus. By the time we enter the 19th century, we see this ancient practice become thoroughly medicalized. Right. The mid-19th century brought about reliable commercial ice production. So suddenly, doctors had access to standardized cold therapy, and rubber ice bladders became an absolute staple in physicians' offices for treating what they termed sick headache.
SPEAKER_01Sick headache. So they were putting ice on their necks in the 19th century, hoping to like cool the blood, but were they actually accomplishing that?
SPEAKER_00Partially, yes. Early neurologists advocated putting ice specifically on the posterior neck, the occiput.
SPEAKER_01The back of the head.
SPEAKER_00Right. Their working theory was that they were physically cooling the blood as it entered the cranium through the carotid and vertebral vascular systems. They believed migraines were strictly a vascular issue, so they were trying to reduce the vascular engorgement by cooling the blood supply.
SPEAKER_01I mean, that is a bit imprecise by modern standards, right? Considering we now know migraine pathophysiology is highly neurological, not just, you know, dilated blood vessels.
SPEAKER_00Right, it's more complex than just blood flow.
SPEAKER_01But they were definitely pointing toward physical mechanisms that we still rely on today. By the early 20th century, ice packs were listed in medical texts right alongside heavy pharmacological interventions like ergotamine. And that eventually brings us to the 1980s and 90s, where we see the introduction of purpose-engineered cooling devices, like those gel-filled caps that actually conform to the skull.
SPEAKER_00Which brings up a critical juncture in our understanding. Ancient humans, and even those 19th-century doctors, knew that cold therapy worked. But modern neurobiology has finally allowed us to explain exactly how it works.
Vasoconstriction And Slower Pain Signals
SPEAKER_01We've finally peeked under the hood.
SPEAKER_00Exactly. We have moved from observing the outside of the head to understanding the complex cascade of biology happening underneath the skin.
SPEAKER_01And that cascade involves several overlapping physiological pathways. The most immediate one, which ties back to those 19th-century doctors, is vasoconstriction.
SPEAKER_00Right. Vasoconstriction is simply the physical narrowing of blood vessels. When you apply a cold cap to the scalp, those superficial blood vessels immediately constrict in response to the sudden temperature drop.
SPEAKER_01Because it's trying to conserve heat.
SPEAKER_00Yes. Now, while we know dilated blood vessels aren't the sole cause of a migraine, the pulsation of those vessels still matters. When extracranial vessels throb, they mechanically irritate the pain-sensitive nerve fibers that travel right alongside them.
SPEAKER_01Ah, I see.
SPEAKER_00So by constricting the vessel, you decrease that mechanical throbbing input.
SPEAKER_01Less throbbing equals less physical irritation of the nerve. That makes sense. But the temperature drop doesn't just act on the vascular system, right? It directly alters the nerves themselves through peripheral nerve cooling.
SPEAKER_00It does. And this is where the specific anatomy of the head becomes highly relevant. The human scalp is very richly innervated.
SPEAKER_01Lots of nerve endings.
SPEAKER_00Tons of them. In the frontal region, you have branches of the trigeminal nerve, specifically the supraorbital, subtle, and zygomaticotemporal nerves. Okay. And then in the back, you have the greater and lesser occipital nerves. Because these sensory nerves course very superficially just beneath the skin, a cold cap can literally drop their localized temperature.
SPEAKER_01And dropping the temperature physically slows down their neural conduction velocity? It's like putting a speed limit on a highway of pain signals, just delaying how fast those afferent signals can reach the brain's pain processing networks.
SPEAKER_00That's a great way to picture it.
SPEAKER_01But beyond just slowing the signals down, there is a mechanism of interception here that is incredibly elegant, and that involves the gate control theory.
SPEAKER_00Oh, yes. What's fascinating here is how Milzac and Wall's gate control theory, which was proposed back in 1965, beautifully explains the phenomenon of why a cold river stone actually stops a throb.
SPEAKER_01Right.
SPEAKER_00The theory suggests there's a neurological gate in the dorsal horn of your spinal cord that manages incoming sensory signals.
SPEAKER_01Like a bouncer at a club?
SPEAKER_00Pretty much. Your peripheral nervous system has different types of nerve fibers. You have A beta sensory fibers, which are large diameter and very fast conducting. They are responsible for transmitting non-painful sensory input, like you know, a sudden drop in temperature or light pressure.
SPEAKER_01While the actual pain signals are traveling on a different track entirely.
SPEAKER_00Correct. The no-susceptive or painful signals are transmitted by slower C fibers and A delta fibers. So when you apply an intensely cold cap to your head, you massively stimulate those fast A beta fibers.
SPEAKER_01And they just beat the pain signals to the gate.
SPEAKER_00Exactly. Because they conduct signals much faster, they race ahead to the spinal cord and essentially close the gate on the slower pain signals that are lagging behind. The non-painful thermal stimulus physically overrides the painful stimulus at the spinal level.
SPEAKER_01The cold is quite literally shutting the door on the pain.
SPEAKER_00It really is.
SPEAKER_01That structural explanation makes so much sense. We also see local metabolic effects specifically regarding murogenic inflammation, don't we? We do, yeah. Because during a migraine attack, the localized tissues experience a release of inflammatory proteins. Like the clinical literature frequently points to neuropeptides like CGRP calcitonin, gene-related peptide, and substance P. Right. And these proteins cause blood vessels to leak and surrounding tissues to swell, which obviously drives intense pain.
SPEAKER_00And introducing a profound cold stimulus slows down the local metabolic rate in those tissues. It attenuates the release of those inflammatory peptides, reduces venous congestion, and can even improve lymphatic drainage. You are actively reducing the tissue pressure around highly sensitized nerve structures.
SPEAKER_01Okay, but I want to push back on one of the mechanisms highlighted in the clinical data here.
SPEAKER_00Okay, sure.
SPEAKER_01Wait, if 25 to 40% of this is just placebo, because the literature consistently notes a placebo response rate of 25 to 40 percent in headache research. It does, yes. If we are seeing a 40% placebo response, how much of this physical relief is just psychological expectation? Like is the patient just imagining the relief because they put a fancy cap on?
SPEAKER_00That is a crucial distinction to make, actually, because the medical definition of placebo in this context does not mean imaginary.
SPEAKER_01Okay.
SPEAKER_00The ritual of active self-treatment, of taking control of the pain and expecting relief triggers a very real neurobiological substrate known as expectation-based analgesia.
SPEAKER_01Meaning what exactly?
SPEAKER_00Well, when you feel the psychological comfort of the cold cap, your brain responds by manufacturing and releasing endogenous opioids and serotonin.
SPEAKER_01Oh, wow. So it is your brain producing its own very real chemically measurable painkillers.
SPEAKER_00Exactly. It is therapeutically meaningful biology, not just a trick of the mind. So when you combine that endogenous opioid release with the vasoconstriction, the slowed nerve conduction, and closing the pain gate, you have a genuinely powerful multimodal
Cold Caps Today And What Works
SPEAKER_00toolkit.
SPEAKER_01Aaron Powell Which brings us to the actual hardware available today and what the clinical data tells us about its efficacy. The entry point for most patients is the standard gel pack cold cap.
SPEAKER_00Right, but ones you keep in the freezer.
SPEAKER_01Yeah. These are kept in the freezer, applied at the onset of an attack, and generally maintain a therapeutic temperature for maybe 20 to 30 minutes.
SPEAKER_00Aaron Powell And many modern iterations also integrate compression. These compression plus cold devices exploit two mechanisms simultaneously. The compression itself reduces that pulsatile blood flow we talk about, but it also adds a proprioceptive counter stimulus.
SPEAKER_01Meaning proprioception, like the body's spatial sense of pressure and position, is sending yet another non-painful signal to the brain to help crowd out the pain signals.
SPEAKER_00Right.
SPEAKER_01It is essentially giving the skull a tight cold hug.
SPEAKER_00Aaron Powell That's exactly what it feels like.
SPEAKER_01But from an anatomical perspective, the targeted occipital devices seem much more precise.
SPEAKER_00They definitely are. Targeted neck and occipital cooling devices are designed specifically for posterior pain. The greater, lesser, and third occipital nerves emerge at the back of the neck and course superficially through the tissue there.
SPEAKER_01So they're easy to reach.
SPEAKER_00Yeah. And designing a device to exclusively wrap and cool that specific anatomical junction is highly efficient.
SPEAKER_01It's like knowing exactly which circuit breaker to cool down rather than trying to freeze the entire house.
SPEAKER_00Yes.
SPEAKER_01And for patients who need sustained relief without constantly swapping out melting ice packs, there is wearable electric cooling technology that utilizes the Peltier effect.
SPEAKER_00Oh, the Peltier effect is a fascinating piece of thermoelectric engineering. Instead of relying on frozen water or gel, these devices use an electric current passed through two different conductive materials.
SPEAKER_01So no ice involved at all?
SPEAKER_00None. It absorbs heat from the side, touching your skin and releases it outward, essentially acting as a miniature battery-powered refrigerator for your targeted nerves. It allows for sustained, programmable cooling.
SPEAKER_01That is wild. But looking at the clinical data, we have to set realistic expectations here. Does all this engineered hardware actually stop migraine?
SPEAKER_00Well, the evidence base is positive, but it is modest. We are not looking at a universal cure here. The clinical data suggests a realistic goal of 30 to 50% pain reduction for patients experiencing mild to moderate attacks.
SPEAKER_01So for anyone who suffers from migraines, a 50% reduction in pain is deeply significant.
SPEAKER_00Oh, absolutely.
SPEAKER_01The resource highlights a highly referenced study by Sprouse Bloom and colleagues from 2013. They conducted a randomized controlled trial applying cold, heat, or control to the posterior neck.
SPEAKER_00And the results are pretty striking.
SPEAKER_01Yeah, the cold group showed a massive clinical advantage. 77% of them reported improvement at the 25-minute mark compared to just 33% of the control group.
SPEAKER_00And that efficacy is really reflected in patient behavior. An American Migraine Foundation survey of over 7,000 patients found that cold packs were by far the most frequently used non-pharmacological acute treatment.
SPEAKER_01Like nothing else comes close.
SPEAKER_00Right. Nearly 68% of patients utilize them, and over half found them clinically helpful.
SPEAKER_01And the clinical guidelines suggest they are best utilized early in the attack. Specifically, right in the prodrome phase, that early warning window where you might experience brain fog or visual auras before the full throbbing headache sets in.
SPEAKER_00Which is key for getting ahead of the pain cascade.
SPEAKER_01Yeah. It is also an absolutely vital tool for populations who cannot rely on medications, such as during pregnancy and lactation.
SPEAKER_00Or for patients who have strict medical contraindications to standard migraine drugs. Tryptans, for example, are a very common class of abortive migraine medications.
SPEAKER_01Very common.
SPEAKER_00But because their primary mechanism involves constricting blood vessels throughout the body, patients with cardiovascular disease or uncontrolled hypertension often cannot safely take them.
SPEAKER_01That makes sense.
SPEAKER_00So for those patients, localized cold therapy is one of their only safe, acute options.
SPEAKER_01But that forces us to look at the ceiling of this therapy, because if cold caps are this accessible, drug-free, and effective, why are there still millions of people suffering?
The Limits Of Symptom Relief
SPEAKER_00It's a fair question. The fundamental limitation of cold cap therapy is that it is strictly symptomatic and entirely acute.
SPEAKER_01It's a band-aid.
SPEAKER_00Exactly. It successfully modulates how pain signals are transmitted during a specific isolated attack. However, it does absolutely nothing to modify the underlying pathophysiology of the disease itself.
SPEAKER_01So it's not a preventative.
SPEAKER_00Right. Using a cold cap today will not prevent a migraine from occurring tomorrow, nor will it reduce your overall headache frequency over time.
SPEAKER_01Which creates a brutal reality for patients suffering from unremitting conditions. The clinical data points out that for patients with new daily persistent headache NDPH, where the pain is constant and unyielding, cold caps are practically useless as a primary strategy.
SPEAKER_00You just can't use them enough.
SPEAKER_01Right. You cannot physically wear a thermoelectric cooling device or a frozen gel cap 24 hours a day.
SPEAKER_00And doing so invites severe complications, prolonged exposure to extreme cold, risks thermal skin injury, tissue damage, and can even trigger paradoxical vasodilation.
SPEAKER_01Wait, what is paradoxical vasodilation?
SPEAKER_00It's where the blood vessels forcefully dilate to warm the freezing tissue, which can potentially worsen the trobbing.
SPEAKER_01Oh wow. So your body fights back against the cold. And even for episodic sufferers, if a migraine reaches a severe state involving intense nausea, extreme light sensitivity, and vomiting, the sheer logistics of getting out of bed to fetch a cold cap or tolerating its physical weight on the head becomes overwhelmingly distressing.
SPEAKER_00It's just too much sensory input.
SPEAKER_01And here's where it gets really interesting. Because there is a physiological barrier discussed in the literature known as the allodynea paradox.
SPEAKER_00Ah, yes. Allodynea is a highly specific neurological symptom where a patient perceives severe pain from a stimulus that should not normally be painful at all.
SPEAKER_01Like a light touch.
SPEAKER_00Right. Up to 70% of migrainers develop this during the course of an attack. It is a direct result of central sensitization.
SPEAKER_01Meaning the central nervous system gets so hyperreactive and wound up by the incoming pain signals that normal sensory input gets misrouted as agony.
SPEAKER_00Exactly.
SPEAKER_01Just brushing your hair or resting your head on a soft pillow feels excruciating.
SPEAKER_00Yes. And that creates the paradox with cold therapy. Early in the attack, before that central sensitization fully takes hold, the cold cap feels immensely soothing. The fast 8 beta fibers are successfully closing the pain gate.
SPEAKER_01Like we talked about earlier.
SPEAKER_00Right. But if the patient waits too long and central sensitization sets in, the physical weight of the cap and the intense thermal drop become painful stimuli themselves, the therapy feeds directly into the allodynea.
SPEAKER_01That is so unfair. The treatment becomes the torture.
SPEAKER_00It really is. And this raises an important question, and it actually represents a major pivot in modern headache medicine.
SPEAKER_01Okay.
When Nerve Compression Drives Headache
SPEAKER_00If a patient is dealing with chronic, unremitting daily pain and temporary physical modulation like cold therapy hits a wall, and if pharmacological modulations like tripcans or modern CGRP inhibitors also fail to break the cycle, what is the next logical step?
SPEAKER_01Right. What do you do?
SPEAKER_00What happens when we realize that the nerve irritation isn't just a temporary chemical event, but a permanent physical one?
SPEAKER_01So what does this all mean? It means we have to look beyond the pharmacy and beyond the ice pack. When all temporary chemical and thermal modulations fail, the clinical resource we are examining introduces a structural root cause, which is peripheral nerve compression.
SPEAKER_00Peripheral nerve compression is a remarkably underrecognized driver of highly refractory chronic headaches. We just discussed how the greater occipital nerve and the superorbital nerve course superficially through the head and neck.
SPEAKER_01Right, right under the skin.
SPEAKER_00Well, in a subset of patients, those specific sensory nerves become physically entrapped or compressed by the surrounding anatomy.
SPEAKER_01We are talking about tight fascial bands, heavy overlying muscle tissue, or even adjacent pulsing blood vessels bearing down directly on the nerve. It is essentially like a heavy boot stepping on a garden hose.
SPEAKER_00That's a perfect analogy.
SPEAKER_01That constant, unrelenting physical compression generates a persistent nociceptive pain signal. The nerve is constantly firing distress signals to the brain day in and day out, which over time drives that agonizing central sensitization we talked about.
SPEAKER_00And diagnostically, finding this compression is challenging. A compressed peripheral nerve presents with the exact same clinical symptom complex as a standard neurologically driven migraine.
SPEAKER_01And so it looks exactly the same.
SPEAKER_00The patient reports throbbing pain, light sensitivity, and nausea. And the structural compression is completely invisible on standard imaging unless a physician knows precisely how to look for it.
SPEAKER_01The clinical material actually details the diagnostic process, relying heavily on peripheral nerve blocks. Instead of imaging, the doctor uses a targeted injection of temporary local anesthesia to numb the specific suspected trigger sites.
SPEAKER_00It is a diagnostic test, not a treatment. Right. If injecting a small amount of numbing agent into the fascial tissue surrounding, say, the greater occipital nerve completely pauses a patient's unremitting headache for a few hours, it provides a massive piece of diagnostic evidence. Exactly.
SPEAKER_01The anatomy itself is the problem. And if those diagnostic blocks are successful, the patient is often an ideal candidate for peripheral nerve decompression surgery.
SPEAKER_00For a patient population that is largely felt abandoned by the traditional medical system, you know, after failing every medication and physical therapy available, identifying a tangible anatomical reason for their pain is often revolutionary.
SPEAKER_01I can imagine. The resource outlines the mechanics of the surgery. It is typically performed as an outpatient procedure under general anesthesia. The surgeon makes small strategic incisions to access the specific compressed nerve. And the crucial detail here is that they do not cut or sever the nerve itself.
SPEAKER_00No, the goal is always preservation.
SPEAKER_01Right. They carefully release the compressing structures. They might release a tight fascial band, remove a small piece of constricting muscle, or separate a pulsing blood vessel from the nerve sheath. They are simply giving the irritated nerve the physical room it needs to breathe and heal.
SPEAKER_00And the outcome data presented in the clinical literature is highly compelling. Looking at over two decades of prospective surgical trials, we see significant headache improvement in 68 to 92% of appropriately selected patients.
SPEAKER_01That is a huge success rate.
SPEAKER_00It really is. Even more profoundly, 30 to 57% of these highly refractory patients experience a complete durable elimination of their chronic headaches.
SPEAKER_01The clinical resource specifically highlights a landmark 2009 sham-controlled randomized trial, which is, you know, considered the gold standard of surgical evidence.
SPEAKER_00Yes, the sham surgery is key.
SPEAKER_01They essentially performed a placebo surgery on the control group to rule out psychological expectation.
SPEAKER_00Right, to make sure it wasn't just the placebo effect again. Exactly.
SPEAKER_01And the actual surgical decompression group demonstrated an 83.7% significant improvement rate compared to the sham control. It unequivocally validates that releasing the anatomical compression is a structural fix, not just the placebo effect of having an operation.
SPEAKER_00It represents a fundamentally different approach. It acknowledges that when the physical architecture of the body is driving the pain, chemical and thermal therapies will always eventually fall short.
SPEAKER_01It is incredible to step back and look at the vast scope of the journey we just explored today. I want to leave you with a thought to mull over. Consider how many of our most advanced, highly engineered medical interventions are simply modern ways of honoring our ancient intuitive biology.
SPEAKER_00That's a great point.
SPEAKER_01We started 3,500 years ago with our ancestors instinctively pulling freezing river stones out of the water to numb a screaming, throbbing nerve in their forehead. And today we utilize Pelletier effect, thermoelectric wearable cryotherapy, and microscopic peripheral nerve decompression surgery.
SPEAKER_00It's quite a leap.
SPEAKER_01The tools have evolved from river stones to precise surgical scalpels, but the ultimate human goal, soothing an irritated nerve, remains exactly the same.
SPEAKER_00It really highlights a beautiful, persistent continuity in human medicine. The ancient instincts were always pointing in the right direction. It just took us a few millennia to develop the anatomical understanding and the technology to permanently solve the problem.
Medical Disclaimer And Closing Thought
SPEAKER_01Before we wrap up today's deep dive, we do need to share an important note regarding this content. This discussion is intended as a source material resource for education. Medical decisions should always be individualized based on current evidence-based guidelines and clinical judgment and directed by a physician.
SPEAKER_00Absolutely essential to keep in mind.
SPEAKER_01So the next time you instinctively grab that bag of frozen peas to press against your forehead, just remember that you are actively participating in a thirty five hundred year old tradition of neuromodulation. Thanks for joining us on this deep dive, and we'll see you next time.
