Jeremy Quinby has a conversation with Nikki Kenward about her recent book, It's All In Your Gut - Let Your Second Brain Guide You To Optimal Health. Together they discuss new science backing the validity of calling the gut our second brain, shared cells, the vagus nerve and what may cause the gut to decrease in function. They also discuss their work as craniosacral therapists and it's use in regulating this system, especially in the case of childhood trauma and adult dis-regulation.
