Thanks to pop culture, dopamine is commonly associated with pleasure-seeking and addiction, but its function goes way beyond that.
Despite the fact that only about 400 000 out of 10 billion neurons in our brain produce it, the importance of natural dopamine for our survival is tremendous. It is responsible for us making a difference between what is good and what is bad for us, our ability to compare expectations to reality, but also for basic functions like physical movement. And it’s not only survival of humans it has a role in - dopamine systems are something we share with organisms as simple as fruit flies.
To find out about dopamine function and current research into it, Kim and Alessia interview professor Ulrik Gether, head of the Department of Neuroscience at Copenhagen University. A trained medical doctor, Gether studied at Copenhagen University and Stanford University Medical School, and is now a leading researcher on neurotransmitters, dopamine in particular. He currently co-manages the project called Attention to Dopamine, an interdisciplinary endeavor aiming to provide better understanding of the relations between dopamine and Attention-Deficit Hyperactivity Disorder (ADHD).
Even more importantly, he tells us about practical ways in which we can affect dopamine production to improve our lifestyles - its role in changing habits and how to prevent relapse into old bad habits. Furthermore, we find out about the applications of dopamine in Parkinson’s disease treatment, ADHD, and schizophrenia, and get to peek into the cutting-edge research of dopamine Gether does at his lab at Mærsk Tower, Copenhagen.
