In the episode, Karl explains his unique career path that led to the development of optogenetics—a revolutionary technique that uses specialized light-sensitive ion channels to precisely control the activity of select populations of neurons. Karl provides a concise overview of how optogenetics works and how it can be used to better understand mental illness, to identify the neurons responsible for specific behaviors, and to guide development of new treatments. Karl uses his experience as a practicing psychiatrist to provide deep insights into depression, anxiety, autism, and personality disorders and explains the role of optogenetics in mapping out brain regions responsible for common mental health afflictions.
