The Future of Everything

Transformational research techniques shaping our understanding of how the brain works.

Guest Karl Deisseroth is a bioengineer and a psychiatrist who has developed two of the most transformational research techniques shaping our understanding of how the brain works — optogenetics, which allows neuroscientists to control brain cells with light, and CLARITY, a way to render the brain’s gray matter transparent yet retain all its intricate wiring for easier study.  There is a vast chasm between neuroscience and psychiatry, Deisseroth says of the reasons he felt compelled to develop technology ahead of pursuing science. It was never a trade-off of one over the other, however.
