Editor’s Note: From February 2-5, 2020, neuroscience researchers gathered in Keystone, Colorado, to attend a symposium, Somatosensation: From Detection to Perception. This symposium, which was held jointly with the symposium, Pain: Aligning the Target, focused on somatosensation – how the body senses pain, touch, temperature, itch and body position. Alexander Chesler, one of the organizers of the symposium, is a researcher who investigates somatosensation at the US National Institutes of Health’s National Center for Complementary and Integrative Health. He sat down at the symposium for a podcast with freelance writer Stephani Sutherland to discuss how somatosensation works and what happens in the nervous system when it goes awry. Take a listen below.
