BrainWaves: A Neurology Podcast


Aug 2, 2018

How visual information transforms from pixels into people is more complex than dots becoming lines, lines becoming shapes, and shapes becoming faces. Your brain makes assumptions about all kinds of sensory information--even without you knowing it. Dr. Geoffrey Aguirre, a neuroscientist who specializes in vision processing, explains how we know what we can't really explain.

Produced by James E. Siegler & Geoff Aguirre. Music by Cullah, Jon Watts, Lovira, Loyalty Freak Music, and Scott Holmes. Sound effects by Mike Koenig, Daniel Simion. BrainWaves' podcasts and online content are intended for medical education only and should not be used for clinical decision making.
