BrainWaves #67 The mind's eye

MedLink Neurology Podcast is delighted to feature selected episodes from BrainWaves, courtesy of James E Siegler MD, its originator and host. BrainWaves is an academic audio podcast whose mission is to educate medical providers through clinical cases and topical reviews in neurology, medicine, and the humanities, and episodes originally aired from 2016 to 2021. Originally released: July 18, 2017 We rely heavily on our vision to perceive the world around us. (You wouldn't even be able to read this unless your vision were fully intact.) But what happens when that visual information is registered poorly by the eyes or the information is erroneously translated by a damaged nervous system? Cognitive neuroscientist and visual systems specialist, Dr. Geoff Aguirre joins in this segment on how structural neurologic injury contributes to abnormalities in visual perception. Produced by James E Siegler & Erika Mejia. Music by MMFFF, Peter Rudenko, Three Chain Links, and Marcos H. Bolanos. Voiceover by Erika Mejia. BrainWaves' podcasts and online content are intended for medical education only and should not be used for routine clinical purposes. REFERENCES Barton JJ. Disorders of higher visual processing.
