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. Episodes originally aired from 2016 to 2021.

Originally released: August 22, 2019

This week on the BrainWaves podcast, finally...a REAL show about BRAINWAVES! Dr. Carolina Maciel of the University of Florida schools Jim Siegler on how to read EEG and interpret abnormal patterns across the ictal-interictal continuum.

Produced by James E Siegler and Carolina Maciel. Music courtesy of Chris Zabriskie, Montplaisir, Rafael Archangel, Steve Combs, Unheard Music Concepts, and Siddhartha. Sound effects by Mike Koenig and Daniel Simion. BrainWaves' podcasts and online content are intended for medical education only and should not be used for clinical decision-making.
