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: August 16, 2018
Lesion localization is a critical skill for any neurologist. The so-called "cortical signs" are symptoms or examination findings, which are often associated with cortical neuron injury--aphasia, neglect, gaze preference. But they are also seen after injury to subcortical structures, including white matter tracts, the thalamus, and basal ganglia. In this week's installment of the BrainWaves podcast, we'll attempt to localize subcortical lesions based on these major cortical signs.
Produced by James E Siegler. Music by Aussenseiter, Gnagno, Yshwa, and Kevin McLeod. BrainWaves' podcasts and online content are intended for medical education only and should not be used for clinical decision-making.
