The glymphatic system is a macroscopic waste clearance network that utilizes perivascular channels created by astroglial cells to eliminate neurotoxic metabolites, such as amyloid-β, from the central nervous system. Because the brain lacks traditional lymphatic vessels, it relies on the continuous exchange between cerebrospinal fluid (CSF) and interstitial fluid (ISF) to maintain homeostasis. Acco...

This episode explores advanced methods for recording and analyzing EEG responses evoked by transcranial magnetic stimulation, with a focus on TMS-evoked potentials, or TEPs. Drawing on recent research by Zrenner and Ziemann (2024), Beck et al. (2024), Casarotto et al. (2022), Kabir et al. (2024), and Vasileiadi et al. (2026), the episode examines how scientists are improving the precision, reliabi...
