Published in 2025 at "Synapse"

DOI: 10.1002/syn.70021

Abstract: Cortical spreading depolarization (CSD) describes a slow, sustained depolarization within the cerebral gray matter that renders neurons unable to fire action potentials, resulting in widespread neuronal depression. CSD has been observed in stroke, subarachnoid hemorrhage,… read more here.

Published in 2019 at "Heart and Vessels"

DOI: 10.1007/s00380-019-01383-4

Abstract: AbstractMyocardial ischemia changes the electrophysiological properties of the myocardium, but it is difficult to detect the abnormalities of depolarization and repolarization noninvasively in patients with coronary artery disease. Depolarization and repolarization abnormalities were retrospectively investigated… read more here.
