Toxic intraneuronal change
WebExperimentally, injury to central neurons begins only with anoxic depolarization. This potentially reversible, spreading wave typically starts 2-5 min after the onset of severe ischemia, marking the onset of a toxic intraneuronal change that eventually results in irreversible injury. WebSupporting: 15, Contrasting: 1, Mentioning: 332 - Spreading depolarizations (SD) are waves of abrupt, near-complete breakdown of neuronal transmembrane ion gradients, are the largest possible pathophysiologic disruption of viable cerebral gray matter, and are a crucial mechanism of lesion development. Spreading depolarizations are increasingly recorded …
