Spreading Cortical Depression - an overview ScienceDirect Topics
Cortical spreading depression (CSD) or spreading depolarization (SD) is a wave of electrophysiological hyperactivity followed by a wave of inhibition. Spreading depolarization describes a phenomenon characterized by the appearance of depolarization waves of the neurons and neuroglia that … See more Neuroscientists use the term cortical spreading depression to represent at least one of the following cortical processes: • The spreading of a self-propagating wave of cellular depolarization in the cerebral cortex See more • Transient ischemic attack • Spreading depression: discovery See more • braintsunamis.com - Spreading Depolarization and Spreading Ischemia • COSBID.org The Co-Operative Studies on Brain Injury Depolarizations is an international research consortium focused on the role of spreading depolarizations in acute neurologic injury See more WebMay 2, 2024 · Spreading depression (SD) is a slowly propagating wave of near-complete depolarization of neurons and glial cells across the cortex. SD is thought to contribute to the underlying pathophysiology of migraine aura, and possibly also an intrinsic brain activity causing migraine headache. WebHowever, the more popular migraine theories suggest a contiguously spreading wave of cortical neuronal depression. 12, 31 The perfusion changes may not be the inciting event; rather, the perfusion abnormality may be the response of the autoregulatory mechanisms to underlying neuronal depression. 5 – 10, 12, 13, 29, 31 – 33 This concept is … salads with amaranth
