Cortical spreading depression and peri-infarct depolarization in acutely injured human cerebral cortex.
Electrocorticographic (ECoG) activity was recorded for up to 129 h from 12 acutely brain-injured human patients using six platinum electrodes placed near foci of damaged cortical tissue. The method probes ECoG activity in the immediate vicinity of the injured cortex and in adjacent supposedly healthy tissue. Six out of twelve patients displayed a total of 73 spontaneous episodes of spreading de...
متن کاملSpreading convulsions, spreading depolarization and epileptogenesis in human cerebral cortex
Spreading depolarization of cells in cerebral grey matter is characterized by massive ion translocation, neuronal swelling and large changes in direct current-coupled voltage recording. The near-complete sustained depolarization above the inactivation threshold for action potential generating channels initiates spreading depression of brain activity. In contrast, epileptic seizures show modest ...
متن کاملSpreading and synchronous depressions of cortical activity in acutely injured human brain.
BACKGROUND AND PURPOSE Cortical spreading depression (CSD) has been much studied experimentally but never demonstrated unequivocally in human neocortex by direct electrophysiological recording. A similar phenomenon, peri-infarct depolarization, occurs in experimental models of stroke and causes the infarct to enlarge. Our current understanding of the mechanisms of deterioration in the days afte...
متن کاملDifferent susceptibility of acutely injured and chronically epileptic brain tissue to induction of cortical spreading depolarization and seizures
Epileptic seizures and cortical spreading depolarization (CSD) are two patterns of electrophysiological activity that can be studied in the healthy and in the injured brain. They can be triggered by the same pathologies, such as stroke, traumatic brain injury and fever, with disruption of the blood brain barrier as a common hallmark. The latter is associated with entry of serum components into ...
