Prolonged Stimulation-Induced Afterdischarges of Hippocampal CA1 Pyramidal Cells After Ischemia In Vivo

Neurochemical Monitoring in the Intensive Care Unit

Abstract

Transient cerebral ischemia causes selective death of hippocampal CA1 pyramidal cells after a period of 3–5 days [1]. We previously demonstrated that Schaffer collateral/CA1 responses of the rat are potentiated beginning at 6–8 h after transient cerebral ischemia in vivo [2]. The present study examined whether the utilization of N-methyl-d-aspartate (NMDA) receptorcoupled ion channels is increased or not during the period in which postischemic potentiation (PIP) of Schaffer collateral/CAl responses is observed.
