| F F Johansen, N H Dieme. Enhancement of GABA neurotransmission after cerebral ischemia in the rat reduces loss of hippocampal CA1 pyramidal cells. Acta neurologica Scandinavica. vol 84. issue 1. 1991-11-21. PMID:1656687. |
we conclude that enhancement of postischemic gaba neurotransmission, during the first 2-3 days after ischemia, may reduce the ischemic ca1 damage through a continuous increase in hippocampal gaba extracellular levels (no-328), or through an increase in sensitivity to gaba neurotransmission (diazepam). |
