Depolarization-induced suppression of inhibition (DSI) is a process whereby brief approximately 1-s depolarization to the postsynaptic membrane of hippocampal CA1 pyramidal cells results in a transient suppression of GABA(A)ergic synaptic transmission. DSI is triggered by a postsynaptic rise in [Ca(2+)](in)

Efflux of various amino acids from rat brain slices was determined under resting or depolarizing conditions. Slices of neocortex, hippocampus, striatum, cerebellum, mesodiencephalon, pons-medulla, and spinal cord were depolarized by K+ (50 mM) or veratrine (33 micrograms/ml). The 4-N,N-dimethylamino-azobenzene-4'-isothiocyanate (DABITC)

An effect of the beta-stereoisomer of kainic acid on seizures produced by intracerebroventricular injections of excitatory amino acids was tested in mice. beta-Kainic acid preferentially antagonizes myoclonic seizures induced by N-methyl-D-aspartate and quinolinate, has less pronounced anticonvulsant action against alpha-kainate

Sulfur containing amino acids such as homocysteic acid (HCA), cysteinsulfinic acid, homocysteinsulfinic acid are released by depolarization of slices from various rat brain regions in a Ca++-dependent manner. L-HCA excites caudate neurons through their N-methyl-D-aspartic acid (NMDA) receptor and potentiates

Quisqualic acid sensitizes hippocampal CA1 neurons to depolarization by L-2-amino-4-phosphonobutanoic acid (L-AP4). This sensitization to L-AP4 is known to be blocked by simultaneous exposure to L-homocysteinesulfinic acid, L-alpha-aminoadipic acid and L-serine-O-sulfate during exposure to quisqualate. We report here that these
