Simulation of different firing patterns in paired spider mechanoreceptor neurons: the role of Na(+) channel inactivation.

abstract：:This study examined the effect of chronic exposure to ethanol on gamma-aminobutyric acid type-A (GABA(A)) receptor-mediated responses of layer II pyramidal neurons of the piriform cortex. Slices containing the piriform cortex were derived from pair-fed adult rats maintained on ethanol-supplemented or control liquid di...
