Opposite effects of cholinergic agents and benzodiazepine receptor ligands in a passive avoidance task in rats.

abstract：:Mouse acetylcholine receptors (AChRs) consisting of either the embryonic form (2 alpha, 1 beta, 1 delta and 1 gamma) or the adult form (2 alpha, 1 beta, 1 delta and 1 epsilon) were expressed in Xenopus laevis oocytes. As expected, the single channel conductance was approximately 52 pS and the exponential decay time co...
