title: Electrophysiological characteristics of cholinergic and non-cholinergic neurons in the rat medial septum-diagonal band complex.
abstract: We examined the electrophysiological properties of cholinergic and non-cholinergic neurons in the medial septum-diagonal band complex (MSDB) of the rat in the in vitro slice preparation. Cells were identified electrophysiologically, filled with Lucifer yellow, fixed and processed for immunohistochemistry with fluorescent labeled anti-choline acetyltransferase (ChAT) antibody. Cholinergic and non-cholinergic neurons differed in action potential parameters, spike afterpotentials and in current-voltage relationships. In addition, cholinergic neurons expressed a potent transient outward rectification in response to a depolarizing current pulse.
