title: Enhancement of current induced by superfusion of GABA in locus coeruleus neurons by pentobarbital, but not ethanol.
abstract: gamma-Aminobutyric acid (GABA), pentobarbital and ethanol were applied by bath superfusion to rat locus coeruleus (LC) neurons in a brain slice preparation. The GABA-induced current and conductance increase was measured with single-electrode voltage clamp. Pentobarbital potentiated the GABA-induced current and conductance increase in all LC neurons tested. In contrast, ethanol did not alter the current and conductance increase induced by bath application of GABA to LC neurons.
