GABA AND GLYCINE HAVE DIFFERENT EFFECTS ON MONAURAL RESPONSE PROPERTIES IN THE DORSAL NUCLEUS OF THE LATERAL LEMNISCUS OF THE MOUSTACHE BAT

1. We studied the monaural response properties of 81 neurons in the dorsal nucleus of the lateral lemniscus (DNLL) of the mustache bat before and during the iontophoretic application of antagonists that blocked gamma-aminobutyric acid-A (GABA(A)) receptors (bicuculline) or glycine receptors (strychnine). The main finding is that GABAergic inhibition had substantial effects, whereas glycine had little or no effect on the activity evoked by contralateral stimulation.
