Previously, we reported that activation of muscarinic receptors modulates N-methyl-D-aspartate (NMDA) receptor-mediated synaptic transmission in auditory neocortex [Aramakis et al. (1997a) Exp Brain Res 113:484-496]. Here, we describe the muscarinic subtypes responsible for these modulatory effects, and a role for
