The facilitatory actions of muscarine on synaptic transmission were measured in rat superior cervical ganglia in vitro. Muscarine (300 nmol/l) induced increases in submaximal population action potentials, which were mimicked by the M1 receptor agonist McN-A-343 (1 mumol/l) and antagonized by the M1 receptor antagonist pirenzepine (100 nmol/l) and telenzepine (100 nmol/l), but not by the M2 receptor antagonist AF-DX 116 (1 mumol/l). Slow excitatory postsynaptic potentials recorded from curarized rabbit isolated superior cervical ganglia were also blocked by telenzepine (300 nmol/l) but not by AF-DX 116 (3 mumol/l). It is concluded that M1 receptors mediate the excitatory actions of muscarinic agonists in these sympathetic ganglia.
