inhibitory synapse

inhibitory synapse
A synapse in which an action potential in the presynaptic cell reduces the probability of an action potential occurring in the postsynaptic cell. The most common inhibitory neurotransmitter is GABA; this opens channels in the postsynaptic cell which tend to stabilize its resting potential, thus rendering it less likely to fire. See excitatory synapse.
