| postsynaptic cell | In a chemical synapse, the cell that receives a signal (binds neurotransmitter) from the presynaptic cell and responds with depolarisation In an electrical synapse, the postsynaptic cell would just be downstream, but since many electrical synapses are rectifying, one of the two cells involved will always be postsynaptic. (18 Nov 1997) |
| postsynaptic membrane | That part of the plasma membrane of a neuron or muscle fibre with which an axon terminal forms a synaptic junction; in many instances, at least part of such a small postsynaptic membrane patch shows characteristic morphological modifications such as greater thickness and higher electron-density, believed to correspond to the transmitter-sensitive receptor site of such synapses. (05 Mar 2000) |
| postsynaptic potential | In a synapse, a change in the resting potential of a postsynaptic cell following stimulation of the presynaptic cell. For example: in a cholinergic synapse, the release of acetylcholine from the presynaptic cell causes channels to open in the postsynaptic cell. Each channel opening causes a small depolarisation, known as a miniature end plate potential (mepp), these sum to produce an excitatory postsynaptic potential. (18 Nov 1997) |
| inhibitory postsynaptic potential | The change in potential produced in the membrane of the next neuron when an impulse which has an inhibitory influence arrives at the synapse; it is a local change in the direction of hyperpolarization; the frequency of discharge of a given neuron is determined by the extent to which impulses that lead to excitatory postsynaptic potential's predominate over those that cause inhibitory postsynaptic potential's. (05 Mar 2000) |
| excitatory postsynaptic potential | The change in potential which is produced in the membrane of the next neuron when an impulse which has an excitatory influence arrives at the synapse; it is a local change in the direction of depolarisation; summation of these potential's can lead to discharge of an impulse by the neuron.
