| Name: | CaP motoneuron |
|---|---|
| Synonyms: | CAP motoneurons, caudal primary motoneuron |
| Definition: | A primary motor neuron part of the spinal cord. The CaP motoneuron is found within 1 soma diameter of the ventral root. The axon of the CaP motoneuron extends ventrally from the ventral root, within the space between the notochord and the medial surface of the axial muscles. Below the notochord, the axon extends within the ventral median septum to the ventral edge of the axial muscles, where it turns dorsally and laterally to project over the lateral surface of the axial muscles. |

| Name: | inhibitory postsynaptic potential |
|---|---|
| Synonyms: | IPSP, regulation of inhibitory post-synaptic membrane potential |
| Definition: | A process that causes a temporary decrease in postsynaptic membrane potential due to the flow of negatively charged ions into the postsynaptic cell. The flow of ions that causes an IPSP is an inhibitory postsynaptic current (IPSC) and makes it more difficult for the neuron to fire an action potential. |
