| Name: | Mauthner neuron |
|---|---|
| Synonyms: | |
| Definition: | Is a hindbrain interneuron. Giant reticulospinal neurons possessing thick crossed axons and positioned dorsally in the hindbrain tegmentum at the level of entrance of the eighth cranial nerve. The Mauthner neuron is paired. The M-cell has two large invariant dendrites: The lateral dendrite terminates in the sensory neuropil of the acoustico-lateral area, and the ventral dendrite terminates in the neuropil of the motor tegmentum. Fine dendrites are present, and mostly arise from three regions; from the terminus of each major dendrite and from the ventral surface of the perikaryon. |

| Name: | excitatory postsynaptic potential |
|---|---|
| Synonyms: | regulation of EPSP, regulation of excitatory post-synaptic membrane potential |
| Definition: | A process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential. |

| Name: | amplitude |
|---|---|
| Synonyms: | |
| Definition: | A physical quality of a process inhering in a bearer by virtue of the size of the bearer's maximum displacement from the 'normal' position, when periodic motion is taking place. |
