Electrophysiological Features of Neurons in the Mesencephalic Trigeminal Nuclei

[摘要] Mesencephalic trigeminal nucleus (Mes V) neurons represent an uncommon class of primary sensory neurons. Besides receiving somatosensory information, Mes V neurons are also involved in regulating multisensory information. The present review first describes the passive features as well as three important currents, followed by a distinct excitability classification and a description of the excitability transition of Mes V neurons. Furthermore, their resonance property, the existence of membrane oscillation and electrical coupling which may promote strong synchronization, as well as their function in controlling stretch reflex activity, are discussed.
