Perlia's nucleus

From Wikipedia, the free encyclopedia

Perlia's nucleus, also known as nucleus of Perlia and abbreviated as NP, is a nucleus located in the mesencephalon, in front of the Edinger-Westphal nucleus[1] and between the right and left oculomotor nuclei, it is implicated in parasympathetic oculomotor functions, possibly including input to the iris and ciliary.[2][3] Perlia's nucleus is believed to be a characteristic found exclusively in animals capable of binocular vision. Moreover, it might be an exclusive characteristic of humans, as indicated by a systematic study of monkey brains, where only 9% exhibited a clear midline group, potentially corresponding to the NP.[4]

In 1891, Perlia's nucleus was identified as a central mediator for the convergent movement of the eyes based on clinical findings in ophthalmospegias.[5] It has also recently been attributed an important role in the upward movement or gaze of the eyes.[1]
