Perlia's nucleus

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]
