Spitzka's nucleus --> Perlia's nucleus

A small cell group located between the somatic cell columns of the oculomotor nuclei. Since it is placed between the groups of motor neurons innervating, respectively, the left and right medial rectus muscles, the nucleus is considered to possibly represent an integrating mechanism for ocular convergence.

Synonym: convergence nucleus of Perlia, spitzka's nucleus.
