The nucleus for accommodation in the midbrain of the macaque.

This paper reports upon: (1) the relationship between iris-bulge and accommodation of the eye; (2) the stereotaxic localization of midbrain sites that produce iris-bulge and changes in the retinoscopic reflex (accommodation); (3) the patterns of response from excitation of sites within the oculomotor nuclear complex; and (4) the effect of stimulation of the parasympathetic nucleus on the intraocular pressure.
