Pupillo-motor areas in the rabbit visual cortex.
Pupillo-motor areas in the visual cortex of the rabbit were studied. Electrical stimulation of the rabbit visual cortex induced pupillary constriction or dilation. The low threshold area (0.5-1.0 mA) for pupillary dilation was in the form of a narrow band extending rostro-caudally along the boundary between the striate cortex (VI) and the occipital cortex (VII), where the binocular area of the visual field is represented. The pupillo-constrictory cortical points were also identified in the caudal part of the splenial gyrus (lateral part) and the pupillo-dilator points in the rostral part of the gyrus (lateral part).
