Abstract

A study was made of changes in nuclear neurones of the anterior hypothalamus in 8 cats aged 3-4 weeks, which survived for varying times after unilateral cutting of the optical nerve. The presence of retrograde-degenerated neurones was revealed mainly in the supraoptic and paraventricular nuclei of the anterior hypothalamus, opposite to the cut optical nerve. Single destructive changer neurones were detected in the suprachiasmatic, medial and lateral nuclei in the preoptic area of the anterior hypothalamus. It is inferred that anterior hypothalamus neurones participate in the innervation of the cat eye balls. The initial points of centrifugal fibers of the anterior hypothalamus towards the eye are as follows (diminishing in terms of importance): supraoptic, paraventricular, suprachiasmatic, medial and lateral nuclei of the preoptic area.
