title: Projections to the superior colliculus from the dorsal hypothalamic area and other prosencephalic structures derived from the embryonic subthalamic longitudinal band of the diencephalon.
abstract: After injections of an aqueous solution of horseradish peroxidase (HRP) restricted to the superior colliculus of the cat, labeled neurons were found ipsilaterally in the dorsal hypothalamic area, lateral hypothalamus, zone incerta, reticular thalamic nucleus and ventral lateral geniculate. In most cases labeled neurons were observed in the same structures of the contralateral side. Some scattered neurons were observed in other hypothalamic structures and the globus pallidus. Most of these prosencephalic formations are subthalamic derivatives, thus having a common embryologic origin.
