Direct projections from the deep layers of the superior colliculus to the subthalamic nucleus in the rat.
Direct projections from the superior colliculus to the subthalamic nucleus were found in the rat in antero- and retrograde tracing experiments; these projections arose mainly from the deep layers of the superior colliculus at its middle to caudal levels. The present findings suggest that signals from the deep layers of the superior colliculus may modulate the basal ganglia activity during orienting behavior.
