Motor neurons located in a paramedian position dorsal to the medial longitudinal fasciculus. Ovoid cellular mass in the tecturn of the mesencephalon. Belongs to the auditory system. Concerned with audition. Continuation of the same structures seen at more caudal levels.
Fibers project, after decussation, into the red nucleus and ventral lateral nucleus of the thalamus.
Processes of pseudounipolar neurons in the mesencephalic nucleus of the trigeminal nerve. Neurons are sparsely scattered on each side of the tract. Continuation of the same structure seen at more rostral and more caudal levels. All rights reserved.
