Direct projections from the caudal spinal trigeminal nucleus to the striatum in the cat

The results of a WGA-HRP and HRP study in the cat indicated that some neurons in the marginal zone (lamina I) of the caudal spinal trigeminal nucleus sent their axons contralaterally to the striatum; mainly to the dorsal part of the putamen, and additionally to the ventrolateral part of the caudate nucleus, at the stereotaxic rostrocaudal levels of A 13.0-A 15.5.
