although it is difficult in our autoradiographs to distinguish between the course of the efferent fibers from the suprachiasmatic nucleus and the zones in which they terminate , our evidence favors a termination among the cells of the periventricular area , and upon dendrites of the cells in the ventromedial , dorsomedial and arcuate nuclei , which extend beyond the limits of the nuclei into the periventricular area and to the area beneath the ventromedial nucleus .
