Case pg348,349, fig5a-f. Soma notes 36 female Sprague-Dawley rats weighing 200-350g. 10 microliters of CT-HRP(.20%-.40%) were injected into one eye ?behind the lens into the vitreous chamber of the eye. pressure injection over 1 min. Terminal notes Medial component of the RHT included labeled fibres and terminals found near the midline involved the medial half of the medial preoptic area terminals evident in the ventral part of the medial preoptic nucleus.

Case pg368,378. Soma notes Many dye labeled neurons were present in the POSC. Preoptic suprachiasmatic region is an ill defined area containing several distinct cell groups in periventricular zone around optic recess & rostral 3rd ventricle.. Terminal notes B1.3 received a 0.5u inj of 10% primuline/2.5% DAPI into the ventral midbrain & subsequently a nuclear saturating dose of [3H] E2. Inj site involved both VTA & rostral periaquductal gray. --Huge inj site, see fig 2--.
