RetinaMedial preoptic area light/moderatenot knownCholera toxin conjugated to HRP
Case pg348,349, fig5d-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 anterior medial preoptic area Paper describes a.m.p.a. as separate region .

Case pg236-7, fig6,7. Soma notes The medial preoptic & anterior hypothalamic areas were filled with labeled cells, but density decreased around SCh & only occasional cells seen in nucleus itself.. Terminal notes true blue was injected in the lateral septal nucleus of 4 animals (fig6). E22 was liquid inj into LSv & LSi. E27 was crystal implant into LSv.
