Case pg352. 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 Med. component of the RHT?in addition, labeled fibres and terms were found lateral to the lateral boundary of the SCN, in the lateroanterior hypothalamic nucleus. Lat component diffuse labeling in the lateroanterior hypothalamic nucleus was evident.
