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.

Case pg109, table1, fig1. Soma notes Labeled perikarya in low to moderate density are found in the ipsilateral MTNd, VTRZ, nucleus paranigralis & compact & reticular portions of substantia nigra. Terminal notes The portion of an injection site which would retrogradely transport HRP from the pars medialis of the deep mesencephalic nucleus is illustrated in fig1B.
