Case pg348, fig2. 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: a few fibres were seen in the PVN in some rats but this label was not consistently evident.

At mammillary levels, a few retrogradely labeled cells were reliably observed in the ventral premammillary and posterior nuclei (Fig. 3L).
