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 pg313, fig1. Soma notes large numbers of retrogradely labeled perikarya were found bilaterally in all layers of dorsal & ventral portions of subiculum. Terminal notes case illustrated in figure1, WGA-HRP inj site centred in midline of medial mammiliary nucleus & included most of the subnuclei of MM bilaterally. LM spared but some spread into medial SUM.
