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 pg76, fig2. Soma notes PHA-L was injected in the ?parataenial nuc. --See fig 1 for examples of inj sites, but not for every case-. The diameter of the inj sites varies from 150 to 600u? A very small injection of PHA-L was placed in the parataenial thalamic nucleus.. Terminal notes resulting labelling in medial prefrontal cortex predominantly involves the medial orbital ?cortical area. Terminal plexus is concentrated in its dorsal part and involves {1,3} and to a lesser extent {5}.
