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.

In contrast, an injection of true blue centered in the rostroventral tip of the GP and adjacent parts of the SI (see GP6 in Fig. 4) resulted in the retrograde labeling of cells throughout the nucleus accumbens, except for the most medial part of the nucleus (rostra1 to the level illustrated), and in adjacent regions of the caudoputamen.
