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.

Within the thalamus, labeling was prominent in the parataenial nucleus, the dorsocentral portion of MD, the ventromedial margin of the submedial nucleus, and the medial aspect of the ventromedial nucleus (Fig. 1E-G). Other thalamic nuclei containing labeled cells were the paraventricular, rhomboid and reuniens. Collator note: Swanson Atlas Levels 31-32.
