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.
