Case pg348,349, fig5d-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 anterior medial preoptic area Paper describes a.m.p.a. as separate region .

Case pg351,352, 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 in preoptic region ros. to SCN. lat. component of RHT labeled terminals and fibres within or lateral to the lateral haf of the medial preoptic area. Terminal label evident in ven. 1/2 of the lateral part of the medial preoptic area.

In the preoptic regions, relatively sparse numbers of marked cells were observed in the median preoptic, anteroventral periventricular, medial preoptic, anterodorsal preoptic, anteroventral preoptic, and parastrial nuclei, as well as in the undifferentiated part of the medial preoptic area. In addition, a very few retrogradely labeled neurons were noted in the lateral preoptic area (Fig. 3C-F).

...sparse inputs to lateral zone of the ventral lateral geniculate nucleus, the intergeniculate leaflet, and the parvicellular part of the subparafascicular nucleus (Fig. 5J–L).

Case pg59. Soma notes PHA-L was injected iontophoretically into 35 adult male Wistar rats. Terminal notes Injections involving the intergeniculate leaflet gave rise to a substantial number of fibres to the hypothalamus. In the LHA, innervation was mostly concentrated in the rostral and ventromedial parts. Small number of contra LHA.
