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 pg317, fig10. Soma notes Most of retrogradely labeled neurons located in deep layers of infralimbic area while fewer labeled neurons were found rostrally & dorsally in or near layer V of prelimbic and anterior cingulate areas.. Terminal notes injs of WGA-HRP into medial mammiliary nucleus. Inj centred in medial part of medial mammiliary nucleus, with spread into lateral parts of medial mammiliary nucleus..
