Case pg353-4. 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 fibres can be seen in stria terminalis coursing rostrally from these more caudal levels. This pathway gives rise to the thalamic label reported earlier (anterior dorsal, anterior ventral thalamic nuc. and bed nuc. of the stria terminalis.).

Case pg600, fig9,8C, obs. Soma notes subcortically, cell bodies were labeled in ?AD nucleus of the thalamus, --density taken from figs 7 & 9-. Discussion: Rga is primarily innervated by the AD, LD, POST, caudal Rgb and contralateral Rga. Terminal notes Injections of the retrograde tracers (FB/FG) into Rga.
