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 pg7-8, fig4. Soma notes HRP +ve cells observed in subicular cortex thorughout rostrocaudal extent of dorsal hippocampal formation with a few labeled cells also present in posterior subicular cortex. Confined to a single layer in prosub, sub & presub.. Terminal notes HRP injected into components of ATN in 22 animals. Case106: In this case (& repeated in 5 animals) a large injection included lateral portion of anteromedial nucleus & adjacent part of anteroventral nucleus..

Case pg434, fig11. Soma notes Following injection into central part of AV (R572)

Case pg433-4, fig10. Soma notes 2 cases available for injections of AV at its caudal 1/3 level. In a case with injection restricted to dorsolateral part of AV (R514)

Case p433, fig8. Soma notes A case with inj into ventral part of AV (R506)

Case pg433, fig6. Soma notes At midrostrocaudal level of AV, injs were confined to dorsal & lateral, dorsal, ventral & medial part. In case R532, an injection involved dorsal & lateral parts of AV.. Terminal notes Terminals ?hereas in medialmost part of midseptotemporal subiculum seen in deep part of pyramidal cell layer, they were seen in deep part of pyramidal cell layer. --Fig6: mod--.

Case pg507, fig2. Soma notes rat 65: PHA-L injection labeled pyramidal cells in caudal 1/3 of subiculum proper at midtemporal levels of structure. Small number of nonpyrmadidal cells situated adjacent to angular bundle also labeled by this inj.. Terminal notes Rostrally directed projection from subiculum innervates all layers of regio superior --CA3-- & molecular layer of regio inferior --CA1--. Numerous PHA-L stained fibres are also present in molecular layer of area dentata..

The LHA receives the strongest field CA1 projection of any hypothalamic component. LHA medial regions receive a moderate projection of varicose fibers and terminal boutons from the rostral end of the LHA to about mid-rostrocaudal levels of the ventromedial nucleus, where the projection becomes considerably denser (Fig. 3D-G).

Rostroventrally, a tight group of PHAL-labeled fibers is observed in the ventromedial corner of the LHA anterior region’s ventral zone, and a few labeled fibers are also seen in the intermediate zone (Fig. 3D-F).

Rostrodorsally, a moderate plexus of varicose fibers with boutons occupies the LHA juxtaparaventricular region and an adjacent medial expanse of the anterior region’s dorsal zone, dorsal to the anterior hypothalamic nucleus (Fig. 3E,F).

At the level of the ventromedial nucleus, the terminal field becomes significantly denser (Fig. 3G). Here, the LHA’s juxtadorsomedial region, and dorsal and ventral zones of the juxtaventromedial region, all contain a moderately dense terminal field.
