Case pg392, fig8,9. Soma notes anterograde as well as retrograde label seen in ?medial lateral & velntrolateral orbital areas. --Fig8: Fairly dense/moderate labeling shown-. Terminal notes relatively large WGA-HRP injections ?RH-8159, inj located centrally in rostral MD & includes all segments, only little spread into stria medullaris, medial habenula paraventricular nucleus & caudal aspect of parataenial nuc..

Case pg393, fig10,11. Soma notes frontal pole cells are massively labeled. In caudal dirn antero & retro-grade labeling continues laterally into lateral orbital region?medial ventral & ventrolateral orbital regions conain a lesser amount of anterograde label?--only label seen in ORBl-. Terminal notes In case RH-8180 the inj of WGA-HRP was deposited in the cau. half of MD, including its medial, central and lateral segments. The inj site involves the medial habenular and posterior paraventricular nuclei; paracentral nucleus is also slightly involved..
