Case pg208,212, fig3H-L. Soma notes 3 PHA-L injs were virtually limited to the SCh, with less than 5% of labeled neurons outside boundaries of nucleus itself. Injs A7 & A54 tended to label cells in ventral part of nucleus, while inj A25 extended more dorsally. Terminal notes 5th Pway. Both thick & thin fibres with large & small varicosities were present in the anterior hypothalamic area..

Case pg208,213, fig3H. Soma notes 3 PHA-L injs were virtually limited to the SCh, with less than 5% of labeled neurons outside boundaries of nucleus itself. Injs A7 & A54 tended to label cells in ventral part of nucleus, while inj A25 extended more dorsally. Terminal notes 6th Pway. A relatively small group of fibres appears to course posteriorly & laterally from SCh through retrochiasmatic & anterior hypothalamic areas to end in ventral & ventrolateral parts of cell-sparse zone surrounding VMH. Thin, small varicosities..
