Case pg208,213, fig3N. 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. Fibres form a moderately dense plexus within dorsomedial nucleus of the hypothalamus & in the relatively cell sparse zone dorsal & medial to the ventromedial nucleus. Fibres tend to be thick/varicose, often branched & display terminal boutons..

Case pg208,213. 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..

This projection is considered to be nonexistent since the identification of fiber tracts was performed across all atlas levels.
