Case pg208,211, fig3H-N. 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 3rd Pway. pathway courses ventrally to innervate the preoptic continuation of the bed nucelus as well as parataenial & paraventricular nuc of thalamus. In PT & PVT fibres are thin, widely spaced small varicosities and give rise to many terminal boutons..

Case pg208,212, fig3I-Q. 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. Many fibres from PVH appear to continue dorsally through midline thalamic nuclei ( reuniens, rhomboid & central medial) to end in more caudal parts of the PVT. Some branching/terminal boutons seen in PVT, much less freq in RE & RH..
