Case pg307-308, fig12. Soma notes 2 adult male hooded rats and 5 adult male albino rats were used. each received an injection of CT-HRP into the posterior chamber of the eye.. Terminal notes retinohypothalamic tract 3 components: 1) largest is innervation of SCN. Rostral SCN: a very dense band of terminals at border of SCN and optic chiasm, Mid SCN: most of ven.lat. component of nuc filled with dense terminal plexus, remainder less dense.

Case pg3, fig1. Soma notes 30 animals used for autoradiography study. Each received 1 injection of either L-leucine-3H or L-proline-3H into the posterior chamber of one eye. Terminal notes The autoradiographic material provided substantial evidence for a retinohypothalamic tract. The hypothalamic nuclei themselves were free of labelling save for the suprachiasmatic nucleus, both ipsi and contra, especially in ventral 1/2.

Case pg208,211, fig3I-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 pg76, fig2. Soma notes PHA-L was injected in the ?parataenial nuc. --See fig 1 for examples of inj sites, but not for every case-. The diameter of the inj sites varies from 150 to 600u? A very small injection of PHA-L was placed in the parataenial thalamic nucleus.. Terminal notes resulting labelling in medial prefrontal cortex predominantly involves the medial orbital ?cortical area. Terminal plexus is concentrated in its dorsal part and involves {1,3} and to a lesser extent {5}.
