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 pg348,349-50, fi3,6. Soma notes 36 female Sprague-Dawley rats weighing 200-350g. 10 microliters of CT-HRP(.20%-.40%) were injected into one eye behind the lens into the vitreous chamber of the eye. pressure injection over 1 min. Terminal notes Medial component of the RHTa) inbtwn 2 SCNs under v3, b) ven. lat. to SCN, appear to cradle it high density of terminal labeling in and around SCN. (ven.lat. parts of ros. SCN, venlat. dorlat. parts of cau. SCN.) dormed. subncl of SCN largely spared..

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 pg240. Soma notes SITS labeled neurons were seen in smaller numbers (than D2/E8) in D7 & D8. Labeled neurons in dorsolateral & perinuclear regions of the SCh.. Terminal notes injections in D7, D8 & D10 all labeled dorsal & ventral parts of the lateral geniculate includeing the intergeniculate leaflet.

Case pg208,212, fig4. 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 4th Pway. Relatively small number of labeled fibres ?can be traced to a term field in ventral geniculate nucleus (including the IGL). Proximal to lateral geniculate nucleus these fibres are generally V thin with small varicos & few terminal boutons.

Case pg404, 407. Soma notes neurons retrogradely labeled in IGL following FG inj into either SCN or contralateral IGL are distributed in a pattern essentially identical to retinal afferents or distribution of NPY+ neurons. Terminal notes Injecting fluorescent tracer into either SCN (bilaterally) or IGL. 50-100nl of fluoro-gold injected stereotaxically (n=10).

not mentioned

Case pg59. Soma notes PHA-L was injected iontophoretically into 35 adult male Wistar rats. Terminal notes Injections involving the intergeniculate leaflet gave rise to a substantial number of fibres to the hypothalamus. In the LHA, innervation was mostly concentrated in the rostral and ventromedial parts. Small number of contra LHA.
