Sending structure	Receiving structure	Strength of projection	Type of connection	Technique	General description	Associated reference
Retina	Suprachiasmatic nucleus	strong	not known	Cholera toxin conjugated to HRP	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.	Johnson RF, Morin LP, Moore RY., 1988
Retina	Suprachiasmatic nucleus	strong	not known	Cholera toxin conjugated to HRP	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..	Levine JD, Weiss ML, Rosenwasser AM, Miselis RR., 1991
Retina	Suprachiasmatic nucleus	moderate/strong	not known	autoradiography	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.	Moore RY, Lenn NJ., 1972

Suprachiasmatic nucleus	Anteroventral periventricular nucleus	light	not known	PHAL	Case pg208, fig3B. 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 1st Pway. Some of most ros fibres enter anteroventral preoptic & anteroventral periventricular nucleus?Thick convoluted fibres (narrowly spaced varic) & thinner linear fibres (widely spaced varic). V few fibres branch/give rise to terminal boutons..		Watts AG, Swanson LW, Sanchez-Watts G., 1987
