Retina	Anterior hypothalamic area	moderate/strong	not known	Cholera toxin conjugated to HRP	Case pg308, fig12,15. 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: 2) extension of SCN axonal plexus into the AHA and the RCA. this is sparse rostrally and grows increasingly dense caudally, where it extends to a wide zone caudal to the SCN including AHA and RCA.		Johnson RF, Morin LP, Moore RY., 1988
Retina	Anterior hypothalamic area	moderate	not known	Cholera toxin conjugated to HRP	Case pg348,350, fig3k-p. 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 RHT swept dorsally throught the central part of the anterior hypothalamic area where it began to disperse. terminals evident in med. anterior and central anterior hypothalamic areas..

Anterior hypothalamic area	Periaqueductal gray	light	not known	fluorescent tracers	Case pg240. Soma notes The anterior hypothalamic area contained the highest concentration of retrogradely labeled neurons in the rostral hypothalamus. True blue labeled neurons filled the entire AHA. Contra AHA also contained many retrogradely labeled neurons, i:c=4:1. Terminal notes 3 injs were placed at different rostrocaudal levels within periaqueductal gray. E18 most rostral, E53 most caudal. E31 immediately btwn these 2..	Watts AG, Swanson LW., 1987
