Retina	Medial preoptic nucleus	light/moderate	not known	Cholera toxin conjugated to HRP	Case pg348,349, fig5a-f. 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 included labeled fibres and terminals found near the midline involved the medial half of the medial preoptic area terminals evident in the ventral part of the medial preoptic nucleus.

Periaqueductal gray	Ventral tegmental area	light	not known	HRP	Case pg149, R50(no fig), table3. Soma notes smaller numbers of cells. Terminal notes HRP inj into vemtrolateral division (only one inj produced labelling).		Beitz AJ., 1982
Periaqueductal gray	Ventral tegmental area	moderate	not known	HRP	Case pg109, table1, fig1. Soma notes In addition moderate bilateral label is observed in the VTRZ, the nucleus parabrachialis pigmentosus and paranigralis and the compact part of the substantia nigra. Terminal notes The supraoculomotor portion of the periaqueductal gray, has been injected (HRP) in 3 rabbits & 1 rat. In all 4 cases the supraocmot/PAG has been successfully injected with minimal spread to the adjacent occulomotor nucleus..		Giolli RA, Blanks RH, Torigoe Y, Williams DD., 1985
