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.

RetinaRetrochiasmatic area moderate/strongnot knownCholera toxin conjugated to HRP
Case pg348, fig3k. 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 entered the retrochiasmatic area. Along this path (extension of the medial component of the RHT) terminals were evident in the retrochiasmatic area.
