RetinaAnterior hypothalamic area moderate/strongnot knownCholera 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.

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..

Case pg237, fig6,7. Soma notes True blue labeled cells completely surrounded the region of the paraventricular nucleus of the hypothalamus in E30. The number of true blue-labeled cells lower in E33, but such cells seen in AHA & strikingly in periventricular part of PVH. Terminal notes Expt E33 involved a smaller liquid injection (than E30) in the paraventricular nucleus of the thalamus.

Paraventricular nucleus of the thalamusPrelimbic area lightnot knownPHAL
Case pg79. Soma notes An injection more caudally in the paraventricular nucleus which may involve the mediodorsal thalamic nucleus. Terminal notes Highest density of PHA-L labeled fibres in the prefrontal cortex is present in the ventral part of the prelimbic cortex. Most fibres distribute over {1,5} whereas {6,3} are labelled in order of decreasing fibre density.

Case pg76, fig3. Soma notes PHA-L was injected in the paraventricular nuc ?bilaterally. --See fig 1 for examples of inj sites, but not for every case-. The diameter of the inj sites varies from 150 to 600u. PHA-L was injected at various rostrocaudal levels of paraventricular nuc. Terminal notes In the ventral part of the prelimbic cortex, anterogradely labelled fibres form a terminal plexus that is most dense caudally. The fibres terminate predominantly in {1,5,6}. At most caudal levels of PL, fibres in {6} extend into dorsal PL.

Labeled cells were present throughout most of the anterior midline thalamus—most heavily concentrated in PV, PT, IAM, and RE (Fig. 5k, l). Collator note: Swanson Atlas Levels 24-25.
