Case pg194, fig4. Soma notes retrograde labeling of cells throughout the nucleus accumbens, except for most medial psart of nucleus & in adjacent regions of caudoputamen. Terminal notes True Blue was injected into ?SI. May be taken up by fibres of passage from midbrain?Inj of TB in rostroventral tip of GP & adjacent parts of SI.

In contrast, an injection of true blue centered in the rostroventral tip of the GP and adjacent parts of the SI (see GP6 in Fig. 4) resulted in the retrograde labeling of cells throughout the nucleus accumbens, except for the most medial part of the nucleus (rostra1 to the level illustrated), and in adjacent regions of the caudoputamen.
