Figure 7

Optical self-stimulation of the VTA-NAc shell pathways. A. All TG rats self-stimulated more than the Non-TG Cocaine group (*p<0.0001). Rats in the TG Cocaine Rostral exhibited greater self-stimulation compared to TG Cocaine Caudal rats (#p<0.05). B. An inverse correlation was found between the amount of aversive taste-reactivity exhibited on day 7 and self-stimulation rewards received on day 3. Rats with placements in the rostral and caudal shell are represented by closed circles and open triangles, respectively.
