Figure 2. Phenotype differences in CCK and CCK-2R 35S-mRNA hybridization signal.
Autoradiograms illustrate 35S-mRNA hybridization signal for CCK (A, B, C and D) and for CCK-2R (E, F) in selected coronal sections of the brain. Abbreviations: DG, dentate gyrus; Hipp, hippocampus; mPFC, medial prefrontal cortex; PFC, prefrontal cortex; VTA, ventral tegmental area.
