Fig. 8 — Scatterplots of the correlations between the discrimination index (DI) assessed in the novel object recognition task, and dopamine receptors. A – E: Correlation between DI and D1 receptors labelled with [³H] SCH23390 in adult CPu (A), adult GPi (B), adult SN (C), adolescent CPu (D), and adolescent GPi (E). F, G: Correlation between DI and D2 receptors labelled with [³H] Raclopride in adult CPu (F) and adult NAc core (G). H. Correlation between DI and D4 receptors labeled with [³H] YM-09151–2 in adult CPu. I: Correlation between DI and D1 receptor protein levels in adult CPu.J. Correlation between DI and D2 receptor protein levels in adult CPu. Data are the mean values of dopamine receptor binding or protein levels of adult or adolescent animals in different brain regions and the mean values of the discrimination indexes of both adult and adolescent animals for C, BMS and PMS rats (see Materials and methods). C: control; BMS: brief maternally separated; PMS: prolonged maternally separated rats. CPu: caudate-putamen; NAc core: nucleus accumbens core.
