(A) DA Effects of ethanol and subjective response. In all subjects (n = 26), self-reported intoxication correlated with increased displacement of [11C]raclopride (ΔBPND) to ethanol with beer flavor in L NAcc, as illustrated in Fig 3A; rho = 0.399, p = 0.044. The dashed line indicates unchanged ΔBPND. (B) Laterality. Mean reduction in BPND in response to ethanol and beer flavor (shown in Figs 3A,B) showed a lateralized response, as compared to the homologous region. Columns and spatial extent of responding regions shown in (hatched) yellow, with homologous regions (coronal view, below) indicated in cyan. *p < 0.05, †p = 0.057
