Blocking dopamine D2-receptors reduced the expression of Pavlovian-conditioned alcohol-seeking in Harlan, but not Charles River rats (Experiment 2a). At test rats received presentations of the CS+ and CS− as during PDT. However, no ethanol was delivered and tests were conducted in a context where alcohol had never previously been consumed. Data represent mean (± SEM) normalized port-entries during the CS+ (filled bars) and CS− (open bars) following saline and eticlopride (5 μg/kg or 10 μg/kg) pre-treatment in a Charles River (n=16) and b Harlan (n=13) rats
