Studies have examined delay discounting in rats and mice bred for different levels of alcohol consumption. Rats bred for high alcohol consumption showed a stronger tendency to devalue delayed rewards compared to those bred for low alcohol consumption. Similarly, mice with alcohol preference also exhibited higher levels of discounting. Another study investigated delay discounting and response patterns in mice bred for varying alcohol consumption. Additionally, rats with induced neuron loss in the basal forebrain displayed increased alcohol consumption, which was associated with heightened aggression, reduced sensitivity to punishment, and a lack of attention to future rewards.
