Previous experiments using progressive-delay schedules showed that destruction of the nucleus accumbens core (AcbC) altered rats' choice between food reinforcers differing in size and delay. Application of a quantitative model of inter-temporal choice suggested that lesions of the AcbC increase the delay-dependent degradation of reinforcer value (delay discounting) without altering instantaneous reinforcer value. This experiment examined the effect of lesions of the AcbC on inter-temporal… CONTINUE READING
