Nucleus accumbens lesions reduce amphetamine hyperthermia but not hyperactivity.

Electrolytic lesions of the nucleus accumbens were found to produce an increase in spontaneous locomotion; additionally, these lesions attenuated the hyperthermic, but not the hyperkinetic, actions of d-amphetamine. These results suggest that while dopamine release from the mesolimbic system may underlie amphetamine-induced hyperthermia, other structures must also be involved in amphetamine-induced hypermotility.
