The effect of environment on the changes in calmodulin in rat brain produced by repeated amphetamine treatment.
Rats were given repeated infusions of i.v. amphetamine in association with placement in a novel test environment, a protocol that produces behavioral sensitization, or in the home cage, a protocol that fails to induce sensitization. In several brain areas amphetamine altered calmodulin content, but only in the group treated in a novel environment, suggesting that amphetamine-induced alterations in calmodulin may occur only when drug treatments induce behavioral sensitization.
