摘要：
The effect of home cage conspecifics' behavior on locomotor sensitization to amphetamine (AMP) or ethanol (ETOH) were investigated. Female mice were repeatedly treated with saline or AMP (2.0 mg/kg for 13 days - Experiment 1) or saline or ETOH (1.8 g/kg for 21 days - Experiment 2) in home cages where all the animals had the same treatment (homogeneous home cages - HOM-HC) or in home cages where half of the animals were drug-treated and half of them were saline-treated (heterogeneous home cages - HET-HQ. Behavioral sensitization was evaluated by the quantification of open-field locomotor activity after AMP or ETOH challenge injection, respectively. In both experiments, behavioral sensitization was potentiated in HOM-HC maintained animals. These results suggest that the behavioral sensitization phenomenon can be modified by home cage conspecifics' behavior. (c) 2006 Elsevier Inc. All rights reserved.
