Ethanol (EtOH)-induced behavioral sensitization (EIBS) is defined as an enhancement of locomotor activity following repeated EtOH exposure and is proposed to reflect an increase in EtOH “wanting”. However, the reliability of the sensitization model in studying addiction is still a matter of debate. One major criticism is that the increase in locomotion occurring during sensitization may be a by-product of tolerance to the ataxic and/or sedative effects of EtOH. We investigated the relationship between EIBS amplitude and sensitivity to EtOH-induced ataxia and sedation after the development of tolerance to EtOH depressant effects in adult female DBA/2J mice. After receiving daily injection of saline or 2 g/kg EtOH during 10 consecutive days to induce EIBS, recovery from acute motor incoordination produced by ethanol (2 g/kg EtOH using rotaro.. View More»
