CONDITIONED PLACE PREFERENCE FOR ETHANOL AND INDIVIDUAL-DIFFERENCES IN RATS

The present study is an attempt to find evidence of ethanol's rewarding capabilities as measured by the conditioned place preference paradigm with regard to individual differences in emotionality and activity (measured by the open field and holeboard tests) in male Wistar rats, using a chronic and oral self-administration of the drug. Although the drug was not reinforcing for all the subjects, the results suggest a positive relation between ethanol's rewarding capability and high levels of defecation (emotionality) and low levels of rearings in the open field (activity).
