摘要
Weanling male and female rats did not differ in open-field activity or rearing or in shock thresholds measured with the flinch-jump technique. Sex differences on all measures emerged by 50 days of age and persisted thereafter. Although shock thresholds were positively correlated with body weight, both age and sex affected shock thresholds independent of correlated weight differences.
