Sex differences in locomotor activity after acute and chronic cocaine administration
Adult, intact and gonadectomized male and female Wistar rats (n = 9) were exposed to an automated open field to assess the behavioral effects of acute cocaine administration (saline, 1.0 and 10.0Expand

Behavioral differences between male and female rats: Effects of gonadal hormones on learning and memory
The organizational, activational and reorganizational effects of gonadal hormones have been extensively investigated with respect to sexual, aggressive and maternal behavior. It has thus beenExpand

Delayed spatial response alternation: Effects of delay-interval duration and lesions of the medial prefrontal cortex on response accuracy of male and female Wistar rats
A delayed spatial response alternation procedure was used to assess behavioural differences between male and female Wistar rats, assumed to involve memory functioning. In Expt. I, subjects wereExpand

Sex- and time-dependent changes in neurochemical and hormonal variables induced by predictable and unpredictable footshock
Previous experiments have revealed sex-dependent effects of inescapable shock in rats. Behavior of male rats was more severely disrupted by inescapable shock than behavior of female rats. These sexExpand

Cocaine-induced conditioned taste aversions in male and female Wistar rats
After an initial period of adaptation to 20 min per day of limited water availability, male and female Wistar rats were allowed access to water or a 0.1% sodium-saccharin solution. SaccharinExpand

Sex-dependent effects of inescapable shock administration on behavior and subsequent escape performance in rats
Stress-induced behavioral disturbances have widely been used as animal models of depression. Sex differences, however, have rarely been studied, even though evidence is available to show that malesExpand

The behavior of male and female Wistar rats pressing a lever for food is not affected by sex differences in food motivation
Abstract Male rats both eat more and weigh more than females. Differences in food intake and body weight result, at least partly, from differences in gonadal hormone secretions. The presentExpand
