Wheel-running behaviour in 12 species of muroid rodents

The objective of this research was to describe the levels and periodicity of wheel running in 12 species of muroid rodents in order that comparisons could be made among different measures of activity in a variety of species. Six males...

Nest-box choice in the laboratory mice: Preference for nest-boxes differing in design (size and/or shape) and composition

Mice had a strong preference for nest boxes which allowed visual cues to pass and which had a rectangular shape. Highest in order of preference were small narrow-sided nest-boxes, followed by small square ones, then the small circular one, and...

Endogenous opioids and social behavior

Evidence for the hypothesis that brain-opioids mediate social affect and social attachments is summarized. Opiates and opioids are very effective in reducing social separation-induced distress vocalizations (DVs), in puppies, young guinea pigs and chicks, while opiate antagonists can increase DVs....

Fear and affiliation in domesticated male rats

Unfamiliar conspecifics were just as effective in allaying fear as familiar animals. Even the individually reared rats, unused to other rats, were less fearful with conspecifics than when they were stressed alone. These findings simply attest to the strength of...

Conditioned and unconditioned influences on body temperature and ethanol hypothermia in laboratory rats

An increase in body temperature occurred in animals who's individual cages were removed from their usual position. After one hour at the new location body temperature had increased 1.3C. Movement of an entire cage rack, with the cages remaining in...
