Self-sustaining activities and reinforcement in the nest building behaviour of mice

Mice will readily work in order to get nesting material. It is concluded that gathering is at least to some extent authonomously controlled, and that it is a weak positive reinforcer.

Cage size as a factor in environmental enrichment

Cage size significantly affected 38-day gross body weight, open-field activity and defecation, running-wheel activity, exploration, and water consumption. .. Rearing in large cages, either wire or Plexiglas, appears to reduce emotionality... The results of this experiment indicate that cage size...

Effects of clean and soiled sawdust substrates and of different urine types upon aggressive behaviour in male mice

Greatest levels of aggression were found in cages that had ungergone incomplete cleaning, such as renewal of substrate only.

Effects of age at differential housing and the duration of individual housing/grouping on intermale fighting behavior and adrenocortical activity in TO strain mice

When the mice were subjected to stress (e.g., open field exposure) corticosterone levels in single-housed subjects were consistently higher than in group-housed subjects.

Effects of the duration of individual or group housing on behavioral and adrenocortical reactivity in male mice

Basal corticosterone levels did not show a significant difference between single-housed and group-housed animals. When the mice were subjected to stress (e.g., open field exposure) corticosterone levels in single-housed subjects were consistently higher than in group-housed subjects, indicating an increased...

Drug-modulated behavioural responses to environmental enrichment

The home-cage activity of mice housed in either social or enriched sensory environments was continuously recorded for 23 days. During this period the mice were given daily injections of either strychnine, chlorpromazine, or saline. Both chlorpromazine and social rearing depressed...
