Interaction of environmental enrichment and genotype

Assessed the effects of exposure to an enriched environment, from birth-38 days of age, using 3 behavioral tests: open field, exploration, and running wheels. 144 inbred mice from 3 strains (A/J, C3H/HeJ, and C57BL/10J) were used as Ss in a...

Genetic differences influencing behavioural temperature regulation in small mammals: I. Nesting by Mus musculus

When nest material is placed on the cage lid, mice will readily pull it into the cage and build a nest.

Hair-nibbling and whisker-trimming as indicators of social hierarchy in mice

Barbering is a common abnormal behavior in laboratory mice. Alopecia and loss of facial hair, as well as loss of vibrissae, seem to be a physical indiaction of social dominance.

The influence of strain and environmental factors upon feather pecking and cannibalism in fowls

Feather pecking occurs much more often when chicken are kept on wire floor rather then litter which allows the hens to peck up additional food particles.

Free and operant feeding in domestic fowls

Chicken will work for food in the presence of free identical food. It is interesting that we failed to note any clear influence exerted by hunger motivation.

The effects of cage environment upon avoidance responding in aged rats

The beneficial effects of environmental enrichment are not restricted to a brief cricial period in development. Positive effects occur also in rats aged 300 days when first placed in an enriched environment.

Effects of environmental enrichment and impoverishment on rat cerebral cortex

The first part of this paper deals with rat brain anatomy as affected by variations of starting age and of duration of exposure to enriched (complex) or impoverished (restricted) environmental conditions. Cerebral cortical depth measurements and weights of brain samples...
