Social factors and resistance to malaria in the mouse: Effects of group vs

Mortality rate of malaria-infected mice was related to number of animals per cage, population sizes ranging from 1 to 20. This was independent of age, sex, and number of animals per cage infected. Individually housed mice died as fast as...

Effects of postweaning enrichment and isolation upon emotionality and brain weight in the mouse

At weaning (21 days) 60 male C57BL/6J mice were placed into isolation cages while 60 others were grouped in enriched environments. Fifteen days later half of each group was shifted to the opposite housing condition while the other half continued...

Effects of enriched environment upon hoarding

95 mice from 2 inbred strains were exposed to a postweaning enriched environment or to a standard environment. The design allowed assessment of effects due to environment, genotype, and genotype * environment interactions. Environment enrichment differentially affected hoarding performance in...

Brain weight increases resulting from environmental enrichment: a directional dominance in mice

Sets of our male and sets of four female C3HxBALB hybrid mice were raised in (1) small standard cages [280 cm2] that were barren, vs.(2) large test cages [1375 cm2] that were barren, vs.(3) large test cages [1375 cm2] that...

Experimental modification of brain weight and behavior in mice: An enrichment study

The effects of environmental enrichment and isolation on cortical weight and learning ability were measured in mice from lines selectively bred for high and low brain weight and from an unselected control line from the same foundation population. Animals from...

Biological significance, genetics and evolutionary origin of variability in behaviour within and between inbred strains of mice (Mus musculus)

The biological significance, the origin and the genetical causation of differences in behaviour between inbred strains of mice have been studied. Three inbred strains with different origins were used, these were CPBs (Balb), CBA and C57Black. Exploratory behaviour, nestbuilding behaviour...

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...
