Effects of illumination on wall-leaving behavior and activity in three inbred mouse strains

The results clearly indicated that illumination levels is an important variable affecting the general activity of mice. The animals showed less fearfulness and emotionality under low illumination conditions.

Effects of diet and type of nesting material on the reproduction and lactation of the rat

Reproductive improvements due to paper nesting material were dramatic. The 10.8 pups per litter weaned by mothers nested in paper was very significantly higher than the 7.0 pups weaned by those with wood shaving. A more sensitive measure of the...

Adrenocortical response to novelty and noxious stimulation

It was found in rats that the magnitude of the stress response to being transferred into an experimental cage is virtually the same as that produced by electrical shock. ... Exposure to a new environment, or novelty, may contribute significantly...
