The Influence of Early Handling on the Temporal Sequence of Activity and Exploratory Behaviour in the Rat (Ph.D. Thesis)

Gentle handling during infancy makes rats less fearful, quasi tame in situations in which control rats remain timidly crouched at the back of the cage.

Chronic noise stress and insulin secretion in male rats

The effect of chronic noise, followed by acute noise and forced swimming, on basal glucose and insulin levels was studied in adult male rats. Chronic noise did not modify basal levels of either measured variable before or after the exposure...

Effects of aging and housing in an enriched environment on sleep-wake patterns in rats

Rats housed in enriched versus barren cages show brain changes indicative of enhanced cerebral activity, and they spend more time sleeping.
