Environmental influence on brain and behavior of year-old 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.

Reinforcing properties of spontaneous activity in the rat

Required 21 male sprague-dawley rats to bar press on an ascending sequence of fixed-ratio requirements in order to run in either a voluntary treadmill or a braked running wheel. In both testing situations the duration of the burst of running...

Circadian alteration of audiogenic seizure susceptibility in rats

Genetically determined audiogenic seizure susceptibility in Wistar albino rats showed distinct rhythmicity with its increase and decrease during night and day, respectively. This rhythmicity is apparently regulated by light since its trend can be readily reversed by artificially reversing the...

Nesting material as a reinforcer for operant behavior in the rat

Rats will readily work for the acquisition of nesting material. Paper strips serves as an adequate reinforcer. .. Prior to parturiation, only a small daily nest was built and barpressing occurred only in the dark part of the lighting cycle....

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...
