Description

Time in darkness for mice in different environments

Format

A data frame with 14 observations on the following 2 variables.

• Time Time spent in darkness (in seconds)
• Environment Type of environment: Enriched or Standard

Source

Data approximated from summary statistics in: Lehmann and Herkenham, "Environmental Enrichment Confers Stress Resiliency to Social Defeat through an Infralimbic Cortex-Dependent Neuroanatomical Pathway", The Journal of Neuroscience, April 20, 2011, 31(16):61596173.

Details

In the recent study, mice were randomly assigned to either an enriched environment where there was an exercise wheel available, or a standard environment with no exercise options. After three weeks in the specified environment, for five minutes a day for two weeks, the mice were each exposed to a "mouse bully" - a mouse who was very strong, aggressive, and territorial. one measure of mouse anxiety is amount of time hiding in a dark compartment, with mice who are more anxious spending more time in darkness. The amount of time spent in darkness is recorded for each of the mice.
