LightatNight: Light at Night for Mice

Description Format Details Source

Description

Data from an experiment with mice having different nighttime light conditions

Format

A dataset with 27 observations on the following 9 variables.

Details

In this study, 27 mice were randomly split into three groups. One group was on a normal light/dark cycle (LD), one group had bright light on all the time (LL), and one group had light during the day and dim light at night (DM). The dim light was equivalent to having a television set on in a room. The mice in darkness ate most of their food during their active (nighttime) period, matching the behavior of mice in the wild. The mice in both dim light and bright light, however, consumed more than half of their food during the well-lit rest period, when most mice are sleeping.
