Light/Dark Box Light/Dark Box

Our Light/Dark cage allows to carry out the Light/Dark Conflict Test conveniently.

The Light/Dark Box is a characteristic tool used in the assessment of anxiety: the apparatus consists of a simple chamber divided into a dark and a light compartment. Rodents prefer darker areas over light areas: however when presented in a novel environment, rodents have a tendency to explore. These two conflicting emotions lead to observable anxiety-like symptoms.

Mice are allowed to move freely between the two chambers. The number of entries into the bright chamber, the duration of time spent there and the related exploratory behaviors, detected via a videotracking system, are reliable parameters for assessing anxiolytic effects that may be useful in identifying and/or screening of anxiolytic and anxiogenic agents.

The cage is available for Mice or Rats; standard model has transparent walls on the lit compartment, but an optional model with opaque white walls is also available.

Light is not included

    The light/dark transition test was originally developed by Crawley and colleagues (Crawley and Goodwin, 1980) and subsequently validated by Costall et al (1989).

    The light/dark transition test is one of the most widely used tests to measure anxiety-like behavior in mice. The test is based on the innate aversion of rodents to brightly illuminated areas and on their spontaneous exploratory behavior in response to mild stressors, that is, novel environment and light. Time spent in the lit compartment, and the related exploratory behavior, are reliable parameters for assessing anxiolytic effects that may be useful in identifying and/or screening of anxiolytic and anxiogenic agents.

    The original apparatus consisted of a small dark safe compartment (one third) and a large illuminated aversive compartment (two thirds), while more recently other models have been validated (Takao and Miyakawa 2006) in which the size of the two chambers is the same. Another difference between the original design and other models available is that the lit compartment is made of opaque white plastic. These differences, namely the size and openness of the light chamber, allow for the simultaneous detection of bright-space anxiety as well as open-space anxiety in the original version of the test.
