How an internal clock gene can alter innate behaviors in mice

Posted by G. Smit on Jul 24, 2014

Some might argue that laboratory mice are not the same as wild mice, yet they remain capable of performing the innate, routine behaviors necessary to survive in natural environments, such as courtship, nest-building, and exploratory activities. Still, their ‘non-natural’ (read: laboratory) environment may limit them in the expression of these behaviors, something we recently addressed in these blog posts.

Circadian rhythmicity

The internal circadian clock is of fundamental importance for animals to anticipate recurring events and ensuring basic behaviors, such as  gathering food and building a nest, occur in time. One of the ways we influence the animal’s natural capacity to perform these and other innate behaviors is by altering the light/dark cycle in a laboratory setting.
