Restorative Plasticity in the Behaviour of the Mutant Mouse Staggerer
The mutant does not rise on his hindiegs, cannot eat solid food and does not build nests. To compensate for these behaviour deficits, special arrangements were made in the cage. The mutant has a faulty body temperature regulation and was therefore provided shelters made out of a thermoinsulating material. The shelters permitted the entrance of only one individual at a time, thus giving the animal an opportunity to escape aggressive encounters with normal mice, thus improving the social life of the staggerer. Under these environmental conditions the mutant can live a fairly normal life until old age.
