ON THE AGE-DIFFERENCES OF THE BEHAVIOR OF NORWAY RATS (RATTUS-NORVEGICUS) WITH ABLATED WHISKERS

A comparative study of behavioral age differences of rats was carried out in an experimental chamber with optic border. The ablation of whis kers and olfactic deprivation caused decrease of motility and the crit erion of whiskeral sensibility, which was more in younger animals than in adults. Thus, the younger rats are more ivulnerable to the loss of whiskers and olfaction. The criterion of whiskeral sensibility was hi gher in adult rats than in younger ones throughout the experimental pe riod. This fact can be evidence of more pronounced at the age of 2 to 3 months optic orientatioun. The sex differences of the behaviour were not detected in younger rats.
