INFLUENCE OF ANOSMIA AND ABLATION OF WHIS KERS ON THE BEHAVIOR OF NORWAY RATS (RATTUS-NORVEGICUS) IN EXPERIMENTAL CONDITIONS

The study of behavior of Norway rats was carried out in a chamber with optical border. Whiskeral taction and olfaction were inactivated in t urn. The rats with ablated whiskers used optic orientation to greater degree than intact ones or animals with inactivated olfaction. This is supported by a lot of indices, in the first place, the index of orien tation by whiskeral taction. Probably, whiskeral taction and vision ar e equivalent sources of external information more significant than olf action. The sex differences in behavior of both sensory deprived and i ntact rats orientating in the experimental chamber were noted. The sex differences of the index of orientation by whiskeral taction were obs erved only in animals with anosmia after the ablation of whiskers.
