    Abstract:
    A week salt load and partial water deprivation of rats lead to disturbance of conditioned activity: decrease of adequate runs to the feeder with salted food and disinhibition of differentiations. In cases of shift of insipid signal to the feeder with salted food the animal ate alimentary reinforcement of such a degree of salinity which was rejected by the animal at realization of run in response to the salt signal. Against the background of thirst a trans-switching of signal role of the conditioned signals was performed in accordance with the new quality of the alimentary reinforcement (the feeders changed their places). The role is discussed of the external and internal signalization in regulation of gustatory thresholds and participation of the lateral hypothalamus in these mechanisms.
