[Formation of taste aversions in the rat]

The presence of correlation between the initial attitude of animals to a certain taste agent and the intensity of conditioned taste aversion (CTA) after LiCl poisoning was studied in nonlineal male white rats. 4 types of behavioural reactions were revealed: 1) the nonspecific inhibitory reaction to the situation in which CTA was elaborated; 2) specific associative-adaptive connection of CTA with the taste agent used (0,1% saccharine solution); 3) complex reaction consisting of the two first ones; 4) the same drinking behaviour as that before CTA elaboration. Moreover, a correlation was found between the initial attitude of animals to certain taste agent and the intensity of CTA after pairing of this agent with subsequent poisoning.
