title: [The Manifestation of the Anxiety during Fear Conditioning in Wistar Rats].
abstract: In order to identify the correlation between anxiety and conditioned fear, the behavior of the same male Wistar rats was compared in three anxiety tests (open field, light-dark box and elevated plus-maze) and in Pavlovian auditory fear conditioning paradigm using correlation, factor and variance analyses. The correlation between anxiety/bravery and locomotion indexes in different tests was not revealed. Positive correlations between grooming, urinations and defecations, rearing in three tests were revealed. These data suggest that animals reacted to various tests differently, resulting, apparently in the emergence of different anxiety levels, specific for each test. Vegetative reactions, inclination to exploration and substituting behavior were more stable characteristics of rats. Anxiety behavior in elevated plus-maze correlated to freezing response to context after fear conditioning, while high-anxiety rats had higher level of freezing to context than low-anxiety rats. The higher freezing response to sound after fear conditioning was found in rats with middle locomotor activity in open field. Conditioned fear to the context and to the sound was associated with different forms of rat anxiety during different tests.
