Abstract
To evaluate several cognitive parameters during the execution of behavioral tasks assessing cognitive function in laboratory animals, the parameters are reported within a range. This situation entails that each laboratory must establish the conditions under which the behavioral task to evaluate the cognitive function can be carried out. C57BL/6 and BALB/c inbred strains are used more often in behavioral studies relating to anxiety, stress, fear and cognitive function. The aim of this work was to compare the behavioral response of mice of the strains BALB/c and C57BL/6 to evaluate memory and learning as cognitive functions. Young male mice, 7-8 weeks of age, from each strain were used. Y maze, object recognition and passive avoidance tasks were performed. Both strains of mice showed differences in the response to the passive avoidance and Y maze task. This study advances knowledge about the baseline behavior of laboratory mice strains and their response during the experimental procedures, which are due to the treatment, genetic influence, procedural differences, genetic background variance, or any combination of these elements.
