[Analysis of sexual differences in emotional reactions in rats].
The effect of sex differences on the emotional reactivity in the rat (Rattus norvegicus) has been analyzed by means of the open field test and the acquisition of a conditioned emotional response (C.E.R.), according to Estes and Skinner technique. The combined use of C.E.R. and defecation rate techniques shows that males present a higher emotional reactivity than females. Furthermore estrous cycle affected female ambulation rates in open field.
