Figure 1.
Shuttle-box behavior during the adolescent period. Means and SEM are represented. (A) Number of avoidance and escape responses in CST rats (n = 56). (B) Number of inter-crossings during the 5 min habituation previous to each shuttle-box session in CST and UST (n = 58) rats. ++p < 0.01, +++p < 0.001 versus UST rats. (C) Time (%) spent freezing during the habituation period of sessions 2 and 8 in a sub-set CST and UST rats (n = 46–47/group). The effect of time is not represented.
