-
In each animal strain or cross, age did not influence immobility times in the FST and TST between the ages of 8 and 11 weeks. All the data in this table were obtained from 8- or 9-week-old animals. sd, standard deviation; n, number of animals; B6, C57BL/6; C3, C3H/He.
-
↵Significantly different (P < 0.001) between B6 and C3 strains by Bonferroni/Dunn test.
