Startle responses (means ± SEM) in the noise burst intensity function test with 20 ms startle stimuli of 100, 105, and 110 dB (A), immobility time in the FST for 6 min (B), and BDNF protein concentrations in homogenates of the hippocampus (C) of male WT mice (n = 4), female WT mice (n = 13), male GSK mice (n = 10), and female GSK mice (n = 11). †p < 0.05 and ††p < 0.01 (overall sex effect); **p < 0.01 (overall genotype effect).
