Exposure to WN, but not 100 kHz US, conditioned with foot shock, increases the freezing response. (a and b) Experimental design. Rats were randomly divided into a no-sound group (n = 6), WN group (n = 6), and 100 kHz US group (n = 6). Twenty-four hours after the conditioning session (a), a fear memory conditioned with tones was tested in a different context (test session; b). (c) Freezing time of rats during the tone in the test session. CV = 1.12, 0.33, 0.29, and 1.11 from left column to right. All results are presented as mean ± standard error of the mean (SEM). *P < 0.05 by one-way ANOVA with post hoc Holm–Sidak multiple comparison tests.
