Physical characteristics of Trpm1−/− mice. a Daily activity averaging 6 days in the home cage; n = 22 for both genotypes. b Latency to the first response in the hot plate test. n = 24 for both genotypes. c, d Acoustic startle response/prepulse inhibition tests; c amplitude of the startle response to the 110 and 120 dB acoustic stimuli, d percentage of prepulse inhibition at the 74 and 78 dB prepulse sound level. n = 24 for both genotypes. *P < 0.05; repeated measures 2-way ANOVA (a), Student’s t test (b-d)
