Each pre-startle tone was presented for 20 ms, in a silent background 50 ms before the sound off startle (120 dB broad band noise for 50 ms).
Nrxn2α Het mice had a marginally stronger startle response to the 120-dB startle tone, although no significant differences were observed at any of the sound intensities (RM ANOVA; significant Genotype × dB intensity interaction (F(10, 320) = 2.67, p =.022); pairwise comparison failed to reveal significant differences at any sound intensity between the genotypes (all p >.05; Figure 5a).
PPI was measured by the delivery of a tone at either 70, 80, 85, and 90 (prepulse) for 10 ms followed by a 100 ms gap at background noise and then a 120 dB "startle" tone for 40 ms. Background noise at 65 dB was presented throughout the trials.
One hour following salicylate administration, ASR suppression was diminished, though only for pre-startle tones centered on a frequency of 12 kHz (11 13 kHz).
For the pASR testing, pre-startle tones were presented at 4,8,12, 16, 20, and 24 kHz at levels of 45 and 60 dB in all groups with the exception of the Noise Group: Since those animals experienced hearing loss, levels of 75 and 90 dB were used in ASR conducted post noise exposure.
Even I was startled by the tone of the Jan.
After a summer of growing backbench dismay at the coalition's flagging fortunes, ministers were startled by the tone of Tuesday's "man or mouse" challenge.
Sitting in the corner of a deserted tiki bar, save for the old Korean woman uncapping our Blue Moons, it felt like a cheap aping of every bar scene in the last season of Breaking Bad; nobody around, hushed tones, startled glances at the door as nobody came in because 3 PM on a Wednesday.
