Effects of N-acetylcysteine on PPI in mGluR5+/+ and mGluR−/− mice. Percentage of PPI (a) and startle amplitude (b) at each of three prepulse levels (69, 73, and 77 dB) are presented. Data are expressed as mean ± SEM (n = 8). * p < 0.05, compared with the vehicle-treated group of the same genotype; # p < 0.05, compared with the same treatment group of wild-type mice
