a These data were part of our previously published study and have been revised to include only the males of the same cohort (Gatta et al., 2017). In cerebellum, similar results were obtained with 2 different set of primers targeting GABAAR α 2 subunit (see supplementary Table 2). Values are mean ± SEM of 19–20 samples per group *P < .05, **P < .01. Student’s t test vs control. α 6 mRNA levels were not detectable in the HPC in our experimental conditions (ND).
