No differences were observed in baseline ERO mean energy in the frontal delta and theta bands between B6 and D2 mice (Supplementary table 2). In contrast, baseline ERO mean energy in the frontal alpha/beta band was lower in B6 than in D2 mice in response to standard and rare tones (Supplementary table 2). Baseline ERO energy in the parietal delta, theta and alpha/beta bands was lower in B6 than in D2 mice in response to standard tones. Lower baseline ERO energy in the parietal theta and alpha/beta bands was also observed in B6 mice in response to rare tones and in the parietal theta band in response to noise tones (Supplementary table 2).
