Chunk #22 — RESULTS — ERO mean energy and phase locking in B6 and D2 mice — ERO differences between B6 and D2 mice: ERO energy in the 50–350 ms window — ERO Energy
Group × Tone interaction in the theta band was not significant in the frontal and parietal cortices. In contrast, significant Group × Tone interaction was found in the alpha/beta band in the frontal and parietal cortices [frontal: F(1.8, 116.6) = 22.6; P < 0.001; parietal: F(1.8, 112.6) = 10.7; P < 0.001]. Post hoc assessment revealed that B6 mice had lower ERO energy in the frontal alpha/beta band in response to standard [F(1,65) = 16.7; P < 0.001] and rare [F(1,65) = 9.7; P < 0.005] tones (Fig. 3C). In contrast, post hoc analyses revealed no significant differences in parietal alpha/beta band ERO energy between B6 and D2 mice (Fig. 3D). Figure 1A–D illustrates grand-averaged ERO time-frequency representations of the rare tones for the delta (c: parietal cortex) and alpha/beta (d: frontal cortex) frequency bands.
