Figure 4
Induced alpha power (total power minus stimulus-locked power) of the sighted group. Time-frequency representation of the electrode showing the largest interaction between posture and attention (marked with an asterisk * in Fig. 3A) with uncrossed (a,b) and crossed hands (d,e) following attended (a,d) and unattended (b,e) stimuli. Unmasked areas in (c,f,g,h,i) indicate statistically significant differences, as identified with cluster-based permutation testing at p < 0.05, between attention conditions with uncrossed (c) and crossed hands (f), between posture conditions following attended (g) and unattended stimuli (h), and a statistically significant interaction between posture and attention (i) Note, the figure is arranged identically to Fig. 3B, which depicts total power, so that the two figures can be compared directly.
