Ongoing alpha coherence. Ongoing normalized alpha coherence during mental rotation. Top row: normalized coherence between electrode P3 and P4. Error bars and shaded areas depict SEM; asterisks code for significant differences (*<0.05). (A) Averaged normalized coherence after stimulation for stimulation and sham. (B) Averaged normalized coherence after stimulation for females and males. (C) Time-course of normalized coherence after stimulation for stimulation and sham group. Bottom row: normalized coherence between electrode P7 and P8. (D) Averaged normalized coherence after stimulation for stimulation and sham. (E) Averaged normalized coherence after stimulation for females and males. (F) Time-course of normalized coherence after stimulation for stimulation and sham group.
