From: Cortical reorganization to improve dynamic balance control with error amplification feedback
The pooled topological spectral mapping of scalp EEG at theta (4–7 Hz), alpha (8–12 Hz) and beta bands (13–35 Hz) in the EA and RE conditions. Oscillatory waves in the theta and alpha bands are most evident in the mid-frontal (Fz and FCz) and occipital (O1, O2, and Oz) areas, respectively. Beta oscillation is most evident in the left temporal (T3, TP7, and T5), right temporal (T4, TP8, and T6) and prefrontal (FP1 and FP2) areas. The mean relative power of each sub-band in the target regions is contrasted between the EA and RE conditions. There were significant EA-induced differences in pooled mid-fontal theta, pooled occipital alpha, and pooled left temporal beta oscillations (p < .05). (EA: error amplification; RE: real error)
