Figure 4.

Motor execution single subject plots of two exemplary subjects (A,B) of Δ[HbO] and Δ[HbR] data. The subplots in the left column contain epoched ([−5, 30] s) and baseline corrected ([−5, 0] s) data of a single ME trials preprocessed by BPF and BPF+GCR approaches (BPF vs. BPF+GCR) and the subplots in the right column contain the data preprocessed by means of WLF and WLF+GCR approaches and the GC itself (WLF vs. WLF+GCR). For each subject, the first row contains the pre-test and the second row the post-test ME data.
