From: Decoding hand movement velocity from electroencephalogram signals during a drawing task
Decoding performance of different bands. By using the features from different frequency bands respectively, we show the mean and SEM of the Pearson correlation coefficients (CCs) between measured and decoded hand velocities across cross-validation folds for each subject in x-dimension (blue) and y-dimension (red). Stars indicate the bars with significant CCs (p < 0.05 for no correlation hypothesis, Student's t-test). The average CCs across subjects for each band feature are also given.
