Scalp topographies of channel weights according to the feature extraction for velocity decoding. (A) This figure shows the averaged scalp topographies of channel weights across five subjects in 0.1-4 Hz (left) and 4-40 Hz (right), respectively; (B) This figure shows the scalp topographies of channel weights for the five subjects in 0.1-4 Hz (upper row) and 4-40 Hz (lower row), respectively.
