Mu-Beta event-related (de)synchronization and EEG classification of left-right foot dorsiflexion kinaesthetic motor imagery for BCI
Fig 3
Time-frequency maps (participant 1, 2, and 4).
Common average reference channel Cz, and two bipolar channels, C3-Cz and Cz-C4, are shown. The left columns show left foot dorsiflexion kinaesthetic motor imagery (KMI), and the right columns show right foot dorsiflexion KMI. Significant (p < 0.05) band-power changes are shown during the trial period of -3 to 7 s. The pink dotted line indicates the beginning of KMI.
