Figure 4From: An approach to improve the performance of subject-independent BCIs-based on motor imagery allocating subjects by gender Male patient CT image and averaged TFRs. a) Representative image of the male patient’s CT (Computed Tomography). The black arrow indicates the location of the residual injury. b) Average TFR for left and right hand (affected limb) motor imagery in 8 Hz to 25 Hz from 1 s to 7 s. The dashed line at 3 seconds indicates the motor imagery onset. The black circles highlight the generated ERD.Back to article page
