Selective Enhancement of Motor Imagery Features Using Transcranial Direct Current Stimulation
Transcranial Direct Current Stimulation (tDCS) has been shown to selectively modulate cortical responses in memory, motor and perceptual tasks. Here we show that this type of stimulation results in targeted enhancement of brain patterns elicited during motor-imagery. Offline analysis suggest this may yield higher classification performance. Experiments with healthy subjects (N = 10) and patients with spinal cord injury (N = 9) supports the idea of using tDCS as a facilitator for using brain-computer interfacing (BCI) in the frame of motor rehabilitation.
