The use of transcranial direct current stimulation (tDCS) has been related to the improvement motor and learning tasks. research studies effects an asymmetric tDCS setup over brain connectivity, when subject is performing a imagery (MI) task during five consecutive days. A brain–computer interface (BCI) based on electroencephalography simulated in offline analysis study effect that different electrode configurations for BCI. This way, BCI performance used as validation index by classifier accuracy experimental sessions. In addition, relationship between connectivity analyzed. Results indicate group, comparison placebo sham shows higher significant number interactions electrodes MI tasks increasing However, does not improve intended hemisphere.
