Source localization during tactile stimulation and imagery of the upper limbs

In this study we present the results of mu range event-related desynchronization/synchronization (ERD/S) source estimations. ERD was provoked by tactile stimulation (TS) or tactile imagery (TI), the electroencephalography (EEG) data were acquired with the high-density EEG (hdEEG), and the inverse pr...

Description
Summary:	In this study we present the results of mu range event-related desynchronization/synchronization (ERD/S) source estimations. ERD was provoked by tactile stimulation (TS) or tactile imagery (TI), the electroencephalography (EEG) data were acquired with the high-density EEG (hdEEG), and the inverse problem was solved by using the sLORETA method. The results of source estimation have shown that both TS and TI lead to significant mu range ERD with its sources localized in sensorimotor cortex, which points to that tactile imagery shares the neuronal substrate of tactile perception.
