Scalp topography of power spectra changes of the EEG (relative to baseline from −1 to −0.6 s) averaged across all trials and participants. Javier M.

Frequency in ordinate from 0 to 50 Hz at a resolution of 2 Hz. Movement onset occurs at s (solid black line in all graphs). Sensors above the contralateral and ipsilateral motor areas revealed a power increase in the slow wave range (4)Hz and a de-synchronization in the (8-12)Hz and (14-30)Hz frequency bands. Graph at the right lower corner represents the average across-sensors relative power spectra changes of the recorded EEG.</p> 2013-04-17 01:18:44 Anatomy and physiology Musculoskeletal system robotics Neurological system Motor systems electrophysiology biotechnology Bioengineering Biomedical Engineering Computational biology Biological data management computational neuroscience neuroscience signal processing topography spectra eeg baseline averaged trials
