Experimental Paradigm

 

Triggered Averaging

Graphs: Two examples of the triggered averaging process.  For each example, the top 5 graphs show ECoG corresponding to individual movements.  Signal patterns related to the movement are hard to see in this ECoG.  The both graph for each example shows a fairly clear signal pattern related to the action.

Triggered ECoG Averages

A mri of a brain with electrode locations shown by @ signs over large portions of the temporal and parietal lobes.  A box zooms out from the parietal electrode grid showing ECoG averages for 32 electrode locations during a pinch movement.  Averages with activity related to the movement are clustered in one corner of the electrode grid.
