Coordinates are expressed as the lateral (x), anterior (y), and superior (x) distances from the midcommissural point. Note that two sets of coordinates are provided because each ECoG signal was recorded from a pair of electrodes that were bipolar referenced.
b
Note, part-way through the Nexus D3 run the lower limit was adjusted to 1.5 V. The lower limit was still 1 V for Nexus E.
