1. Spectra superimposed on the brain over each electrode for patient JC during a hand movement task (red curves) and resting interval (blue curves).
Spectra superimposed on the brain over each electrode for patient JC during a hand movement task (red curves) and resting interval (blue curves). The frequency range (see top left inset) is 8–100 Hz. Note that 60 Hz noise varies across electrodes (the two chosen frequency bands are away from this artifact). The bottom cortical insets reflect the generated cortical activation maps, with the HFB map on the left cortex and the LFB map on the right. Note that, as expected by the bottom insets, the most dramatic effects in the individual spectra are seen in the top, middle portions of the grid.
