Changes in EEG Power Spectral Density and Cortical Connectivity in Healthy and Tetraplegic Patients during a Motor Imagery Task
Figure 3
Comparison between real (dashed line) and simulated (continuous line) power spectral densities in the three regions M1F_L (primary motor cortex), _L (supplementary motor cortex), and CMA_L (cingulate cortex) of the left hemisphere during execution of the foot imagery motor task. The left panels refer to two healthy subjects, while the right panels refer to two tetraplegic patients. All spectra are normalized to have unitary area in the range 6–50 Hz. The value of the fitting coefficient (ranging between and ) is shown above each panel.
