Changes in EEG Power Spectral Density and Cortical Connectivity in Healthy and Tetraplegic Patients during a Motor Imagery Task
Figure 1
Model of interconnected ROIs used in the present work to simulate power spectral densities in prefrontal regions during a foot-movement task. are connectivity weights, estimated from real data using the genetic algorithm described in the text. The regions CMA_L, M1F_L and _L oscillate in the beta range when stimulated with white noise. The LF region oscillates in the alpha range, whereas the HF region generates a rhythm in the gamma band (see Table 1 for parameter numerical values within the regions).
