    Using Partial Directed Coherence to Study Alpha-Band Effective Brain Networks during a Visuospatial Attention Task
  7. 67
    “…We evaluated the performance of three variables to detect CD (MoCA < 25 points): age, Propofol requirement to induce unconsciousness (TCI at SEF(95): 8–13 Hz) and the frontal alpha band power (AP at SEF(95): 8–13 Hz). Results: The 17 patients (40%) with CD were significantly older (p < 0.001), had lower TCI (p < 0.001), and AP (p < 0.001). …”
