Fig. 6. Aged Animals Have Significant Reduction in Global Node Degree.
A. Group average map of global (whole cortex) node degree in the delta frequency range (1–4 Hz) for young (top) and aged (middle) animals. The bottom map represents the difference between young and aged animals in global node degree thresholded for significance. B. Group average map of global (whole cortex) node degree in the infraslow frequency range (0.01–0.2 Hz) for young (top) and aged (middle) animals. The bottom map represents the difference between young and aged animals in global node degree thresholded for significance.
