Figure 1: Frequency power in the left and right channels after the middle cerebral artery occlusion (MCAo): The 5-minute signal segment before MCAo was used as the baseline to compare the changes in frequency power at time points 0h, 4h, 8h, and 12h. The statistically significant drop in power of the frequencies is represented as red light (p=≤0.05). The green light represents no modification in the power of the brainwaves. Channels near to the MCAo (nMCAo): CH5L and CH4L; Channels far from the MCAo (fMCAo): CH3L and CH2L; ACA channel: CH1L.
