Correlation analysis between EEG data and facial expressions and sleep behaviors

Figures & data

Figure 1. Sleep behaviors and facial expressions and EEG combine measure scheme.

Figure 2. The figure shows the alpha topographic map of the average power of each wave every 30 min. The darker the color, the stronger the power in the region, with a positive increase in red and negative increase in blue.

Figure 3. The figure show the delta topographic map of the average power of each wave every 30 min. The darker the color, the stronger the power in the region, with a positive increase in red and negative increase in blue.

Figure 4. The figure show the beta topographic map of the average power of each wave every 30 min. The darker the color, the stronger the power in the region, with a positive increase in red and negative increase in blue.

Figure 5. The figure shows the gamma topographic map of the average power of each wave every 30 min. The darker the color, the stronger the power in the region, with a positive increase in red and a negative increase in blue.

Figure 6. The figure show the theta topographic map of the average power of each wave every 30 min. The darker the color, the stronger the power in the region, with a positive increase in red and negative increase in blue.
