Dominant frequency band partition. (a) An example of minute-dependent dominant frequency band partition map across a time period (0–40 min). X-axis denotes the time in minutes; Y-axis represents three EGG rhythm frequency bands in cycles per minute (cpm). Red boxes indicate the dominant frequency band for each minute. (b) A flow chart of the procedure to calculate the % time spent in each GR band for each chosen time period.
