Figure 2

Power spectral density (PSD) plots from different gestational age groups. An example of group-averaged PSD plots taken from (a) early GA (n = 25), (b) mid-GA (n = 22), and (c) term infants (n = 4) in the During-feed period averaged between Feeding 1 and Feeding 2. X-axis is the GR frequency of EGG in cpm, and y-axis is the power spectral density in μV2/Hz. The red vertical lines mark the GR frequency bands of bradygastria (brady), normogastria (normo), and tachygastria (tachy). The error bars represent the standard error of the mean from four term infants.
