From: Examining time–frequency mechanisms of full-fledged deep sleep development in newborns of different gestational age in the first days of their postnatal development

Figure 7

(a–c) Present the results of calculating the CWT energy, \(E\left(f,{t}_{0}\right),\) averaged in the time window Δt in different states—active wakefulness (AW), active sleep (AS) and quiet sleep (QS)—for the EEG channels O2, C4 and Fp2, respectively, recorded during the first monitoring session in a newborn # 7 from group I. The ordinate axes represent the frequencies of oscillatory activity (f, Hz), while the abscissa axes indicate time (t, s). The diagram shows a comparative time scale of 300 s. The color codes the mean amplitude of oscillatory activity, where red corresponds to the maximum value, while light yellow color depicts the minimum value.
