Dampening ability by gestational age. Broadband frequency response of the autoregulatory system by gestational age at birth. The response (dampening) of the autoregulatory system is indicated on the Y-axis for discrete frequencies between 0 and 0.25 Hz. Note the increased dampening at approximately 0.1 Hz (Mayer frequency band). Infants are grouped by gestational and color coded (red-24 weeks (n=17), yellow-25 weeks (n=15), purple-26 weeks (n=19), green-27 weeks (n=5), blue-28 weeks (n=6)).
