Abstract
Our goal was to investigate the relationship between fetal behavioral states (fBS) and noninvasive recording of fetal auditory and visual evoked responses (AER, VER). AER, VER and No-Stimulus (NS) data were recorded using a 151- channel SARA system. Interfering cardiac signals were removed and fBS was determined according to Nijhuis criteria for each recording and classified into quiet, active and transition states. AER and VER were scored for presence of an evoked response (ER). We observed that with increased gestational age (GA), the incidence of quiet sleep state decreases whereas the transition state increases and pure tone auditory and visual stimulation does not influence the fetus sufficiently to cause a shift in states. On the other hand, the presence of fetal ER to auditory and visual stimulus is closely related to the given fBS.
