“…All instances of exclusion in this sample due to fetal head position causing visual stimuli presentation to become unviable, co-occurred with poor image resolution. Twenty-nine were excluded at the coding stage as these fetuses indicated a lack of eye or body movements throughout the scanning period and appeared to be in a deep sleep state, otherwise referred to as behavioral state 1F [33].…”

“…Thus the study of activity patterns in utero has established the existence of fetal behavioral states with similarities to postnatal sleep state. Well-defined behavioral states in the human fetus in late pregnancy were described by Nijhuis et al 2 that depict four fetal behavioral states, with fetal behavioral state 1F (quiet sleep) and 2F (active sleep) being most prevalent. The latter phase is characterized by gross body movements and rapid eye movement-like eye motions thus constituting an energy-consuming fetal behavioral state.…”

“…Behavioural states analysis was carried out by means of a computerized system (Digital PDF 11) that allowed the recording of several fetal variables including heart rate (FHR), gross body movements (FM), eye movements (FEM) and breathing movements (FBM). FHR was classified in four different patterns (FHRP) according to NIJHUIS et al [10]; fetal movements were automatically synchronized with FHR and grouped for each FHRP. Several quantitative parameters (i.e.…”

“…At the end of the recordings an offline analysis of the FHR was performed using a three-minute moving window. As previously reported FHR was classified into four patterns (A to D) according to NIJHUIS et al [10]: -Fetal heart rate pattern (FHRP) A: Heart rate stable with a variability of less than 10 bpm. Isolated accelerations are strictly related to movements.…”
