Peak activity is commonly reported from afternoon to evening and a ‘sleep–wake cycle’ where movements are absent for 20–40 minutes is deemed normal although episodes rarely exceed 90 minutes in a healthy fetus. Potential factors that can alter patient perception to fetal movements include small...
Many pregnant women notice that their babies are more active at certain times of the day, for instance, particularly in the third trimester as the fetus begins adapting to a more regular sleep-wake cycle. The mother’s nutrition, hydration, and stress level can also play a part. It is ...
This study used maternal鈥揻etal Holter monitor which is based on the technology of fetal electrocardiograph (FECG) to collect the FHR, and then design algorithm to extract the baseline FHR, acceleration, variation, sleep-wake cycle and nonlinear parameters. There were significant differences in the...
This suggests that endothelial-derived PG could act on signal transduction pathways within the CNS, leading to the febrile response (10), changes of the sleep-wake cycle, and activation of the autonomic nervous system and hypothalamo- pituitary-adrenal axis (11). COX-1 and COX-2 are the ...
Thus fetal cognitive motor activity, including auditory discrimination, orienting, the wake–sleep cycle, FHRs, and defensive reactions, appear to be under the reflexive control of the brainstem, which also appears capable of learning-related activity.R. Joseph...

oxygenation status (eg, prematurity, fetal sleep–wake cycle, maternal medication exposure, maternal smok- ing, and fetal central nervous system abnormalities) can adversely affect biophysical parameters (8, 9). Antepartum Fetal Surveillance Techniques ...
Likewise, the maintenance of a regular maternal light/dark and sleep/wake cycle is important to stabilize circadian rhythms generated by the maternal central circadian pacemaker, the suprachiasmatic nuclei. Optimal circadian rhythmicity in the mother is important since her circadian clock, either directly...
We aim to reveal patterns of association among sleep-wake behaviors that are challenging in the life of children with fetal alcohol spectrum disorders (FASD).Spruyt, KarenIpsiroglu, OsmanStockler, SylviaReynolds, James N.Vrije Univ Brussel Fac Psychol &International Journal of Developmental ...
Neurogenesis is governed by numerous genes which regulate transcription, cell cycle progression, centrosome maturation (MCPH1, CENPJ, CDK5RAP2) [15], dynein binding, centrosome duplication (NDE1) [16], DNA repair (MCPH1 [15], PNKP [17], and PCNT [18]), proliferative ability of the neural...
