Relationships between fetal brain development and maternal state on stress: Using an original system for recording fetal movement

胎儿运动是胎儿健康的生物学指标，被认为是神经发育的一个指标。在本研究中，我们研究了胎儿神经发育的过程，使用原始系统来记录和分析胎儿在长期的运动。11名孕妇在日常生活条件下参与了这项研究。结果表明：24 ~ 32周胎动次数随个体发育差异而增加，36周胎动次数减少。胎儿运动开始于妊娠28周。这项研究继续对处于压力条件下的孕妇进行。

Fetal movement which is a biological indicator of fetal well-being is thought to become an index of neurological development. In the present study, we examined to demonstrate a process of fetal neurological development using an original system for recording and analyzing fetal movement during long term.Eleven pregnant women under daily life conditions participated in the study. At the results, number of fetal movement from gestational 24 to 32 weeks increased with individual differences on development, and decreased at gestational 36 weeks. Ultradian rest-activity rhythm of fetal movement started in gestational 28 weeks. This study continues for a pregnant woman under stressful conditions.
