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

胎动是胎儿健康的生物指标，被认为是神经发育的指标。在本研究中，我们研究，以证明一个过程中的胎儿神经系统的发展，使用一个原始的系统，记录和分析胎动在长期的。11名孕妇在日常生活条件下参加了这项研究。 结果显示，孕24 ~ 32周胎动次数随发育的个体差异而增加，孕36周胎动次数减少。胎动超日节律开始于孕28周。这项研究继续在压力条件下的孕妇。

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.
