Abstract

Biomagnetic brain activity was studied in 17 full-term pregnant women with symptoms of pre-eclampsia using the biomagnetometer SQUID. The results show obvious differences both in the waveforms and in the spectra that obtained from statistical Fourier analysis by comparing them with the corresponding results from 87 pregnant women with normal full-term pregnancies. Specifically, in the pathological pregnancies the high magnetic field activity emitted from points of the mother's brain is distributed in the 2-7 Hz band frequency range whereas in normal pregnancies we found low magnetic field activity distributed over the 7 Hz band frequency.

摘要

使用超导量子干涉装置（SQUID）生物磁力计对17名有先兆子痫症状的足月孕妇的脑生物磁活动进行了研究。通过将统计傅里叶分析获得的波形和频谱与87名足月正常妊娠孕妇的相应结果进行比较，结果显示出明显差异。具体而言，在病理妊娠中，母亲大脑各点发出的高磁场活动分布在2-7赫兹频段范围内，而在正常妊娠中，我们发现低磁场活动分布在7赫兹频段以上。
