Abstract

The effect of a constant uniform magnetic field of 0.1 to 1.6 T on the somatosensory potentials of the brain cortex and hypothalamus was investigated on nembutal anesthesized rats. The exposure increased the amplitude and modified the form of evoked potentials in both brain structures. The effect grew significantly with induction of the magnetic field. At every induction level changes in the evoked potentials of the hypothalamus were more distinct than those of the cortex. These findings were compared with the effects of a weakly pulsating magnetic field of the induction 0.1-0.4 T.

摘要

在戊巴比妥麻醉的大鼠身上,研究了0.1至1.6特斯拉恒定均匀磁场对大脑皮层和下丘脑体感电位的影响。暴露增加了两种脑结构中诱发电位的幅度并改变了其波形。随着磁场的感应,这种影响显著增强。在每个感应水平,下丘脑诱发电位的变化比皮层的更明显。将这些发现与感应强度为0.1 - 0.4特斯拉的弱脉动磁场的影响进行了比较。
