Abstract

Magnetic responses of the brain to rhythmic visual stimulation are measured at frequencies of ~10 Hz using a 7-channel SQUID magnetoencephalograph. Despite the stationarity of the stimulation, the responses of the brain demonstrate the constant instability of the amplitude and spatial distribution of the magnetic field. The signal from the eyes is periodically redirected to different parts of the cortex, although the stimulation is always the same.

使用7通道SQUID磁控器检测对连续节律性视觉刺激的皮质脑反应的散射

摘要

使用7通道SQUID磁脑图仪在〜10 Hz的频率下测量大脑对节律性视觉刺激的磁响应。尽管刺激是平稳的，但大脑的反应表明磁场的振幅和空间分布始终处于不稳定状态。来自眼睛的信号会定期重定向到皮质的不同部分，尽管刺激始终是相同的。
