The main purpose of measurements of the magnetic field produced by cerebral electrical activity is to locate this activity or to determine its distribution in the brain. In this paper, methods to locate or otherwise characterize source currents in the brain are briefly discussed. It is emphasized that the optimal source estimation method depends crucially on the availability of prior information and on the questions one wants to resolve with the measurements.
测量由脑电活动产生的磁场的主要目的是定位这种活动或确定其在大脑中的分布。本文简要讨论了定位大脑中源电流或以其他方式对其进行表征的方法。需要强调的是,最佳的源估计方法关键取决于先验信息的可用性以及人们希望通过测量解决的问题。
