Abstract

A description is given of the theory and instrumentation involved in measuring magnetic fields of the brain. The magnetic counterpart of event-related potentials are capable of locating more accurately the generators of these electrical signals. Preliminary results of the first application of magnetoencephalography in Australia are presented. These localize the generator of the auditory P300 event-related potential component to the temporal cortex.

摘要

本文描述了测量脑磁场所涉及的理论和仪器设备。事件相关电位的磁对应物能够更精确地定位这些电信号的发生器。文中展示了澳大利亚首次应用脑磁图的初步结果。这些结果将听觉P300事件相关电位成分的发生器定位到颞叶皮质。
