Neuromagnetic source location estimation in the cortical region using MR images

Abstract

The authors present neuromagnetic source location estimation in the cortical region using MR images. As there are many neurons on the cortex, the authors regard it as a prime candidate for source location. The cortex is extracted from MR images. The authors assume that the points on the extracted cortex are current dipoles and all the acquired points are considered as candidate sources. The authors then perform the estimation on the extracted cortex by means of the MUltiple SIgnal Classification (MUSIC) method. They apply this algorithm to real human brain data.
