摘要: After the first neuromagnetic measurements with single-SQUID instruments in early 1970’s, multi-channel devices were built several laboratories (for a review, see Ilmonierni et al., 1989). However, number of channels has been rather limited and multiple at different dewar positions are generally needed for locating neural current sources accurately. We just getting ready complete multichannel system studies. It consists 24-channel dc-SQUID gradiometer, signal detection electronics, preconditioning measurement control data acquisition system, probe position indicator (PPI), computer hardware, software analysis data. This paper will give an overview our then concentrate on features which have main responsibility author.
