Squid Instrumentation for Neuromagnetic Study of Complex Brain Activity,
Abstract
The impressive results obtained during the last few years by applying the neuromagnetic method to the investigation of brain physiology and pathology have given an extraordinary impulse to the development of large multi-sensor systems, which should permit, in a relatively near future, to simultaneously detect the distribution of the magnetic field over a large area of the scalp and to achieve a real time functional localization of active cerebral sources. in this paper an outline of the main instrumental problems in the choice of an optimal sensor configuration - for large multichannel systems - is presented, with particular emphasis on the capability featured by different kinds of superconducting gradiometers to identify complex cerebral sources, and on the need for more sophisticated model sources.
