Abstract

Magneto-encephalography is a promising technique for the in vivo monitoring of brain activity. The information about neural activity is reconstructed from the electrical current map of the brain, which is in turn deduced, via an inverse problem resolution, from the magnetic field map measured by superconductive quantum interference devices placed around the head. In this paper, a possible strategy to improve the detection ability of the procedure by optimally designing the representation system is proposed and discussed
