Simulations show that the Maximum Entropy Method is a promising technique for image reconstruction in magnetoencephalography. An algorithm based on the work of Skilling and Bryan and an appropriately modified expression for the `entropy` is shown to provide high-quality reconstructions of both isolated and dense distributions of neural current `dipoles,` neglecting return currents. In particular the results are substantially superior to those obtained with the well-known Minimum Norm procedure. 12 refs., 6 figs.
