Abstract: In the last half decade, fast methods of magnetic resonance
imaging have led to the possibility, for the first time, of noninvasive
dynamic brain imaging. This has led to an explosion of
work in the Neurosciences. From a signal processing viewpoint the
problems are those of nonlinear spatio-temporal system identification.
In this paper, we develop new methods of identification using
novel spatial regularization.We also develop a new model comparison
technique and use that to compare our method with existing
techniques on some experimental data.
