There are several kinds of non-invasive imaging methods that are used
to collect data from the brain, e.g., EEG, MEG, PET, SPECT, fMRI, etc.
It is difficult to get resolution of information processing using any one
of these methods.  Approaches to integrate data sources may help to get
better resolution of data and better correlations to behavioral phenomena
ranging from attention to diagnoses of disease.  The approach taken here
is to use algorithms developed for the author's Trading in Risk Dimensions
(TRD) code using modern methods of copula portfolio risk management,
with  joint probability distributions derived from the author's model of
statistical mechanics of neocortical interactions (SMNI).  The author's
Adaptive Simulated Annealing (ASA) code is for optimizations of training
sets, as well as for importance-sampling.  Marginal distributions will
be evolved to determine their expected duration and stability using
algorithms developed by the author, i.e., PATHTREE and PATHINT codes.
