I sympathise with your problem! Unfortunately I think there's little
available guidance to suggest a "correct" way, because we don't know
what kinds of neuronal activity produce fMRI signal. Are you wanting to
map the electrical EEG domain to the fMRI domain? That sounds like an
interesting problem and I will have a dig around to see what I can turn
up. Maybe Dr Agmon or Dr Norman could suggest some resources. My first
thought is the Brain Dynamics group here in Sydney, Australia - they
have produced models of EEG power spectra based on simple anatomical
properties of bulk cortical tissue. I don't think they have applied it
to correlation with fMRI though - although the members do use fMRI in
experimental contexts.

Hope that helps - it's much easier to know how to advise when you say
what you're trying to achieve!
