Standard brain imaging methods portray neurological properties such as
perfusion (blood flow), sucrose uptake, or basic anatomical features.
These depictions are all secondary to the primary function of the brain
which is information processing and computation. The present invention
provides for an imaging method based directly on brain function. It
images the amounts and changes of information in the function of the
brain. This is accomplished my measuring brain information at small time
and spatial (anatomical) intervals. At each of these intervals, an
informational value is computed. The changes in these values are computed
by using known neurophysiological constraints, statistical optimization,
or a combination of these two methods. These changes can then be depicted
in tomographs, if the user so desires. The result is a clear description
of brain function at the primary level.
