A new method of the description of the information flow in
the brain structures.
M.J.Kaminski and K.J. Blinowska
It _is_ as neat as it sounds! They've analyzed EEG signals in humans
and implanted electrodes in rats to determine the direction of information
flow. Their method uses spectral representations of time sereies data
from the electrodes. They've worked up a formula to calculate "directed
coherences" between channels. Also, they use partial coherences to
determine the magnitude of correlation. Could this approach be used to
noninvasively extract information from the brain to drive cybernetic
devices?
