The Dipole Theoretically, the current flows in a 3-3 dimensional ellipse with the greatest current density along a straight line connecting the positive pole to the negative pole The complex arrangement <strong>of</strong> the brain and head, differences in cell type and function within a region, and physical differences between brain areas result in an approximate dipole that is not a perfect model.
Rhythmical vs. Arrhythmical EEG Activity When EEG waves are rhythmical, most <strong>of</strong> the cells within the given neuronal pool are behaving similarly With arrhythmic activity, there is less correlation with individual cell behavior
