Abstract
In an electroencephalographic (EEG) system and method the subject's brain waves are recorded using electrodes removably connected to the scalp. The spatial resolution may be improved, in one embodiment, by 'Deblurring', based on digital computer processing measurements of the positions of the electrodes; measurements of the subject's head size, shape, scalp thickness, skull thickness and brain shape; and estimates of the conductivity of the skull, scalp and cerebral spinal fluid.
