Electroencephalograph having meter probe movable in a calvarium-shaped liquid filled tank and method of use

摘要: An electroencephalograph wherein movable electrodes are attached to positions on a scalp corresponding the of fixed an inverted, calvarium-shaped hollow member electrical insulating material, for example, methyl methacrylate. Differences between potentials in each amplified and passed electrode, so that by moving probe around saline solution indication distribution potential brain may be obtained.
