Abstract: PURPOSE: To determine the position of a source of electrical activity in a brain by forming a spatial filter for eliminating the other position although passing a nerval activity as to a specified position. CONSTITUTION: A signal from a plurality of electrodes 11 arranged in the already-known position of the head 12 is treated in digitization by CPU 17-19 including a row of the spatial filter.

Using these filter's output and estimating a signal electricity or dipole efficiency of each of the position in the brain, displaying the information onto a display device 21, and forming a map of an activity source in the brain.  These spatial filters don't need to know the number of the source in advance, but can identify the number of each of the source together with their position, electricity and the dipole efficiency. This information is used when a stimulation is given, orientating the nerval activity in the brain and identifying a diseased position in the brain.
