Composed dynamic topography for spike and sharp wave.
We reported two kinds of dynamic topographies. In one, an interspike interval histogram and a computerized topography of the EEG basic activity were composed. In the other, spike and sharp wave characteristics were composed of an isopotential topography. These topographies enabled us to observe serial changes in epileptic discharge dynamically by 1 msec.
