摘要：
Electroencephalogram (EEG) dynamics results from the motion of charged particles in the brain. By invoking the laws of classical physics, we show that EEG dynamics obeys, at short enough times, a piece-wise quadratic Langevin equation characterized by an effective mass matrix, a piece-wise quadratic potential energy surface, a friction and random force matrix. In analyzing a sample seizure, we find with seizure onset a marked increase in the frequency of encounters with inflection points on the potential energy surface. (c) 2004 Elsevier B.V.
