NONLINEAR OSCILLATION AND NEUROELECTRIC PHENOMENA. PART I
Abstract
Normal and epileptic electroencephalographic phenomena are treated from a new point of view. Phenomena such as (1) spontaneity of normal discharges, (2) epileptic involvement of normal neurons, (3) epileptic hypersynchrony, (4) ''exhaustion,'' and (5) normal and epileptic excitation and suppression effects are compared to phenomena of nonlinear oscillations such as (a) ''soft'' limit cycle behavior, (b) ''hard'' limit cycle behavior, (c) nonlinear entrainment effects, (d) oscillation hysteresis and Van der Pol oscillations, and (e) asynchronous excita tion and quenching effects, respectively. This paper treats (1), (2), and (a), (b), leaving the remainder to future communications. The goal of this work is to lead toward a mathemati cal phenomenological scheme which shows rela tionships between seemingly diverse neuroelec tric activity and to suggest new experiments which will increase out understanding of the brain mechanisms responsible for normal and ab normal activity.
