    Abstract

    Theory of frequency modulation of electroencephalogram (EEG) in human brain with/without photo-stimulation is presented. Firstly, physical/physiological significance of frequency modulation is discussed based on EEG data in the state of closed eyes at rest. Secondly, possible phenomenological theoretical models under photo-stimulation (PS) are examined to explain the features of intrinsic/induced frequency modulation and the frequency responses induced by PS. Properties of a generalized Kubo oscillator with a parametric periodic driving force are demonstrated to give the qualitative understandings of the observed age-dependent and light-induced natures of EEGs.
