Analysis of the neuromagnetic data on the frequency responsivity of the human brain: a progress report

The study of the responsivity of the human brain at different rates of sensory stimulation has provided several pieces of information on brain functionality. The new analysis technique used in this study permits us to investigate the dynamics of these responses and to obtain a larger amount of statistical data to allow for fine frequency discrimination. This allows us to suggest, for example, phase locked systems as models for synchronisable spontaneous activity. Absence of subject fatigue during the repetition of the stimulation paradigm, as well as the presence of a 'learning period' characterised by transient dynamics of the responses, are also discussed.
