Abstract: A method for analyzing synchronizations of the electroencephalography of an individual using a set of sensors starting from cerebral electromagnetic analysis of the individual. The method creates a database by acquisition and digitization of electrophysiological signals output from the sensors, and calculates the degree of synchronization existing between all pairs of sensors recorded in an assembly protocol, in frequency bands between 0 and 2000 Hz, to build up the database of classes each characterizing a reference state. The method further performs statistical validation of a period analyzed in real time, which assigns this period to a class in the database, and detects a specific period with a determined degree of synchronization. A device implements this method.

Abstract: The invention relates to a method of representing a dynamic functional image of the brain. It consists in acquiring (A) for a specific duration a plurality of electrophysiological signals {esi}1N of cerebral activity from a set of electrodes {Ei}1N placed on the scalp (S) of the subject, in locating (B) the set of neuroelectric generators {{right arrow over (g)}jk}11JK in the cerebral volume from a three-dimensional image {Ck}1K made up of successive cross-sections of the brain, and in applying the inverse problem, and within active zones that include neuroelectric generators discriminating (C) the amount of synchrony that exists between electrophysiological signal and neuroelectric generator pairs in a plurality of frequency bands, to detect groups of discriminating neural networks {RNdk}1K. The invention is useful for non-invasive study of provoked or unprovoked functional anomalies.

Abstract: A frame (1) with driving members (9-11) for translating and/or rotating an assembly (4) movably mounted in said frame along one of the three planes defining the space. A unit for mechanically controlling said driving members is arranged to enable the stationary patient on the movable assembly (4) to be exposed to a moving elementary stimulation having monotonic space-time characteristics with a speed- and/or acceleration-adjustable profile, by translation and/or rotation thereof along at least one of said three planes of the space. The device further includes a processing unit for digitising waves sensed by at least some of the electrodes of an electrophysiological helmet on the patient's skull, and for finding therein evoked potentials that match the profile of the elementary stimulation. Real-time data on the functioning of at least one part of the vestibular system may thus be obtained.
