Method for modulation of neuronal activity in the brain by means of sensory stimulation and detection of brain activity
First Claim
1. A method for desynchronizing pathologically rhythmic brain activity, the method comprising:
- generating a periodic succession of a plurality of pulses to stimulate neuronal rhythmic activity in a patient'"'"'s brain, wherein a frequency at which the plurality of pulses are generated in the periodic succession is increased from a first limit to a second limit during the periodic succession;
measuring the neuronal rhythmic activity in response to the periodic succession of the plurality of pulses;
determining at least one frequency in which a maximum excitation of the neuronal rhythmic activity is measured in response to the periodic succession of the plurality of pulses;
generating an entraining periodic pulse sequence operating at the at least one frequency to entrain the phase dynamic of the neuronal rhythmic activity; and
generating a desynchronization pulse following the entraining periodic pulse sequence to desynchronize the neuronal rhythmic activity,wherein the plurality of pulses, the entraining pulse sequence and the desynchronization pulse are either visual or acoustic or tactile.

Abstract
The invention relates to a method for controlled modulation of physiological and pathological neuronal rhythmic activity in the brain by means of sensory stimulation, which is capable of diagnostically ascertaining functional disorders in the brain and of alleviating or eliminating the symptoms of a functional disruption. According to the invention, the method comprises generating a plurality of pulses at a plurality of excitation frequencies, respectively, to stimulate neuronal rhythmic activity in a patient'"'"'s brain; measuring the neuronal rhythmic activity in response to the pulses; determining an excitation frequency in which the measured neuronal rhythmic activity has a maximum amplitude of pathological rhythm; generating an entraining periodic pulse sequence operating at the excitation frequency; and generating a desynchronization pulse following the entraining periodic pulse sequence to desynchronize the neuronal rhythmic activity, where the pulse are either visual or acoustic or tactile.
