摘要:
A device for decoupling and/or desynchronizing neural, pathologically synchronous brain activity, in which, the activities in a partial region of a brain area or a functionally associated brain area are stimulated by means of an electrode, resulting in decoupling and desynchronizing the affected neuron population from the pathological area and suppression of the symptoms in a patient. In an alternative embodiment of the device, the pathologically synchronous brain activity due to the disease is desynchronized which also leads to the symptoms being suppressed. The device has a stimulation electrode and at least one sensor which are driven by a control system in such a manner that they produce decoupling and/or desynchronization in their local environment.

The invention relates to a device for desynchronizing neuronal brain activity. According to the invention, the activity in at least two partial zones of a brain area or at least two functionally related brain areas is reset by means of two electrodes, surprisingly resulting in desynchronization in the targeted population of neurons of the patient and the symptoms being repressed. The inventive device comprises at least two stimulation electrodes (2) which are triggered by a control mechanism so as to cause synchronization in the local environment thereof. Preferably, the stimuli of the N electrodes are essentially out of phase by 1/N.

An apparatus (100) is described which comprises at least one measuring unit (31-34) for recording test signals from neurons, a generator unit (10) for generating electrical stimulation signals in accordance with the test signals, and a plurality of stimulation units (11-14) that are connected to the generator unit (10). The stimulation units (11-14) stimulate a plurality of neural networks in a deferred manner by means of the stimulation signals and thus induce a deferred activity in the stimulated neural networks.
摘要:
A device having a first stimulation unit that generates electrical first stimuli suppressing a pathological synchronous activity of neurons in the brain and/or spinal cord of a patient upon administering the same to the brain and/or spinal cord of the patient, a second stimulation unit that generates optical and/or acoustic and/or tactile and/or vibratory second stimuli, and a controller that controls the first and the second stimulation units. The generation of the first and second stimuli optionally occurs in a first or in a second operating mode, and the controller actuates the first and the second stimulation units such that in the first operating mode the generation of at least 60% of the second stimuli is chronologically coupled to the generation of the first stimuli, and in the second operating mode the generation of at least 60% of the second stimuli is carried out without generating the first stimuli.
