Abstract
The invention relates to a method and a device for desynchronizing neural brain activity, a controller and a method for treating neurological and/or psychiatric disorders. According to the invention, low-frequency successions of high-frequency pulse trains are applied in corresponding brain regions. This suppresses symptoms and even brings about a cure in some cases.

73. A device comprising:
-
at least one electrode and/or at least one chip for stimulating cerebral neurons which have a pathological oscillatory activity with a pathological frequency;
at least two contact points which are distributed over at least one electrode and/or over at least one chip, which output electrical stimulus signals to the brain; and
a controller, which drives the contact points in such a way that the contact points output low-frequency sequences of high-frequency pulse trains to the brain, the frequency of a low-frequency sequence of high-frequency pulse trains that is applied via an individual contact point essentially corresponding to the pathological frequency or an integral multiple thereof with an integral multiplication factor of less than 1000. - View Dependent Claims (75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 97)

94. A method for treating neurological and/or psychiatric disorders in which morbidly synchronous neural activity is present, comprising:
via at least two contact points which are distributed over at least one electrode and/or over at least one chip, applying electrical stimuli in the form of low-frequency high-frequency pulse trains to the morbidly synchronously firing neurons of the brain and/or to fiber paths connected to said neurons and/or to synchronously firing neurons connected thereto, the frequency of a low-frequency sequence of high-frequency pulse trains that is applied via an individual contact point essentially corresponding to the pathological frequency of the morbidly synchronous neural activity or an integral multiple thereof with an integral multiplication factor of less than 1000.
