1. A method for desynchronizing neuronal brain activity of a patient in which the brain activity involves a neuron population firing in a synchronized manner, the method comprising: measuring a pathological frequency g of the neuronal brain activity of the patient, where the pathological frequency g relates to a pathological disorder of the patient; calculating a stimuli frequency f based on the measured pathological frequency g, where the stimuli frequency f is calculated as being equal to the measured pathological frequency g×n/m, where n is 1, 2 or 3 and m is 1, 2 or 3; and controlling an electrode to generate stimuli in sequence with the stimuli succeeding each other at the stimuli frequency f, where the stimuli stimulate the neuron population of the patient.
