An apparatus (1) for the stimulation of neurons with a synchronized and pathological oscillatory neuronal activity, comprising: - a stimulation unit (11) with a plurality of stimulation contacts (25-28) for the stimulation of neurons in the brain and / or in the spinal cord of a patient with electrical stimuli (22), - a unit of measurement (12) for recording measurement signals (23), which reproduce a neuronal activity of stimulated neurons, and - a unit of control and analysis (10) for the control of the stimulation unit (11) 10 and for the analysis of the measurement signals (23), characterized in that the control and analysis unit (10) is configured in such a way so that - it activates the stimulation unit (11) in such a way that the stimulation contacts (25-28) apply stimuli (22), - with the help of the measurement signals (23) recorded as a reaction to the application of the stimuli (22), the s stimulation contacts (25-28), whose stimuli cause a restart of the phases of the synchronized neurological and pathological activity of the stimulated neurons, - the stimulation unit (11) is activated in such a way that the stimulation contacts ( 25-28) selected apply stimuli (22) for resetting the phases in a time-shifted manner, and - with the help of the measurement signals (23) recorded as a reaction to the stimuli (22) for restarting the applied phases in a time-displaced manner, it is verified whether the stimuli (22) of restarting the applied phases in a time-displaced way suppress the pathological synchronized and oscillatory neuronal activity of the stimulated neurons.Un aparato (1) para la estimulación de neuronas con una actividad neuronal sincronizada y oscilatoria patológica, que comprende: - una unidad de estimulación (11) con una pluralidad de contactos de estimulación (25-28) para la estimulación de neuronas en el cerebro y/o en la médula espinal de un paciente con estímulos eléctricos (22), - una unidad de medición (12) para el registro de señales de med
