The invention relates to a housing for a medical implant. The housing comprises a housing wall made of an electrically insulating material with an inner face and an outer face and an electrical transmission through the housing wall. The electrical transmission comprises an electrically conductive first terminal contact surface which is arranged on the inner face of the housing wall, an electrically conductive second terminal contact surface which is arranged on the outer face of the housing wall, a capacitor which is integrated into the housing wall and which comprises a first capacitor electrode and a second capacitor electrode, a first connection line which electrically connects the first terminal contact surface to the first capacitor electrode, and a second connection line which electrically connects the second terminal contact surface to the second capacitor electrode. No continuously electrically conductive connection exists between the first terminal contact surface and the second terminal contact surface.

The invention relates to a device for desynchronising neuronal, morbidly synchronous cerebral activity. According to the invention, the activity in at least two sub-sections of a cerebral area or at least two functionally allied cerebral areas is stimulated with the aid of at least two electrodes, which surprisingly causes a desyncronisation in the affected neurone population of an afflicted person, thus suppressing the symptoms. The stimulation feedback signal, i.e. the measured, time-delayed and processed neuronal activity is used as the individual stimulus. The invention thus permits a self-regulating demand control of the amplitude of the stimulation signal, whereby the intensity of the stimulation pulses are automatically minimised after successful desynchronisation. To operate successfully, the device requires neither complex calibration nor regulation of the stimulation parameters, the latter however can be advantageously adapted and optimised by the additional controller. Said device comprises at least two stimulating electrodes (2) and at least one sensor (3), which are controlled by a controller in such a way that they cause localised desynchronisation.

The invention relates to 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, surprisingly resulting in decoupling and desynchronization of the targeted neuron population from the patient's pathological area while the symptoms are suppressed. In an alternative embodiment of the inventive device, the pathologically synchronous brain activity is desynchronized, which also results in the symptoms being suppressed. The feedback stimulation signal, i.e. the measured, delayed, and processed neural activity, is used as a stimulus, whereby the stimulation signal is controlled on demand in a self-regulating manner such that the magnitude of the resulting stimulating influence on the neural population that is to be decoupled or desynchronized is automatically minimized once decoupling and/or desynchronization has been successful. The inventive device does not need to be calibrated with great effort nor do the stimulation parameters need to be regulated in order for the device to be operated successfully; however, said stimulation parameters can preferably be adjusted and optimized with the aid of an additional controller. The disclosed device comprises a stimulation electrode (2) and at least one sensor (3) which are triggered using a controller so as to cause decoupling and/or desynchronization in the local environment thereof.

The invention relates to a device for determining the frequency of at least one dominant tone of a tinnitus perceived by a patient, comprising a tone generator for playing tones, an input unit for patient entry of evaluations about the tones played, and a control and analysis unit coupled to the tone generator and the input unit and designed to carry out a similarity measurement and a comparison of pairs of tones, wherein the control and analysis unit controls the tone generator for the similarity measurement in such a way that same plays successive tones, and, after playing a respective tone, the control and analysis unit receives the patient's evaluation entered into the input unit with respect to the similarity of the tone to the at least one dominant tone of the tinnitus. The control and analysis unit controls the tone generator for the comparison of pairs of tones in such a way that it plays successive pairs of tones, and, after playing a respective pair, the control and analysis unit receives the patient's evaluation entered into the input unit as to which tone of the pair is more similar to the at least one dominant tone of the tinnitus, and the control and analysis unit combines the results of the similarity measurement and the comparison of pairs of tones and determines from this at least one tone, the frequency of which is most similar to the frequency of the at least one dominant tone of the tinnitus.

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.
