Abstract:
1. An implantable device for acquisition and monitoring of brain bioelectric signals, said implantable device comprising: a) a plurality of active electrodes suitable to be placed in contact with a patient's brain and configured to detect brain bioelectric signals, said plurality of active electrodes being arranged on a grid connected to an electronic module of the implantable device, wherein the active electrodes are connected to a microprocessor of said electronic module through respective paths different from each other, are formed on said grid and are connected to analog input units arranged in the electronic module, wherein b) at least one digital-to-analog converter arranged within the microprocessor and configured to generate electrical pulses having predetermined waveform and voltage on one or more pairs of electrodes comprising active electrodes and/or passive electrodes, the microprocessor being configured to perform brain stimulation by activating only the electrodes located in a region of the brain wherein a focus of a brain disease has been identified by simultaneously reading the outputs of the analog-to-digital converters.
