Abstract: An intra-calvarial implant (ICI) includes one or more electrodes for sensing electrical signals from a brain of a mammal and for electrically stimulating one or more regions of the brain. The electrode(s) are implanted between an outer table and an inner table of the calvarial bone without fully penetrating the inner table, at least one reference electrode, an electronic circuitry module operatively connected to the one or more electrode(s) and to the reference electrode and for controlling the sensing and the stimulating, for at least partially processing the sensed electrical signals to obtain data for storing the data and for wirelessly transmitting the data to an external receiver. The ICI also includes a power harvesting device suitably electrically connected to one or more components of the electronic circuitry module of the ICI for energizing one or more components of the ICI. An ICI system includes ICI(s) and an external controller.

Abstract: A brain computer interface (BCI) system for modulating cognitive performance. The system includes one or more electrode sets for sensing signals associated with neuronal electrical activity in one or more cortical regions of the user and for providing stimulating signals to one or more target brain regions, at least one processor/controller in communication with the one or more electrode sets, and at least one power source. The processor/controller is programmed to process signals sensed in the one or more cortical regions for detecting an indication associated with an intention to perform a cognitive task and/or the presentation of a cognitive task and/or the performing of a cognitive task, and to control the stimulating of the one or more target brain regions responsive to the detecting of the indication for modulating the cognitive performance of the user. The target brain regions may include cortical regions, deep brain structures, and combinations thereof.
