BCI apparatus for stroke rehabilitation

A BCI apparatus (10) configured to support rehabilitation of stroke patients with motor impairments, comprising:

• a probe (18) configured to record a neuronal activity signal,
• an evaluation unit (24) operably connected to the probe and configured to analyze the neuronal activity signal, and
• an effector (18, 22, 26, 28) operably connected to and controlled by the evaluation unit,
• wherein the effector is controlled by the evaluation unit in response to a detected motion-related activity pattern detected in the neuronal activity signal detected by the evaluation unit,
• wherein the effector is configured to provide feedback about a degree of success of control of a motion related activity pattern detected in the neuronal activity signal, and
• wherein the effector includes a stimulator for brain tissue, and
• wherein the evaluation unit is further configured to output a request to the patient;
• the request including instructions to imagine a specific movement or to try to execute the specific movement, and wherein the probe (18) is an ECoG electrode with at least twenty individual electrodes (30), and
• wherein the evaluation unit is configured to provide a plurality of frequency channels for identification of the desired activity pattern and to evaluate the activity signal based on at least one of an amplitude and a phase in the frequency channels.
