Abstract
A BCI apparatus () for supporting the rehabilitation of stroke patients () with motor impairments is provided, comprising a probe () for recording a neuronal activity signal, an evaluation unit () for analysis of the activity signal, and an effector () which is controlled by the evaluation unit () in dependence of a detected motion, wherein a session control unit () is configured to output a request to the patient () to generate a desired activity pattern, to at the same time record the activity using the probe (), and to give the patient () a feedback via the effector whenever the desired activity pattern is identified by the evaluation unit (). The request includes an instruction to imagine a specific movement or to try to execute the specific movement, wherein the probe () is an ECoG electrode with at least twenty individual electrodes (), and wherein the evaluation unit () is configured to provide a plurality of frequency channels for the identification of the desired activity pattern and to evaluate the activity signal based on at least one of the amplitude and the phase in the frequency channels.
