Patent ID: 8694087

Claim:
A Brain Computer Interface (BCI) system comprising: one or more sensors configured to detect neuronal activity of one or more cortical or subcortical neuronal populations involved in arousal regulation of a selected patient's brain; a state monitoring module coupled to the one or more sensors, configured to store and process a first set of variables associated with a state of the detected neuronal activity; a performance monitoring module coupled to the one or more sensors, configured to store and process a second set of variables associated with an information rate of the detected neuronal activity, and configured to output the information to an output device via a communication channel; and a processing module coupled to the state monitoring module and the performance monitoring module, configured to extract a feature vector based upon the processed first and second set of variables, and configured to stimulate, in response to the detected neuronal activity, a region of the patient's brain involved in arousal regulation under conditions effective to adjust the output of information through the communication channel.
