The purpose of this work is to suggest an implement a means to increase the effectiveness of neurocomputer interface functioning by forming an additional brain—computer feedback channel for the immediate control of the work of this interface. In the classical control scheme, which uses the brain-computer interface, between the beginning of conscious generation of commands by user and the receiving of those commands from the neurocomputer interface by the managed device, the user does not now whichever command is considered by the combined system as the most probable for evaluating. Neither is it known whichever of them are selected for transmission to the effector device, and what the relationships between their probabilities are, etc. As a result, the commands selected for evaluation will be visible only when the interface or the effector program have already evaluated them. In this article are considered the benefits of using an additional feedback channel for the brain—computer interfaces. Thus it is demonstrated that the existing combined software-hardware systems impose significant restrictions on the control of the brain-computer interface by the user. A new combined solution is demonstrated, that is suitable for both synchronous and asynchronous brain-computer interfaces. Such programs form a new feedback channel, that informs a human about the command creations in the software part of the brain-computer interface. This approach allows one to change the functioning of various brain structures more efficiently, than with a classical brain-computer interface scheme.
