Increasing the information transfer rate of brain-computer interfaces

An apparatus for extracting one or more representations of salient features underlying the activities or states of neurons or similar entities or simulation of same.

An apparatus adapted to perform hierarchical decomposition of the feature space of features extracted from one or more representations of the activities or states of neurons or similar entities or simulation of same to provide a means of identifying and adaptively modifying/classifying simpler features (that are more likely to have characteristics common to most subjects) in parallel which are then re-combined to generate a signal or set of signals thus obviating or at least mitigating the need for extensive subject training.

A method of extracting information from neurons or similar entities or simulation of same, said method using input from one or more sensor elements or simulations thereof responsive to signals from said neurons or similar entities or simulation of same and transforming said signals into one or more representative formats.
