Claim 9
Independent Claim
86 words
A method for generating a processed neural signal that encodes a reach plan of a subject relative to an eye-centered reference frame of the subject, the steps comprising: a) acquiring a neural signal from the subject using a sensor; b) isolating the neural signal so acquired; c) determining whether the neural signal so acquired encodes the reach plan; and d) selecting the neural signal that encodes the reach plan relative to the eye-centered reference frame of the subject so as to generate the processed neural signal.
Claim 10
Independent Claim
86 words
A method for generating a processed neural signal that encodes a reach plan of a subject relative to an eye-centered reference frame of the subject, the steps comprising: a) acquiring a neural signal from the subject using a sensor; b) isolating the neural signal so acquired; c) determining whether the neural signal so acquired encodes the reach plan; and d) selecting the neural signal that encodes the reach plan relative to the eye-centered reference frame of the subject so as to generate the processed neural signal.
