Abstract
Prosthetic devices, methods and systems are disclosed. Eye position and/or neural activity of a primate are recorded and combined. The combination signal is compared with a predetermined signal. The result of the comparison step is used to actuate the prosthetic device.
Claims28
A method to control spatial positioning of a prosthetic device, the prosthetic device able to assume multiple spatial positions upon input from a subject, the method comprising:
- recording an eye position of the subject to produce an eye position signal;
- recording a neural activity of the subject to produce a neural activity signal;
- combining the eye position signal and the neural activity signal to provide a recorded behavioral pattern;
- comparing the recorded behavioral pattern with at least one predetermined behavioral pattern to identify a matching predetermined behavioral pattern, the at least one predetermined behavioral pattern associated with at least one predetermined spatial position of the prosthetic device;
- and
- positioning the prosthetic device in the spatial position associated with the matching predetermined behavioral pattern.
A method to control spatial positioning of a prosthetic device, the prosthetic device able to assume multiple spatial positions upon input from a subject, the method comprising:
- recording an eye position of the subject to produce an eye position signal;
- comparing the eye position signal with at least one predetermined eye position signal to identify a matching predetermined eye position signal, the at least one predetermined eye position signal associated with at least one predetermined spatial position of the prosthetic device;
- and
- positioning the prosthetic device in the spatial position associated with the matching predetermined eye position signal.
A prosthetic device able to assume a spatial position on input of a subject, the prosthetic device comprising:
- means for recording an eye position of the subject to produce an eye position signal;
- means for recording a neural activity of the subject to produce a neural activity signal;

- means for storing at least one predetermined behavioral pattern, the at least one predetermined behavioral pattern associated with at least one spatial positioning of the prosthetic device;
- means for comparing the recorded behavioral pattern and the at least one predetermined behavioral pattern to identify a matching predetermined behavioral pattern;
- and
- means for positioning the prosthetic device in a spatial position associated with the matching predetermined behavioral pattern.
A prosthetic device able to assume a spatial position on input of a subject, the prosthetic device comprising:
- an eye position recorder to produce an eye position signal;
- a neural activity recorder to produce a neural activity signal;
- a component to combine the eye position signal and the neural activity signal to produce a recorded behavioral pattern;
- a storage mechanism to store at least one predetermined behavioral pattern, the at least one predetermined behavioral pattern associated with at least one spatial positioning of the prosthetic device;
- a processor to compare the recorded behavioral pattern and the at least one predetermined behavioral pattern to identify a matching predetermined behavioral pattern;
- and
- a control system to position the prosthetic device in a spatial position associated with the matching predetermined behavioral pattern.

- and
- a control system to position the prosthetic device in a spatial position associated with the matching predetermined eye position signal.
A method to investigate neural basis of a natural behavior in subjects, the method comprising:
- providing at least one subject;
- providing a behavioral task, the behavioral task simulating the natural behavior in subjects;
- recording the behavior of the at least one subject during the behavioral task;
- recording the eye movement of the at least one subject during the behavioral task;
- recording the neural activity of the at least one subject during the behavioral task;
- and
- combining the recorded behavior, the recorded eye movement and the recorded neural activity to identify a pattern of recorded eye movement and neural activity characterizing the natural behavior.
