SYSTEM FOR RECORDING AND PROCESSING NEURAL ACTIVITY

摘要

A system for recording electroneurographic activity comprising at least three electrodes capable of sensing a nerve signal from a peripheral nerve and having means for receiving and processing the sensed nerve signal to identify a signal indicative of a specific action being a movement of a body part performed by the patient and for producing a control signal in response thereto featuring means for amplifying or attenuating signals in a specific direction of propagation without adversely affecting the electroneurographic activity being measured.

主权项

1. A system for recording neural activity, comprising:
at least three electrodes adapted to be arranged along a longitudinal axis of a peripheral nerve; at least one device to amplify and process nerve signals sensed by the at least three electrodes and to emphasize the neural signals in a neural propagation direction of interest; wherein a time delay which is inversely proportional to a conduction velocity of the neural signals is added to at least one bipolar channel which is first passed by the neural signals.
