Experimental determination of compound action potential direction and propagation velocity from multi-electrode nerve cuffs.
MED ENG PHYS
531 - 534.
Information extracted from whole-nerve electroneurograms, recorded using electrode cuffs, can provide signals to neuroprostheses. However, the amount of information that can be extracted from a single tripole is limited. This communication demonstrates how previously unavailable information about the direction of action potential propagation and velocity can be obtained using a multi-electrode cuff and that the arrangement acts as a velocity-selective filter. Results from in vitro experiments on frog nerves are presented. (C) 2004 Published by Elsevier Ltd on behalf of IPEM.
