Confirmation

This report shows that local field potentials (LFPs) recorded from monkey motor cortex contain information about the direction of arm movements made to reach targets. The direction of movement could be inferred on a single-trial basis if all LFP data recorded from multiple (48) electrodes was used. The 'decoding power' of LFPs used in this way was as good as decoded from single unit activity recorded on the same set of multiple electrodes. The result confirms an earlier study for oculomotor movements and indicates that LFPs could be used to guide brain-machine interfaces.
