Inference of hand movements from local field potentials in monkey motor cortex

Nat Neurosci. 2003 Dec;6(12):1253-4. doi: 10.1038/nn1158. Epub 2003 Nov 21.


The spiking of neuronal populations in motor cortex provides accurate information about movement parameters. Here we show that hand movement target and velocity can be inferred from multiple local field potentials (LFPs) in single trials approximately as efficiently as from multiple single-unit activity (SUA) recorded from the same electrodes. Our results indicate that LFPs can be used as an additional signal for decoding brain activity, particularly for new neuroprosthetic applications.
