Results of recursive feature selection for all eight observed degrees of freedom. Combining SUA and LFPstft signal types produced neural filters with greater predictive strength than each signal individually. In cases where another individual signal type was the most informative (e.g. LFPrms in shoulder flexion / extension), the combined signal decoders performed as well or better than the other signal type. Results are from one trial 966 days post-implant.
