Fig. 5|

(a) Schematic of monkey isometric wrist task. Force and dF/dt are shown for three consecutive successful trials. The target acquisition phases are indicated by arrows corresponding to the target directions. Black lines denote target onset. Grey intervals denote return to and hold within the central target. (b) Example AutoLFADS output (blue) overlaid on rectified EMG (black) for four forearm muscles that have a moment about the wrist (EDC: extensor digitorum communis, ECU: extensor carpi ulnaris, FCU: flexor carpi ulnaris, FDS: flexor digitorum superficialis). (c) Top three principal components of AutoLFADS output for four conditions, colored by target hold location (total variance explained: 88%).
