Data are from one experimental session per monkey and show the numbers of well-tuned muscles used in the mean ΔPD calculation. For monkeys KD and SP, additional muscles that were not well tuned but included in the population decoder analysis are reported in parentheses. The following muscles were evaluated: flexor carpi radialis (FCR), flexor carpi ulnaris (FCU), flexor digitorum superficialis (FDS), flexor digitorum profundus (FDP), extensor carpi radialis (ECR), extensor carpi ulnaris (ECU), and extensor digitorum communis (EDC).
