Parameter identification for subject 2. Same convention as Figure 2. (A) Topographic map of determination coefficients between left hand versus right hand movements at the frequency used to identify sensors related to the SMR. These sensors were used during behavior identification and during feedback testing. (B) Plot of the largest regression values for subject 2 during behavior identification, indicating the frequencies at which the difference in coherence between the behaviors of interest was largest. Left index finger tapping versus rest elicited the largest determination coefficient (determination coefficients for other behavior pairs not shown). The frequency with largest determination coefficients was used in feedback testing for this subject, and the identified behaviors were used to control coherence.
