Figure 7. Decoding results for each individual electrode and performance of the two electrode selection methods.

A) Prediction performance for each electrode using all frequency bands. The color map in each electrode represents performance of that electrode. R² values ranged from 0.00 to 0.24 for monkey A and 0.00 to 0.63 for monkey B. B) Prediction performance of each electrode using the δ band. For monkey A, R² ranged from 0.00 to 0.24. For monkey B, R² ranged from 0.00 to 0.63. C) Prediction performance of each electrode using the γ3 band. For monkey A, R² ranged from 0.00 to 0.24. For monkey B, R² ranged from 0.00 to 0.63. D) Prediction performance of each electrode using the γ4 band. For monkey A, R² ranged from 0.00 to 0.24. For monkey B, R² ranged from 0.00 to 0.63. E) The blue solid and blue dotted lines represent the decoding performance for monkey A using the performance-based method and location-based method, respectively. The red solid and red dotted lines represent the decoding performance for monkey B using the performance-based method and location-based method, respectively. The solid stars and circles denote the highest performances for the performance-based method and location-based method, respectively.
