Experimental setups for B2 and B3 experiments.
(A) Monkeys were seated in separate rooms, each facing a computer monitor showing the virtual avatar arm (inset in C) from a 1st person perspective. (B) Shows the shared control task, (X,Y) position of the virtual arm was decoded during centre-out movements from the two monkeys’ brains with each given 50% control of the arm. Electrode array location shown on brains. (C) Shows the partitioned control task. X position of the arm was decoded from one monkey and Y position from the other during centre-out movements toward targets. (D) Shows the 3-monkey task. Each monkey observed and had 50% control over 2 of the 3 dimensions (X, Y, or Z). Together, the three monkeys must accurately perform a 3-D centre-out movement to achieve reward.
