Extended Data Fig. 10: Motor preparation signals before joystick offset.
Two example non-periodic neurons in the EC showing motor-related activity before joystick offset similar to ‘memory-trace’ cells in Qasim et al.23. Overall, the majority of neurons in both monkeys showed such motor-related response, 77% (477/614) in monkey A and 70% (607/864) in monkey M (two-sample t-test (p < .0001) between average activity in the two intervals indicated by the shaded grey regions). Within the non-periodic population, the proportion of neurons with motor-related response was 81% (368/452) in monkey A and 89% (432/481) in monkey M.
