Figure 5: Closed-loop brain control using simulated ECoG data. (a) Time-frequency plots of a single simulated ECoG signal averaged across all repetitions of an 8-target center-out cursor control task. Plots are aligned to target presentation at time 𝑡 = 0 (dashed white line). In all, a total of 32 channels of simulated directionally tuned ECoG signals were generated. (b) Real-time cursor trajectories controlled by simulated ECoG signals using the population vector algorithm.
