Summary To generate movements, the brain must combine information about movement goal and body posture. Motor cortex (M1) is a key node for convergence of these streams. How are posture organized within M1’s activity to permit flexible generation commands? answer this question, we recorded M1 while monkeys performed variety tasks with forearm in range postures. We found that posture- goal-related components neural population were separable resided nearly orthogonal subspaces. The subspace...
Abstract Internal states such as arousal, attention, and motivation are known to modulate brain-wide neural activity, but how these processes interact with learning is not well understood. During learning, the brain must modify activity it produces improve behavioral performance. How do internal affect evolution of this process? Using a brain-computer interface (BCI) paradigm in non-human primates, we identified large fluctuations population motor cortex (M1) indicative arousal-like state...
