Topic: manual interception task

How does the motor cortex function in predictive sensorimotor control? This is important for understanding neural control of movement, but dauting for the tangling of high-dimensional sensory and motor information. To address this question, we recorded neural population activity from the motor cortex while the monkeys were performing a manual interception task. Interestingly, on the neural states of single trials, we observed a low-dimensional ring-like neural geometry. This geometry, featured with ordered reach-direction clusters and tilted target-speed rings, also emerges in a three-layer RN
