The paper demonstrates that increased spinal reflex responses to loads reduce motor cortex activity, using a neural network model to show how lower-level feedback influences goal-directed motor corrections.

This study shows macaques can exploit goal redundancy in motor tasks, similar to humans, by adjusting their responses based on visual and proprioceptive feedback.

The paper shows that rotational dynamics in motor cortex can arise from sensory feedback, even without recurrent connections, and are also present in somatosensory cortex and feedback signals.

The paper examines how visual and proprioceptive feedback influences activity in primary motor cortex neurons, finding that ~73% of neurons respond to at least one feedback source and that limb and goal feedback converge on the same neurons.

This study shows that primary motor cortex maintains representations of both ipsilateral and contralateral limbs during bimanual movements, with greater stability in contralateral limb representations.

The paper shows that primary motor cortex neurons respond independently to contralateral and ipsilateral arm movements, with distinct response magnitudes and timing, and that these responses are segregated into orthogonal subspaces.
