The paper examines how object identity is represented in sensorimotor cortex during the transition from hand opening to grasping, finding that neural representation shifts from motor and proprioceptive areas before contact to cutaneous and integrative somatosensory areas after contact.

The paper shows that neuronal population dynamics in motor cortex differ between reaching and grasping movements, suggesting different circuit mechanisms for each task.

The paper shows that hand movements outside a previously identified subspace are structured and task-dependent, indicating volitional control beyond the assumed subspace.

The paper investigates neural representations of hand postures during grasping in primates, finding that somatosensory and motor cortex track multi-joint hand configurations differently than arm movements during reaching.
