Neural activity related to hand strength and dexterity was effectively mapped using fMRI, revealing both activation and deactivation patterns.
Assessment during finger tapping and force-matching tasks showed distinct regional responses in the brain and spinal cord structures.
Simultaneous brain-spinal cord fMRI in 28 participants demonstrated graded sensory and motor activation shifts corresponding to task difficulty.
Findings emphasize the importance of brain-spinal cord connections, suggesting implications for understanding motor impairments in clinical conditions.
