The loss of a limb or paralysis resulting from spinal cord injury has devastating
consequences on quality of life. One approach to restoring lost sensory and motor abilities in …

Since the 1870s, the primary motor cortex (M1) has been known to have a somatotopic
organization, with different regions of cortex participating in control of face, arm, and leg …

The hand is one of the most fascinating and sophisticated biological motor systems. The
complex biomechanical and neural architecture of the hand poses challenging questions for …

Picking up an object requires two basic motor operations: reaching and gras**.
Neurophysiological studies in monkeys have suggested that the visuomotor transformations …

Small-object manipulation is essential in numerous human activities, although its neural
bases are still essentially unknown. Recent functional imaging studies have shown that …

A review of the research on anatomical and functional asymmetries in human primary motor
cortex suggests that the area of hand representation is greater in the dominant than in the …

The purpose of this study was to quantify the long-term loss of independent finger

The primary motor (M1) and somatosensory (S1) cortices play critical roles in motor control
but the signaling between these structures is poorly understood. To fill this gap, we recorded …

Only after injury, or perhaps prolonged exposure to cold that is sufficient to numb the fingers,
do we suddenly appreciate the complex neural mechanisms that underlie our effortless …
