Limb amputation and related changes in body feelings are associated with cortical functional reorganization that is reflected by increased interhemispheric asymmetry of body maps in the postcentral somatosensory cortex (PCS). As a pilot test to deter

Magnetic resonance imaging (MRI) was used to evaluate within-subject variability in global mean cortical thickness over test-retest intervals of minutes-weeks in five healthy adults. Within-subject measures of global mean thickness were consistent ov

Cortical contributions to brainstem plasticity in the somatosensory system are poorly understood. Tactile receptive fields (RFs) of brainstem dorsal column nuclei (DCN) neurons rapidly enlarge when peripheral inputs are disrupted by local anesthetic

Central processing of tactile inputs from the hand begins in the main cuneate nucleus and continues in the thalamus and area 3b cortex. Little is known about cuneate functional organization in primates or about how cuneate and area 3b organization ar

Cerebral cortical maps in adult primates reorganize within minutes-hours after peripheral injuries, but subcortical versus intracortical contributions to this rapid reorganization remain controversial. The present results show that injury of nerves t

The area 3b hand cortex of adult squirrel monkeys was mapped during the first minutes to hours after transecting the radial and median nerves to the hand. The objective was to evaluate initial cortical reactions to this injury and to determine whethe

The fidelity of median nerve regeneration and the consequent effects of regeneration errors on cortical organization were determined in combined anatomical and electrophysiological studies. In three adult macaque monkeys, the median nerve was cut, su

A previous study has shown that fetal forelimb removal in the rat results in an increase in the size of the hindlimb representation in primary somatosensory cortex and suggested that this anomalous cortical organization may have resulted from alterat

The ulnar and radial nerves to the hands of 12–31-d-old marmoset monkeys were transected and ligated, and the monkeys were subsequently reared for periods of 1.4–1.6 years with only median nerve innervation to the hand. Features of organization i

Human precentral and postcentral cortical areas interact to generate sensorimotor functions. Recent imaging work suggests that pre- and postcentral cortical thicknesses of an individual vary over time-scales of years and decades due to aging, disease
