Phantom-limb pain as a perceptual correlate of cortical reorganization following arm amputation
A very strong direct relationship is reported between the amount of cortical reorganization and the magnitude of phantom limb pain (but not non-painful phantom phenomena) experienced after arm amputation, indicating that phantom-limb pain is related to, and may be a consequence of, plastic changes in primary somatosensory cortex.

Increased auditory cortical representation in musicians
The results, when interpreted with evidence for modified somatosensory representations of the fingering digits in skilled violinists, suggest that use-dependent functional reorganization extends across the sensory cortices to reflect the pattern of sensory input processed by the subject during development of musical skill.

Increased Cortical Representation of the Fingers of the Left Hand in String Players
The results suggest that the representation of different parts of the body in the primary somatosensory cortex of humans depends on use and changes to conform to the current needs and experiences of the individual. Expand
Modulation of early sensory processing in human auditory cortex during auditory selective attention.
It is demonstrated that focused auditory attention in humans can selectively modulate sensory processing in auditory cortex beginning as early as 20 msec poststimulus, thereby providing strong evidence for an "early selection" mechanism of auditory attention that can regulate auditory input at or before the initial stages of cortical analysis.

Effect of bilingualism on cognitive control in the Simon task: evidence from MEG
The present study used magneto-encephalography (MEG) to determine the neural correlates of the bilingual advantage previously reported for behavioral measures in conflict tasks, and found that the management of two language systems led to systematic changes in frontal executive functions. Expand
A high-precision magnetoencephalographic study of human auditory steady-state responses to amplitude-modulated tones.
The cerebral magnetic field of the auditory steady-state response (SSR) to sinusoidal amplitude-modulated (SAM) tones was recorded in healthy humans. The waveforms of underlying cortical sourceExpand
Human auditory evoked gamma-band magnetic fields.
We have discovered a ca. 40-Hz transient magnetic oscillatory response, evoked in the human brain by the onset of auditory stimuli, consisting of four or more cycles locked in phase to stimulus onsetExpand
Cortical reorganization and phantom phenomena in congenital and traumatic upper-extremity amputees
Sensory discrimination was normal and mislocalization (referral of stimulation-induced sensation to a phantom limb) was absent in the congenital amputees and the role of peripheral and central factors in the understanding of phantom limb pain and phantom limb phenomena is discussed. Expand
Tonotopic organization of the sources of human auditory steady-state responses
The findings suggest that the 40 Hz SSF may not consist of summated or entrained middle latency responses, as has previously been proposed, and alternative mechanisms for the SSR are discussed. Expand
Stimulus induced desynchronization of human auditory 40-Hz steady-state responses.
The time courses of ASSR amplitude and phase during recovery from the decrement resembled those after stimulus onset, indicating that a new ASSR was built up after the resetting stimulus, and the results are discussed as reset of oscillations in human thalamocortical networks. Expand
