Dissociation in prefrontal cortex of affective and attentional shifts
Article Abstract:
Trained Marmoset monkeys were used in a study on the role of the prefrontal complex in disinhibition or loss of inhibitory control. Findings showed that injury to the lateral prefrontal complex deteriorated attentional set-shifting ability. On the other hand, damage to the orbitofrontal cortex produced futile attempts in preventing previously gained stimulus-reward associations. In short, inhibitory control in 'affective processing' was lost. It was then suggested that specific areas of the prefrontal complex had cognitive functions which were independent yet complementary.

Intellectual ability and cortical development in children and adolescents
Article Abstract:
A study was carried out to demonstrate that the trajectory of change in the thickness of the cerebral cortex, rather than cortical thickness itself, is most closely related to level of intelligence. The findings indicate that more intelligent children demonstrate a particularly plastic cortex, with an initial accelerated and prolonged phase of cortical increase, which yields to equally vigorous cortical thinning by early adolescence.

Phantom-limb pain as a perceptual correlate of cortical reorganization following arm amputation
Article Abstract:
The phantom-limb pain felt after arm amputation is because of the changes in the primary somatosensory cortex. The amount of cortical reorganization developed after upper-extremity amputation directly influences the phantom pain. There is a shift of the cortical map which is the most likely neurophysiological basis of the pain.
