Selective right parietal lobe activation during mental rotation: a parametric PET study.
Regional cerebral blood flow (rCBF) was measured with PET in seven healthy subjects while they carried out a mental rotation task in which they decided whether alphanumeric characters presented in different orientations were in their canonical form or mirror-reversed. Consistent with previous findings, subjects took proportionally longer to respond as characters were rotated further from the up...
متن کاملParietal lobe contribution to mental rotation demonstrated with rTMS.
A large number of imaging studies have identified a role for the posterior parietal lobe, in particular Brodmann's area 7 and the intraparietal sulcus (IPS), in mental rotation. Here we investigated whether neural activity in the posterior parietal lobe is essential for successful mental rotation performance by observing the effects of interrupting this activity during the execution of a mental...
متن کاملDevelopmental aspects of parietal hemispheric asymmetry during mental rotation.
Response times, accuracy and event-related potentials were measured in 24 children (mean age 7.6 years), 24 juveniles (11.4 years) and 24 adults (23.8 years) during a mental rotation task with letters. Response time and error rates increased with angular displacements for all age groups. Increasing accuracy with increasing age suggested that this task was more difficult for younger participants...
متن کاملChildren’s left parietal brain activation during mental rotation is reliable as well as specific
Some recent evidence suggests that mental rotation of characters in children aged 7 or 8 years might be lateralized to the left parietal hemisphere. An alternative statement exists, however, the finding might be completely unspecific for mental rotation but either be simply a function of task difficulty or a consequence of the use of characters as stimuli. To test these alternatives, ERPs of 24...
متن کاملXenomelia: a new right parietal lobe syndrome.
BACKGROUND Damage to the right parietal lobe has long been associated with various disorders of body image. The authors have recently suggested that an unusual behavioural condition in which otherwise rational individuals desire the amputation of a healthy limb might also arise from right parietal dysfunction. METHODS Four subjects who desired the amputation of healthy legs (two right, one le...
