Thirty-two college students (16 male, 16 female) had EEG recorded during computerized two- and three-dimensional mental rotation tasks. The simple two-dimensional mental rotation task was associated with more left parietal than right parietal activation in men and more right parietal than left parietal activation in women. The complex three-dimensional mental rotation task was associated with g...

Neuroimaging evidence suggests that the parietal lobe has an important role in memory retrieval, yet neuropsychology is largely silent on this topic. Recently, we reported that unilateral parietal lobe damage impairs various forms of visual working memory when tested by old/new recognition. Here, we investigate whether parietal lobe working memory deficits are linked to problems at retrieval. W...

The primate brain is adept at rapidly grouping items and events into functional classes, or categories, in order to recognize the significance of stimuli and guide behavior. Higher cognitive functions have traditionally been considered the domain of frontal areas. However, increasing evidence suggests that parietal cortex is also involved in categorical and associative processes. Previous work ...

Current views of the parietal cortex have difficulty accommodating the human inferior parietal lobe (IPL) within a simple dorsal versus ventral stream dichotomy. In humans, lesions of the right IPL often lead to syndromes such as hemispatial neglect that are seemingly in accord with the proposal that this region has a crucial role in spatial processing. However, recent imaging and lesion studie...

The order of events, whether two events are seen as simultaneous or successive, sets the stage for the moment-to-moment interpretation of the visual world. Evidence from patients who have lesions to the parietal lobes and transcranial magnetic stimulation studies in normal subjects suggest that the right inferior parietal lobe underlies this analysis of event timing. Judgment of temporal order,...

p0010 According to a long standing idea, reaching movements are supported by the dorsomedial parietofrontal circuit consisting of the superior parietal lobule (SPL) and the dorsal premotor cortex (PMd), whereas grasping movements entail the dorsolateral parietofrontal network involving the inferior parietal lobule (IPL) and the ventral premotor cortex (PMv). Recently, however, this dichotomist ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2016-215812 DESCRIPTION A midline posterior parietal cystic structure— 2×2 cm—was diagnosed in a routine 22-week ultrasonographic scan. It did not appear to have communication through parietal bone or with sutures of the brain compartment. In the 24th week, an MRI was p...

There is increasing evidence from functional magnetic resonance imaging (fMRI) that visual awareness is not only associated with activity in ventral visual cortex but also with activity in the parietal cortex. However, due to the correlational nature of neuroimaging, it remains unclear whether this parietal activity plays a causal role in awareness. In the experiment presented here we disrupted...

An intriguing puzzle in cognitive neuroscience over recent years has been the common observation of parietal lobe activation in functional neuroimaging studies during the performance of human memory tasks. These findings have surprised scientists and clinicians because they challenge decades of established thinking that the parietal lobe does not support memory function. However, direct empiric...
