Cortical Processing of Visual Parts and Wholes
… processes correspond to activation in the parietal lobe, particularly the intraparietal sulcus (IPS). This study combined theories of visual part structure with neuroimaging methods to investigate the relative contribution of holistic and configural processing in an ecologically valid …

Behavioral and Functional Brain Correlates of Developmental Coordination Disorder: A Case-Control Study
… 0.01) in the left motor cortex and left inferior parietal lobe while performing the tracking task. These results imply that the DCD subject relied heavily on visual (instead of tactile) feedback when performing the visuo-motor task as opposed to the control subject who exhibited significant …

Blushing and gaze avoidance in social anxiety disorder : a structural neuroanatomical investigation
… a (p<0.01), while the volumes of left inferior parietal lobe b (p=0.04) and left occipital cortex a (p<0.01) were decreased. With increased gaze fear and avoidance, there were associated decreases in the right posterior cingulate cortex a (p<0.01), right occipital lobe b (p=0.03) and right …

Functional MRI Activation of Inhibitory Control in Adolescents and Young Adults with Multiple Sclerosis
… parahippocampal gyrus, precuneus, superior parietal lobe, precentral gyrus and superior frontal gyrus. Cognitively intact pediatric-onset MS patients show less brain activation than controls when inhibiting a simple motor response despite no differences in behavioural performance. Functional …

A Comparison of the Frontal Variant of Alzheimer's Disease with Typical Alzheimer's Disease and Frontotemporal Dementia
… in the literature in which prominent frontal lobe dysfunction accompanies typical temporal and parietal lobe dysfunction in the early stages of the illness. However, no study has investigated how executive deficits and neuropsychiatric symptoms of the FvAD subgroup differ from those seen in …

Cerebral damage associated with alcoholism
… principally deteriorated on the tests of frontal lobe functioning, followed by lesser impairment on the tests of temporal lobe functioning, with no evidence of impairment on the tests of parietal lobe functioning~ No significant group differences were found betv1een the early stage alcoholics and …

Parietal dysfunction in children with prenatal alcohol exposure
The parietal lobe has been shown to be one of the regions most affected by prenatal alcohol exposure. Functional domains dependent on intact parietal functioning, including mathematical and visuospatial ability, have been consistently implicated in fetal alcohol spectrum disorders. This thesis …

Salience and Frontoparietal Network Patterns in Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
… disorders: the salience network (SN) and frontoparietal network (FPN). The SN is a network anchored by bilateral anterior insula and the dorsal anterior cingulate cortex and has been implicated in “bottom-up” attentional processes for both internal and external events. The FPN is anchored by …

Abnormal cell patterning at the cortical gray-white matter boundary in autism spectrum disorders
… temporal gyrus (BA 21), dorsolateral frontal lobe (BA 9), and dorsal parietal lobe (BA 7) of each case. A sigmoid curve was fitted to the transition zone between layer VI and underlying white matter (subplate), and the slope of the resulting curve was used as a measure of the spatial extent of …

THE EFFECTIVENESS OF BUPROPION SR ON DEPRESSIVE SYMPTOMS IN SMOKERS: SELF-REPORTS, EEG, AND INDIVIDUAL DIFFERENCES
… symptoms (e.g., Glassman et al., 1998). Here the parietal EEG alpha asymmetry was used as a dimensional neuropsychological marker of depressive symptoms (i.e., the more depressed, the higher alpha power in the right vs. left parietal lobe during visuospatial tasks [Henriques & Davidson, 1997; Rabe …

A Short Window Granger Causality Approach to Identify Brain Functional Pattern Associated with Changes of Performance Induced by Sleep Deprivation
… in two directions, from medial frontal lobe to sub cortical gray nuclei and from medial parietal lobe to sub cortical gray nuclei, were associated with shorter response time in the SD condition. Additionally, an increase of Granger causal influence from medial parietal lobe to cerebellum …

Parietal thalamocortical circuitry in global dream cessation
… cessation of dreaming is related to posterior parietal lesions. Two recent case reports (Bischof and Bassetti, 2004; Poza and Martí-Massó, 2006), in which patients with medial occipital lesions demonstrated total cessation of dreaming, cast doubt on this clinic-anatomical correlation, and the …

Individual Differences in Secondary Hyperalgesia and Associated Neural Activity
… Increased neural activity in the inferior parietal lobe and the premotor cortex during pain stimulation was associated with the development of larger areas of secondary hyperalgesia. Taken together, these findings suggest increased activation in brain regions contributing to multisensory …

Patterns of cognitive impairment in multiple sclerosis and their relationship to neuropathology on magnetic resonance imaging
… a lesion in the deep white matter of the left parietal lobe. The results support the hypothesis that MS results in multiple patterns of cognitive impairment depending on the individual placement of white matter lesions. Identifying and characterizing the heterogeneity of the impairment may …

Automatic Activation of Phonological Templates for Native but Not Nonnative Phonemes: An Investigation of the Temporal Dynamics of Mu Activation
… stream connecting the temporal and inferior parietal lobe with the inferior frontal gyrus. This stream is thought to involve an auditory-motor loop that translates acoustic information into motor/articulatory commands and is further influenced by decision making processes that involve …

Attention-Deficit/Hyperactivity Disorder (ADHD) and the influence of multisensory processes and sensorimotor integration on motor performance
… in Brodmann area (BA) 2, right-hemispheric parietal lobe, in response to multisensory input. This may be reflective of alterations related to attentional resources and sensory processing when multiple simultaneous inputs are presented, as is the case during a multisensory condition. …

Cortical location of saccadic and vergence oculomotor learning using fMRI
… and 3) the frontal eye fields within the frontal lobe had distinct areas of activity allocated for saccadic versus vergence eye movements. Activity was observed in the integration of oculo-motor functions and cognitive functions such as memory corresponding to the occipital lobe, the prefrontal …

The morphology of the intraparietal sulcus in children prenatally exposed to alcohol in a sample of children from the Western Cape, South Africa and its potential relationship with number processing
The intraparietal sulcus (IPS) is a prominent feature in the parietal lobe and extends posteriorly from the postcentral sulcus through the parietal lobe to end in the occipital. It is involved in visuospatial functions and is known to play a critical role in number processing. Fetal alcohol …

Parietal contributions to visual working memory depend on task difficulty
The nature of parietal contributions to working memory (WM) remain poorly understood but of considerable interest. We previously reported that posterior parietal damage selectively impaired WM probed by recognition (Berryhill & Olson, 2008a). Recent studies provided support using a neuromodulatory …

Neurostructural, Neurofunctional, and Neurocognitive Correlates of Cannabis Use in Adolescents with Bipolar Disorder
… group effects on brain structure in frontal and parietal regions. Adolescents with BD and cannabis use (BDCB+) exhibited larger volume and surface area (SA) in parietal regions, and smaller thickness in frontal regions, relative to healthy controls (HC) and adolescents with BD and no cannabis use …
