Parietal dysfunction in children with prenatal alcohol exposure
… this deficit by increased activation of the left angular gyrus during the proximity judgment task. Syndromal children with fetal alcohol syndrome or partial fetal alcohol syndrome also demonstrated poor recruitment of the right horizontal intraparietal sulcus during nonsymbolic number comparison, …

Effects of attention on the precision of neural and mnemonic representations in healthy ageing
… examine whether non-invasive stimulation to the angular gyrus enhances the quality of episodic representations. Results demonstrate that angular gyrus stimulation only enhanced retrieval error performance in younger adults but did not yield facilitatory effects on model-driven retrieval precision …

FMRI studies of effects of hearing status on audio-visual speech perception
… speech motor network areas, supramarginal gyrus, thalamus, superior parietal cortex and fusiform gyrus. For hearing impaired subjects, in addition to the areas listed above, Heschl's gyrus, right angular gyrus (AG), cerebellum and regions around right inferior frontal sulcus (IFS) in the …

Auditory comprehension: from the voice up to the single word level
… frontal cortex (likely ventral inferior frontal gyrus) leads to systematic voice perception deficits while left hemispheric lesions can elicit both voice and phoneme deficits. Together these results show that phoneme processing is lateralized while voice information processing requires both …

Cortical Processing of Visual Parts and Wholes
… in the right parietal lobe and superior temporal gyrus and bilaterally in the fusiform gyrus, suggesting a relation between holistic processing areas and object perception. Configural objects with many parts elicited increased activation in the left angular gyrus. This study, to our knowledge, is …

Characteristics of syntactic processing : an examination utilizing behavioral and fMRI techniques
… Activation was seen in portions of the angular gyrus and the middle temporal gyrus for a contrast in subject noun plausibility, but not structure ambiguity, indicating that the MV interpretation was still considered even in unambiguously relative clause sentence structures. The …

Large-scale Functional Connectivity in the Human Brain Reveals Fundamental Mechanisms of Cognitive, Sensory and Emotion Processing in Health and Psychiatric Disorders
… between thalamus and superior temporal gyrus, angular gyrus and hippocampus, and fusiform and amygdala, while informative features for subliminal fear perception included middle temporal gyrus, cerebellum and angular gyrus. In psychiatric disorders, large-scale functional connectivity is …

Changes in cerebral glucose metabolism in patients with Parkinson’s disease with dementia after cholinesterase inhibitor therapy
… metabolism in left superior / middle frontal gyrus and left inferior parietal gyrus, mainly angular gyrus. There was also a region of decreased glucose metabolism in right medial temporal cortex, including fusiform, parrahippocampal gyrus and hippocampus. The degree of improvement in MMSE …

Heading Disorientation in Amnestic Mild Cognitive Impairment is Correlated with Hypometabolism in the Posterior Cingulate Cortex
… left inferior parietal region, and the left angular gyrus. (uncorrected p<0.05). Decrease in scores of part B correlated with hypometabolism in bilateral precuneus, middle and posterior cingulate gyri (uncorrected p<0.005). CONCLUSION: The test scores of part B of the card placing test …

Effects of healthy ageing on the precision of episodic memory
… of memory retrieval were evident in the angular gyrus. Furthermore, at encoding, age-related decreases in activity predicting both later success and precision of memory retrieval were evident in the fusiform gyrus, while prefrontal reductions were observed in the encoding activity …

Behavioural and Neural Investigation of the Subjective Experience of Remembering
… modality to causally test whether the left angular gyrus (AnG) supports multimodal feature integration during episodic and semantic memory retrieval. Left AnG stimulation was found to selectively modulate response times in multimodal versus unimodal trials of both episodic associative …

Comparison of resting state functional networks in HIV infected and uninfected children at age 9 years
… (of the medial visual network) and the right angular gyrus (of the temporoparietal network). Finally, to left paracentral (somatosensory network) and right precuneus (posterior DMN) seeds previously revealing between-group differences at age 7 years. The connections with greater FC in HIV+ …

Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction
… contrasts of semantic variables; 2) ATL and Angular Gyrus (AG) acted as potential integrator hubs for integration of information produced in distributed semantic areas. This was observed using Dynamic Causal Modelling of connectivity among the main left-hemispheric candidate hubs and …

Functional brain imaging of facial emotion processing in individuals with intellectual impairments
… greater activation in the left supramarginal gyrus / angular gyrus in response to fearful facial stimuli compared to the autistic sub-group. This pattern of relative hypo-activation in individuals with autism to emotional stimuli is typical of the existing literature in autism and adds further …

The neurofunctional correlates of sentence processing: focus on difficulties of morphosyntactic processing and thematic role assignment in aphasia
… with damage to the superior and middle temporal gyrus and to the superior occipitolateral cortex. Both correlations persisted after covarying for phonological short-term memory. When response accuracy to passive vs active sentences in the presence of thematic foils was considered, portions of the …

MORE THAN FINGER COUNTING: SHARED RESOURCES BETWEEN FINGER TAPPING AND ARITHMETIC
Arithmetic is a branch of mathematics upon which many other mathematical content areas are built. The study of the mechanisms underlying arithmetic is crucial for understanding cognition in other domains of mathematics, as well as higher-level cognition. Recent advances in the study of embodied …

Neural Mechanisms Mediating the Effects of Food Cues and Acute Exercise: a functional Magnetic Resonance Imaging and Functional Connectivity Investigation
… the putamen, insula, operculae, inferior frontal gyrus, and superior parietal lobule and decreased coupling with the amygdala and orbital frontal cortex, among other areas. We believe this is the first study of exercise induced appetite suppression that used whole brain analysis and functional …

Potential benefits and neural correlates of acupuncture treatment with or without physiotherapy on resting state functional connectivity in ischemic stroke patients with unilateral limb dysfunction
… within three networks, including the cingulate gyrus and the precuneus in the DMN, the orbitofrontal cortex in the executive control network, and the inferior and superolateral occipital lobe in the visual network. In all five of these regions, patients receiving TA+PT showed a significantly …
