Functional Connectivity of the Posterior Cingulate in Mild Cognitive Impairment and Alzheimer's Disease
… that reduced connectivity between the posterior cingulate cortex (PCC) and associated brain regions may make an important contribution in this regard, as changes in the PCC/precuneus and entorhinal cortex are implicated as early biomarkers for AD. The current study used functional connectivity …

Heading Disorientation in Amnestic Mild Cognitive Impairment is Correlated with Hypometabolism in the Posterior Cingulate Cortex
… hypometabolism in bilateral precuneus, posterior cingulate gyri, right crus cerebelli, cerebellar vermis, right anterior and middle cingulate gyri, right superior and middle frontal gyri, left inferior parietal region, and the left angular gyrus. (uncorrected p<0.05). Decrease in scores of part B …

Emotion, Depression, and Asymmetric Brain Function
… were also identified in amygdala and posterior cingulate gyrus. These findings confirm that emotional stimuli and trait depression are associated with asymmetric brain functions that are likely to go undetected unless appropriate data analytic procedures are used.

Exploration of the influence of emotionally primed environments on creativity and related patterns of brain activity
… dorsolateral prefrontal cortex (DLPFC), anterior cingulate gyrus (ACC), and anterior insula are active under both stimuli associated with increased divergent thinking. Future work is needed to investigate specifically how these brain regions may affect creativity and design cognition and whether …

The structural neurobiology of social anxiety disorder : a clinical neuroimaging study
… cortical thinning in the left isthmus of the cingulate gyrus, the left temporal pole, and the left superior temporal gyrus. Analyses of white matter tractographic data demonstrated reduced FA in in the genu, splenium and tapetum of the corpus callosum. Additionally reduced FA was noticed in …

Investigating reinforcement learning processes in depression and substance use disorder: translational, computational and neuroimaging approaches.
… connectivity from the amygdala to the anterior cingulate cortex, infralimbic cortex and insular cortex compared to males. The subsequent chapter uses a computational approach to investigate latent vulnerability variables in cocaine addiction. A longitudinal dataset acquired in rats was analysed, …

The Neural Correlates of Allocentric Spatial Memory in Schizotypy
… in the hippocampus and parahippocampal gyrus compared to controls. No behavioural differences were observed on the cognitive measures in this thesis. Investigation of brain function revealed decreased volume of the right hippocampus and bilateral medial frontal gyrus and increased volume …

Epigenetic Changes in Alzheimer’s and Huntington’sS Disease : A semi-quantitative analysis of histone changes
… histone changes in the inferior temporal gyrus and hippocampus of AD and the motor cortex, sensory cortex and cingulate gyrus of HD post mortem brains compared to age and sex matched neurologically normal control brains. Results obtained from semi-quantitative image analysis and Western …

Differences in resting state functional networks in HIV infected and uninfected children at age 7 years
… analysis (ICA) included the visual lingual gyrus, visual occipital gyrus, salience, dorsal attention, auditory, motor, executive control, posterior default mode network (pDMN) and default mode network (DMN) . No significant group level differences were found in any RSNs using ICA. However, …

Functional Role of the Cerebellar Vermis in Emotional Processing in Bipolar Disorder
… processing, specifically, the parahippocampal gyrus and cingulate gyrus. While we have gained a clearer understanding that these regions are functionally connected, we are still unclear of how these regions interact. Such an understanding can aide in the development of non-traditional uses for …

Integrating Psychology and Neuroscience Approaches to Optimize Physical Activity Behavior Change
… frontal pole region and the precuneus/posterior cingulate gyrus region. The frontopolar cortex is implicated in pre-commitment, a self-control strategy where people anticipate self-control failures and prospectively restrict their access to tempting alternatives. The precuneus/posterior cingulate …

Integration of multi-omic data and neuroimaging characteristics in studying brain related diseases
… areas in the brain, these are the left Heschl gyrus, right anterior cingulate gyrus, left fusiform gyrus and left Heschl gyrus, respectively. These potential association patterns could be useful for early disease diagnosis, treatment and neurodegeneration prediction. More importantly, we …

MEMORY AND DEFAULT NETWORK ACTIVATION AS A FUNCTION OF APOE GENOTYPE
… anterior portion of the left superior temporal gyrus, cingulate gyrus, and anterior middle frontal gyrus. This same pattern - greater APOE-ε4 carrier activation as compared to Non APOE-ε4 carriers - was present in the parahippocampal gyrus and posterior middle temporal gyrus during the judgment …

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
… regions 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 …

Exploring the relationship between multimodal magnetic resonance neuroimaging and cognitive outcomes in children: applying machine learning algorithms to brain MRI features to predict cognitive scores and performance categories of children living with and without HIV
… volume, diffusivity in the cingulum WM tract, cingulate gyrus area, and gyri-fication index of the parietal lobe. This suggests that multiple MRI modalities and fea-tures should be considered simultaneously to establish correlates of overall cognitive performance. The neural correlates we find …
