Neural basis of private and social decision-making: new insights from transcranial ultrasound stimulation and multivariate analysis
… integration of decision variables and that the precuneus/posterior cingulate cortex (PCC) is involved in the anticipation of regret, but not in its experience. We also found that social comparison is supported only by posterior brain areas, including the temporoparietal junction (TPJ), the …

The Neural Correlates of Spatial Language
… region in bilateral parietal cortex, the precuneus, was significantly active during spatial language processing. In a second experiment, there was a significant difference in the stroke population, with patients being more likely to perform better on the spatial condition of the task …

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
… treatment, lower RSFC in 2 clusters in the precuneus within the Default Mode Network (DMN) and the Ventral Attention Network were found in the TA with PT group compared to the TA only and SA with PT groups. No significant differences in mean Z-scores within these two clusters were seen among …

Where Does it Stem From? - Functional Neuroimaging of Monoaminergic Brainstem Nuclei in Altered States of Consciousness: Translational, Diagnostic and Therapeutic Implications
… disrupted from the main node of the DMN in the precuneus/posterior cingulate cortex, revealing a connectivity impairment universal to both ASCs. The extent of this VTA connectivity impairment was associated with DMN disconnectivity, as well as behaviour and/or outcome measures. Furthermore, I …

The Effect of Intranasal Oxytocin on Neural Functioning in Widow(er)s
… activation in right inferior frontal gyrus, the precuneus, and right superior temporal sulcus (STS). During INT OT, the CG group uniquely demonstrated slowed reaction time across all stimulus types. The NCG group during INT OT showed increased activation in the superior temporal sulcus (STS) and …

Emotional and Cognitive Influences on Visual Search
… connectivity to the inferior parietal lobule and precuneus, both of which are involved in the frontoparietal network. Comparison of fearful and happy functional connectivity patterns revealed higher V1 and V2 connectivity with medial frontal gyrus and anterior cingulate during the fearful …

Heading Disorientation in Amnestic Mild Cognitive Impairment is Correlated with Hypometabolism in the Posterior Cingulate Cortex
… A correlated with 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 …

Concussion Recovery and Skilled Performance in Working-Aged Adults: Sex Differences in the Neural Correlates of Persisting Symptoms After Concussion
… and superior frontal), thinner cortex (left precuneus), greater RPQ-3 symptom severity, and lower RSFC across multiple brain networks. Regression showed female sex and older age predicted poorer CMI performance. Findings highlight sex- and age-related neural factors underlying post-concussion …

Functional MRI Activation of Inhibitory Control in Adolescents and Young Adults with Multiple Sclerosis
… lateral occipital cortex, 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 …

Integrating Psychology and Neuroscience Approaches to Optimize Physical Activity Behavior Change
… clusters in the 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 …

Cerebrale Korrelate der selektiven Aufmerksamkeit bei schizophrenen Patienten mit formalen Denkstörungen : eine kontrollierte H2 15O-PET-Studie
… by significant activations in fusiform gyrus and precuneus. We suggest that differing task-solving strategies are applied by the two patient groups to achieve comparable results on the selective attention paradigm.

Parietal dysfunction in children with prenatal alcohol exposure
… reduced activation during place learning in the precuneus and posterior cingulate, as well as parahippocampal gyrus, frontal and temporal lobes, caudate, insula, claustrum, lentiform nucleus and thalamus. In girls, prenatal alcohol exposure was not associated with place learning performance or …

Neural Dysfunction during Decision-Making as a Predictor of Cocaine Relapse
… relapse. The fMRI activation patterns in the precuneus, bilateral orbitofrontal cortex, left insula, right dorsolateral prefrontal cortex, paracingulate, left hippocampus, and bilateral amygdala correctly classified 71% of patients by short-term and long-term relapse. This investigation …

Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis
… indicated the cingulate cortex, and the precuneus as the underlying sources of this ultra-late potential. In Paper II, using magnetoencephalography (MEG) to spatially track brain activations in response to brush stroking over time, we showed that Aβ afference rapidly activates a …

Bridging the link between trauma, brain development and depression: epigenetic mechanisms
… (1a) depressed adolescents had decreased left precuneus volume and greater volume of the left precentral gyrus compared to controls; however, no differences in fronto-limbic morphology were identified. Moreover, (1b) individuals with depression had lower levels of FKBP5 methylation than …

Impact of Exercise on Brain Responses to Visual Food Cues: An fMRI Study
