Age and Family History of Alzheimer's Disease and Related Dementias as Predictors of Locus Coeruleus and Salience Network Connectivity
… in the brain. The LC interacts with the salience network (SN), specifically the dorsal anterior cingulate cortex (dACC) and the insula, to coordinate and direct attention. The LC is a site of early Alzheimer's pathology and also experiences normal age-related declines in functioning. In …

Altered Brain Networks In Patients with Psychogenic Non-Epileptic Seizures (PNES) Using Ultra High Field MRI
… of PNES by helping better understand brain networks in patients with PNES. This study examines brain networks in patients with PNES with a focus on the default mode network and salience network. Methods: Twelve patients with PNES between the ages of 18-56 and twelve age- and sex- matched …

The connection between the triple network model and locus coeruleus integrity in those exhibiting inattentive symptoms
… been understood within a cortical triple network model, abnormalities in which may be relate to dysfunction in either LC structure or function. To examine the possibility of LC alteration being associated with inattentive symptom report, a set of analyses have been performed. In the first …

Neuroimaging and neurocognitive assessment of PTSD and MDD in a South African community setting
… within and between cognitive control networks (salience network, dorsal attention network, and frontoparietal networks) and a default mode network were compared across the 4 groups. Neuroanatomical indices (cortical thickness, volume, and surface area) of 10 frontal cortical regions …

Salience and Frontoparietal Network Patterns in Children with Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
… functional connectivity. In specific, two brain networks have been implicated in these 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” …

The impact of emotional distraction on cognition: from basic brain responses to large-scale network interactions
… frontal regions associated with the default-mode network (DMN). Finally, these DMN regions showed increased functional connectivity with DES regions for negative compared with positive distraction. Study two investigated sex differences in the response to external emotional distraction and yielded …

Examining the Associations Between Puberty and Social Reorientation at the Neural Level
… that are associated with the social brain and salience network. There were no effects of relationship type (parents vs. friends) nor interaction with other variables in predicting neural response. Finally, activation in the superior temporal gyrus (STG) interacted with emotion to predict …

White matter connectivity, cognition, symptoms and genetic risk factors in Schizophrenia
… SFMH study. Secondly, we investigated specific networks from the structural connectome and their topological properties in both healthy controls and patients diagnosed with schizophrenia in the SFMH study. These networks were studied alongside cognition, clinical symptoms and polygenic risk …

Childhood Trauma And Emotion Processing Neurocircuitry
… regulation, and (3) altered within- and between-network connectivity of the salience network, involved in detecting and orienting attention to salient emotional stimuli. These neurological changes are accompanied by behavioral alterations: trauma-exposed youth have a lower ability to ignore …

Neuroimaging Depression Risk in a Sample of Never-Depressed Children
… cortex; Study 1), functional activity in salience processing regions (i.e., anterior insula) and reward processing (i.e., putamen) during critical maternal feedback (Study 2), and resting-state functional connectivity within the Central Executive Network and Salience Network (Study 3). I …

Resting-State Cerebral Perfusion Patterns: An Exploratory Factor Analysis of Single-Photon Emission Computed Tomography Clinical Data
Resting-state (RS) networks (neural regions demonstrating a temporal correlation when a person is not engaged in deliberate activity) are a new topic in neuroscience and neuropsychology, not gaining significant traction in the literature until 2005. Few studies have used single-photon emission …

Factors Affecting Resting-State Functional Connectivity Across Three Intrinsically Connected Networks in Traumatic Brain Injury
… within three intrinsically connected networks; the default mode network (DMN), central executive network (CEN), and salience network (SN). The aim was to develop a predictive model for each network, based off a combination of cognitive performance, brain volumetric factors, …

Connectivity biomarkers in neurodegenerative tauopathies
… and how the anatomical and neurochemical networks that underlie clinical features might be altered by disease. I investigate simple clinical biomarkers, showing that a two-minute test of verbal fluency is a potential diagnostic biomarker to distinguish between PD and PSP and that the ACE-R …

The influence and manipulation of resting-state brain networks in alcohol use disorder
… in the signature of large-scale, dynamic brain networks, which can show whether an intervention is effective. One such intervention is episodic future thinking, which has been shown to reduce delay discounting and orient people toward pro-social, long-term outcomes. To better understand decision …

Meditation Techniques and Their Relationship to Psychotic-Like and Mystical Experiences
… activity in the orbitofrontal cortex (reward/salience), anterior cingulate (salience/cognitive control), and dorsolateral prefrontal cortex (inhibitory control).<br/><br/>In summary, in contrast to predictions, there was only weak agreement between results from a correlational survey and an …

Multisensory Integration in adults with Attention-Deficit/Hyperactivity Disorder
… ADHD is currently considered as a network disorder with alterations in the task-negative default mode network, the salience network, and the attentional control network. Despite the core symptoms, ADHD is characterized by sensory processing alterations in the sensory modalities, …
