Selective attention involves a feature-specific sequential release from inhibitory gating

open access: yesNeuroImage, 2022
Selective attention is a fundamental cognitive mechanism that allows our brain to preferentially process relevant sensory information, while filtering out distracting information.

A Novel Joint Brain Network Analysis Using Longitudinal Alzheimer's Disease Data. [PDF]

open access: yes, 2019
There is well-documented evidence of brain network differences between individuals with Alzheimer's disease (AD) and healthy controls (HC). To date, imaging studies investigating brain networks in these populations have typically been cross-sectional ...

Shapley ratings in brain networks [PDF]

open access: yesFrontiers in Neuroinformatics, 2007
Recent applications of network theory to brain networks as well as the expanding empirical databases of brain architecture spawn an interest in novel techniques for analyzing connectivity patterns in the brain. Treating individual brain structures as nodes in a directed graph model permits the application of graph theoretical concepts to the analysis ...

Long-term moderate alcohol consumption does not exacerbate age-related cognitive decline in healthy, community-dwelling older adults

open access: yesFrontiers in Aging Neuroscience, 2015
Recent census data has found that roughly 40% of adults 65 years and older not only consume alcohol but also drink more of it than previous generations.

Psilocybin desynchronizes brain networks

open access: yes, 2023
1SummaryThe relationship between the acute effects of psychedelics and their persisting neurobiological and psychological effects is poorly understood. Here, we tracked brain changes with longitudinal precision functional mapping in healthy adults before, during, and for up to 3 weeks after oral psilocybin and methylphenidate (17 MRI visits per ...

Distinct patterns of temporal and directional connectivity among intrinsic networks in the human brain [PDF]

open access: yes, 2017
To determine the spatiotemporal relationships among intrinsic networks of the human brain, we recruited seven neurosurgical patients (four males and three females) who were implanted with intracranial depth electrodes.

Aging and functional brain networks [PDF]

open access: yesMolecular Psychiatry, 2011
Aging is associated with changes in human brain anatomy and function and cognitive decline. Recent studies suggest the aging decline of major functional connectivity hubs in the 'default-mode' network (DMN). Aging effects on other networks, however, are largely unknown.

Epileptic brain network mechanisms and neuroimaging techniques for the brain network

open access: yesNeural Regeneration Research, 2023
Epilepsy can be defined as a dysfunction of the brain network, and each type of epilepsy involves different brain-network changes that are implicated differently in the control and propagation of interictal or ictal discharges. Gaining more detailed information on brain network alterations can help us to further understand the mechanisms of epilepsy ...
