Multiple Connection Pattern Combination From Single-Mode Data for Mild Cognitive Impairment Identification

Frontiers in Cell and Developmental Biology, 2021
Mild cognitive impairment (MCI) is generally considered to be a key indicator for predicting the early progression of Alzheimer’s disease (AD). Currently, the brain connection (BC) estimated by fMRI data has been validated to be an effective diagnostic ...

Excessively increased thalamocortical connectivity and poor initial antiseizure medication response in epilepsy patients

Frontiers in Neurology, 2023
ObjectivesThe network mechanism underlying the initial response to antiseizure medication in epilepsy has not been revealed yet. Given the central role of the thalamus in the brain network, we conducted a case-control study to investigate the association

What Is Lost During Dreamless Sleep: The Relationship Between Neural Connectivity Patterns and Consciousness

Journal of European Psychology Students, 2014
Non-rapid eye movement (NREM) sleep is characterised by reduced consciousness; thus, studying its neural characteristics acts as a useful indication of what is needed for conscious experience.

Reorganization of brain networks in aging: A review of functional connectivity studies.

Frontiers in Psychology, 2015
Healthy aging (HA) is associated with certain declines in cognitive functions, even in individuals that are free of any process of degenerative illness.

The Effect of Connectives on the Selection of Arguments: Implicit Consequentiality Bias for the Connective “but” [PDF]

Journal of Psycholinguistic Research, 2013
Recent studies about the implicit causality of inter-personal verbs showed a symmetric implicit consequentiality bias for psychological verbs. This symmetry is less clear for action verbs because the verbs assigning the implicit cause to the object argument (e.g.

Longitudinal prognosis of Parkinson’s outcomes using causal connectivity

NeuroImage: Clinical
Despite the prevalence of Parkinson’s disease (PD), there are no clinically-accepted neuroimaging biomarkers to predict the trajectory of motor or cognitive decline or differentiate Parkinson’s disease from atypical progressive parkinsonian diseases ...

Ketamine Psychedelic and Antinociceptive Effects Are Connected

Anesthesiology, 2022
Background Ketamine produces potent analgesia combined with psychedelic effects. It has been suggested that these two effects are associated and possibly that analgesia is generated by ketamine-induced dissociation. The authors performed a post hoc

Visualizing effective connectivity in the human brain

Brain Stimulation
Abstract To enhance mechanistic understanding of effective connectivity in the human brain, we created a tool that links high-temporal resolution transcranial magnetic stimulation electroencephalography (TMS-EEG) with high-spatial resolution diffusion MRI.

Identification of Effective Connectivity Subregions

CoRR, 2019
Standard fMRI connectivity analyses depend on aggregating the time series of individual voxels within regions of interest (ROIs). In certain cases, this spatial aggregation implies a loss of valuable functional and anatomical information about smaller subsets of voxels that drive the ROI level connectivity.
