Functional Connectivity Density in Congenitally and Late Blind Subjects [PDF]
Cerebral Cortex, 2014 Visual deprivation during different developmental periods leads to different structural and functional alterations in the brain; however, the effects of visual deprivation on the spontaneous functional organization of the brain remain largely unknown. In this study, we used voxel-based functional connectivity density (FCD) analyses to investigate the ...

Dataset of whole-brain resting-state fMRI of 227 young and elderly adults acquired at 3T
Data in Brief, 2021 To investigate the impact of adult age on the brain functional connectivity, whole-brain resting-state functional magnetic resonance imaging (R-fMRI) data were acquired on a 3T clinical MRI scanner in a cohort of 227, right-handed, native Swedish ...

Feasibility of Reconstructing Source Functional Connectivity with Low-Density EEG [PDF]
Brain Topography, 2021 Abstract Objectives Functional connectivity (FC) is increasingly used as target for neuromodulation and enhancement of performance. A reliable assessment of FC with electroencephalography (EEG) currently requires a laboratory environment with high-density montages and a long preparation time.

Gender differences in brain functional connectivity density
Human Brain Mapping, 2011 AbstractThe neural bases of gender differences in emotional, cognitive, and socials behaviors are largely unknown. Here, magnetic resonance imaging data from 336 women and 225 men revealed a gender dimorphism in the functional organization of the brain. Consistently across five research sites, women had 14% higher local functional connectivity density (

On Connecting Density Functional Approximations to Theory
, 2022 Usually, density functional models are considered approximations to density functional theory, However, there is no systematic connection between the two, and this can make us doubt about a linkage. This attitude can be further enforced by the vagueness of the argumentation for using spin densities.
