Simultaneous tDCS-fMRI Identifies Resting State Networks Correlated with Visual Search Enhancement

Frontiers in Human Neuroscience, 2016
This study uses simultaneous transcranial direct current stimulation tDCS and fMRI to investigate tDCS modulation of resting state activity and connectivity that underlies enhancement in behavioral performance.

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Modulation of functional connectivity during the resting state and the motor task [PDF]

, 2004
Quite a few studies in functional magnetic resonance imaging (fMRI) have tested that, even in a resting state, motor cortices constitute a network. It has never been investigated how the network modulates from the resting state to the motor task state ...

Multifractal Dynamic Functional Connectivity in the Resting-State Brain

Frontiers in Physiology, 2018
Assessing the functional connectivity (FC) of the brain has proven valuable in enhancing our understanding of brain function. Recent developments in the field demonstrated that FC fluctuates even in the resting state, which has not been taken into account by the widely applied static approaches introduced earlier.

Resting state functional connectivity of the striatum in Parkinson’s disease [PDF]

Brain, 2012
Classical accounts of the pathophysiology of Parkinson's disease have emphasized degeneration of dopaminergic nigrostriatal neurons with consequent dysfunction of cortico-striatal-thalamic loops. In contrast, post-mortem studies indicate that pathological changes in Parkinson's disease (Lewy neurites and Lewy bodies) first appear primarily in the lower

Examining resting-state functional connectivity in first-episode schizophrenia with 7T fMRI and MEG

NeuroImage: Clinical, 2019
Schizophrenia is often characterized by dysconnections in the brain, which can be estimated via functional connectivity analyses. Commonly measured using resting-state functional magnetic resonance imaging (fMRI) in order to characterize the intrinsic or

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Changes in structural and functional connectivity among resting-state networks across the human lifespan [PDF]

, 2014
At rest, the brain's sensorimotor and higher cognitive systems engage in organized patterns of correlated activity forming resting-state networks. An important empirical question is how functional connectivity and structural connectivity within and ...

Neural correlates of future‐oriented coping: Preliminary evidence from a resting‐state functional connectivity study [PDF]

, 2018
Future-oriented coping is a strategy for coping with events that may happen in the future, including efforts to ensure positive outcome and protection from potential threats.

Resting state functional connectivity in the human spinal cord

eLife, 2014
Functional magnetic resonance imaging using blood oxygenation level dependent (BOLD) contrast is well established as one of the most powerful methods for mapping human brain function. Numerous studies have measured how low-frequency BOLD signal fluctuations from the brain are correlated between voxels in a resting state, and have exploited these ...
