Disruption of Semantic Network in Mild Alzheimer’s Disease Revealed by Resting-State fMRI
Subtle semantic deficits can be observed in Alzheimer’s disease (AD) patients even in the early stages of the illness. In this work, we tested the hypothesis that the semantic control network isExpand

Brain Networks Underlying Eye’s Pupil Dynamics
Phasic changes in eye’s pupil diameter have been repeatedly observed during cognitive, emotional and behavioral activity in mammals. Although pupil diameter is known to be associated withExpand

Intrinsic Patterns of Coupling between Correlation and Amplitude of Low-Frequency fMRI Fluctuations Are Disrupted in Degenerative Dementia Mainly due to Functional Disconnection
Low frequency fluctuations (LFFs) of the BOLD signal are a major discovery in the study of the resting brain with functional magnetic resonance imaging (fMRI). Two fMRI-based measures, functionalExpand

Multi-modal Brain MRI in Subjects with PD and iRBD
Idiopathic rapid eye movement sleep behavior disorder (iRBD) is a condition that often evolves into Parkinson's disease (PD). Therefore, by monitoring iRBD it is possible to track theExpand

Scale-invariant rearrangement of resting state networks in the human brain under sustained stimulation
TLDR
We found that the transition from the resting state to the task state involves a behaviourally relevant and scale‐invariant modulation of synchronization patterns within both task‐positive and default mode networks, which correspond to physiologically relevant brain networks. Expand

Task-Related Modulations of BOLD Low-Frequency Fluctuations within the Default Mode Network
TLDR
We found that task execution impacted on both functional connectivity and amplitude of BOLD fluctuations within large parts of the DMN, but these changes correlated between each other only in a small area of the posterior cingulate. Expand

Influence of Repetitive Transcranial Magnetic Stimulation on Human Neurochemistry and Functional Connectivity: A Pilot MRI/MRS Study at 7 T
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation method commonly used in the disciplines of neuroscience, neurology, and neuropsychiatry to examine or modulateExpand

Assessing denoising strategies to increase signal to noise ratio in spinal cord and in brain cortical and subcortical regions
Functional Magnetic Resonance Imaging (fMRI) based on Blood Oxygenation Level Dependent (BOLD) contrast has become one of the most powerful tools in neuroscience research. On the other hand, fMRIExpand

Temporal Information Entropy of the Blood-Oxygenation Level-Dependent Signals Increases in the Activated Human Primary Visual Cortex
Time-domain analysis of blood-oxygenation level-dependent (BOLD) signals allows the identification of clusters of voxels responding to photic stimulation in primary visual cortex (V1). However, theExpand
