Phenotyping Superagers Using Resting-State fMRI

American Journal of Neuroradiology, 2023
Superagers are defined as older adults with episodic memory performance similar or superior to that in middle-aged adults. This study aimed to investigate the key differences in discriminative networks and their main nodes between superagers and cognitively average elderly controls.

A comparison of resting state functional magnetic resonance imaging to invasive electrocortical stimulation for sensorimotor mapping in pediatric patients

NeuroImage: Clinical, 2019
Localizing neurologic function within the brain remains a significant challenge in clinical neurosurgery. Invasive mapping with direct electrocortical stimulation currently is the clinical gold standard but is impractical in young or cognitively delayed ...

Resting State fMRI-Guided Fiber Clustering [PDF]

, 2011
Fiber clustering is a prerequisite step towards tract-based analysis of white mater integrity via diffusion tensor imaging (DTI) in various clinical neuroscience applications. Many methods reported in the literature used geometric or anatomic information for fiber clustering.

Group analysis data representing the effects of frontopolar transcranial direct current stimulation on the default mode network

Data in Brief, 2018
The current data provide information about altered activities of the default mode network (DMN) after applying transcranial direct current stimulation (tDCS) over the frontopolar prefrontal cortex. To explore whether frontopolar tDCS with a small current

Metodi per l'integrazione dell'informazione EEG nell'analisi fMRI in resting state [PDF]

, 2022
L’obiettivo della tesi è studiare la correlazione fra l’attività oscillatoria del ritmo alfa e il segnale BOLD in resting state. Si è impiegato un approccio asimmetrico combinando segnale EEG e fMRI.

On consciousness, resting state fMRI, and neurodynamics [PDF]

Nonlinear Biomedical Physics, 2010
During the last years, functional magnetic resonance imaging (fMRI) of the brain has been introduced as a new tool to measure consciousness, both in a clinical setting and in a basic neurocognitive research. Moreover, advanced mathematical methods and theories have arrived the field of fMRI (e.g.

Spatiotemporal nonlinearity in resting-state fMRI of the human brain

, 2008
In this work, the spatiotemporal nonlinearity in resting-state fMRI data of the human brain was detected by nonlinear dynamics methods. Nine human subjects during resting state were imaged using single-shot gradient echo planar imaging on a 1.5T scanner.

Altered regional homogeneity in pediatric bipolar disorder during manic state: a resting-state fMRI study. [PDF]

PLoS ONE, 2013
UNLABELLED: Pediatric bipolar disorder (PBD) is a severely debilitating illness, which is characterized by episodes of mania and depression separated by periods of remission. Previous fMRI studies investigating PBD were mainly task-related.
