The Pathoconnectivity Profile of Alzheimer’s Disease: A Morphometric Coalteration Network Analysis

Frontiers in Neurology, 2018
Gray matter alterations are typical features of brain disorders. However, they do not impact on the brain randomly. Indeed, it has been suggested that neuropathological processes can selectively affect certain assemblies of neurons, which typically are ...

Cuspis: A MATLAB Suite for Tasks Investigating Heart-Brain Interactions during fMRI

Journal of Open Research Software, 2023
Cuspis (Latin: [kuspis], meaning “sharp point”) is a MATLAB suite for presenting visual stimuli at different phases of the cardiac cycle and is designed to work with an MRI-compatible setup.

fMRI in the public eye [PDF]

Nature Reviews Neuroscience, 2005
The wide dissemination and expanding applications of functional MRI have not escaped the attention of the media or discussion in the wider public arena. From the bench to the bedside, this technology has introduced substantial ethical challenges. Are the boundaries of what it can and cannot achieve being communicated to the public?

Rest-fMRI—A Potential Substitute for Task-fMRI?

Indian Journal of Radiology and Imaging
Abstract Objective The aim of this study was to assess the reliability of resting-state functional magnetic resonance imaging (rest-fMRI) in mapping language areas for preoperative planning, versus standard task-based techniques, which are at times difficult to perform in clinical settings. Our study also aimed to evaluate the overlap between

Precision connectivity in osteoarthritis pain with permutation and network analysis: a key step toward clinical application

BMC Medical Imaging
Objective This study seeks to identify brain regions with atypical neural connectivity in individuals suffering from arthritis-related chronic pain, compared to healthy controls, using resting-state functional magnetic resonance imaging (rs-fMRI ...

Overview of fMRI analysis

The British Journal of Radiology, 2001
Abstract After an fMRI experiment has been designed and carried out, the resulting data must be passed through various analysis steps before the experimenter can get answers to questions about experimentally-related activations at the individual or multi-subject level.

Lidocaine patch (5%) is no more potent than placebo in treating chronic back pain when tested in a randomised double blind placebo controlled brain imaging study

Molecular Pain, 2012
Background The 5% Lidocaine patch is used for treating chronic neuropathic pain conditions such as chronic back pain (CBP), diabetic neuropathy and complex regional pain syndrome, but is effective in a variable proportion of patients.

fMRI-guided white matter connectivity in fluid and crystallized cognitive abilities in healthy adults

NeuroImage, 2020
This study examined within-subject differences among three fluid abilities that decline with age: reasoning, episodic memory and processing speed, compared with vocabulary, a crystallized ability that is maintained with age.

Dynamic models in fMRI [PDF]

Magnetic Resonance in Medicine, 2000
Most statistical methods for assessing activated voxels in fMRI experiments are based on correlation or regression analysis. In this context the main assumptions are that the baseline can be described by a few known basis-functions or variables and that the effect of the stimulus, i.e. the activation, stays constant over time. As these assumptions are
