Nucleus accumbens functional connectivity discriminates medication-overuse headache
NeuroImage: Clinical, 2016 Medication-overuse headache (MOH) is a secondary form of headache related to the overuse of triptans, analgesics and other acute headache medications. It is believed that MOH and substance addiction share some similar pathophysiological mechanisms.

Gray matter alterations in chronic pain: A network-oriented meta-analytic approach
NeuroImage: Clinical, 2014 Several studies have attempted to characterize morphological brain changes due to chronic pain. Although it has repeatedly been suggested that longstanding pain induces gray matter modifications, there is still some controversy surrounding the direction ...

DPARSF: A MATLAB Toolbox for “Pipeline” Data Analysis of Resting-State fMRI
Frontiers in Systems Neuroscience, 2010 Resting-state functional magnetic resonance imaging (fMRI) has attracted more and more attention because of its effectiveness, simplicity and non-invasiveness in exploration of the intrinsic functional architecture of the human brain.

Node Detection Using High-Dimensional Fuzzy Parcellation Applied to the Insular Cortex
Neural Plasticity, 2016 Several functional connectivity approaches require the definition of a set of regions of interest (ROIs) that act as network nodes. Different methods have been developed to define these nodes and to derive their functional and effective connections, most

What scans see when patients see defects: neuroimaging findings in body dysmorphic disorder
Journal of Integrative Neuroscience, 2022 Body dysmorphic disorder (BDD) is characterized by an individual's preoccupation with a perceived defect in their appearance which to others may be barely noticeable or even completely unnoticed.

FMRI Clustering in AFNI: False-Positive Rates Redux [PDF]
Brain Connectivity, 2017 Recent reports of inflated false-positive rates (FPRs) in FMRI group analysis tools by Eklund and associates in 2016 have become a large topic within (and outside) neuroimaging.

Optimizing Stimulation and Analysis Protocols for Neonatal fMRI [PDF]
, 2014 The development of brain function in young infants is poorly understood. The core challenge is that infants have a limited behavioral repertoire through which brain function can be expressed.
