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.

Simultaneous EEG-fMRI: What Have We Learned and What Does the Future Hold?
Italian National Conference on Sensors, 2022 Simultaneous EEG-fMRI has developed into a mature measurement technique in the past 25 years. During this time considerable technical and analytical advances have been made, enabling valuable scientific contributions to a range of research fields.

Spatio-Temporal Graph Convolution for Resting-State fMRI Analysis [PDF]
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2020 The Blood-Oxygen-Level-Dependent (BOLD) signal of resting-state fMRI (rs-fMRI) records the temporal dynamics of intrinsic functional networks in the brain.

fMRI adaptation revisited [PDF]
Cortex, 2016 Adaptation has been widely used in functional magnetic imaging (fMRI) studies to infer neuronal response properties in human cortex. fMRI adaptation has been criticized because of the complex relationship between fMRI adaptation effects and the multiple neuronal effects that could underlie them.

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.

A review of resting-state fMRI and its use to examine psychiatric disorders
Psychoradiology, 2021 Resting-state fMRI (rs-fMRI) has emerged as an alternative method to study brain function in human and animal models. In humans, it has been widely used to study psychiatric disorders including schizophrenia, bipolar disorder, autism spectrum disorders ...

Increased fMRI connectivity upon chemogenetic inhibition of the mouse prefrontal cortex
Nature Communications, 2022 While shaped and constrained by axonal connections, fMRI-based functional connectivity reorganizes in response to varying interareal input or pathological perturbations.

A New Rehabilitative Mechanism in Primary Motor Cortex After Peripheral Trauma
Frontiers in Neurology, 2020 Homuncular organization, i.e., the neuronal representation of the human body within the primary motor cortex, is one of the most fundamental principles of the human brain.

Frontiers in Human Neuroscience, 2013 Anatomical, morphological and histological data have consistently shown that the cingulate cortex can be divided into four main regions. However, less is known about parcellations of the cingulate cortex when involved in active tasks.

European Radiology, 2009 Several different techniques allow a functional assessment of neuronal activations by magnetic resonance imaging (fMRI). The by far most influential fMRI technique is based on a local T2*-sensitive hemodynamic response to neuronal activation, also known as the blood oxygenation level dependent or BOLD effect. Consequently, the term 'fMRI' is often used
