The mechanisms of tinnitus: perspectives from human functional neuroimaging [PDF]

open access: yes, 2009
In this review, we highlight the contribution of advances in human neuroimaging to the current understanding of central mechanisms underpinning tinnitus and explain how interpretations of neuroimaging data have been guided by animal models.

Functionally distinct contributions of the anterior and posterior putamen during sublexical and lexical reading

open access: yesFrontiers in Human Neuroscience, 2013
Previous studies have investigated orthographic-to-phonological mapping during reading by comparing brain activation for (1) reading words to object naming, or (2) reading pseudowords (e.g. phume) to words (e.g. plume).

Fast identification of biological pathways associated with a quantitative trait using group lasso with overlaps. [PDF]

open access: yes, 2012
Where causal SNPs (single nucleotide polymorphisms) tend to accumulate within biological pathways, the incorporation of prior pathways information into a statistical model is expected to increase the power to detect true associations in a genetic ...

Confidence drives a neural confirmation bias

open access: yesNature Communications, 2020
People often ignore evidence that disconfirms their prior beliefs. Here, the authors investigate the underlying cognitive, computational and neuronal mechanisms of such confirmation bias, and show that high confidence induces a selective neural ...

Capacity and tendency: A neuroscientific framework for the study of emotion regulation. [PDF]

open access: yes, 2019
It is widely accepted that the ability to effectively regulate one's emotions is a cornerstone of physical and mental health. As such, it should come as no surprise that the number of neuroimaging studies focused on emotion regulation and associated ...

Contextual perception under active inference

open access: yesScientific Reports, 2021
Human social interactions depend on the ability to resolve uncertainty about the mental states of others. The context in which social interactions take place is crucial for mental state attribution as sensory inputs may be perceived differently depending

Acute-stress-induced change in salience network coupling prospectively predicts post-trauma symptom development

open access: yesTranslational Psychiatry, 2022
Substantial individual differences exist in how acute stress affects large-scale neurocognitive networks, including salience (SN), default mode (DMN), and central executive networks (CEN). Changes in the connectivity strength of these networks upon acute

Excitatory Dorsal Lateral Prefrontal Cortex Transcranial Magnetic Stimulation Increases Social Anxiety

open access: yesBrain Sciences, 2023
Social exclusion refers to the experience of rejection by one or more people during a social event and can induce pain-related sensations. Cyberball, a computer program, is one of the most common tools for analyzing social exclusion. Regions of the brain

1st INCF Workshop on NeuroImaging Database Integration [PDF]

open access: yes, 2008
The goal of this meeting was to map existing neuroimaging databases, particularly databases containing primary data, and to identify mechanisms that could facilitate integrated use of such databases, including possible fusion of databases.

Teaching NeuroImages: Neuroimaging in hemiplegic migraine [PDF]

open access: yesNeurology, 2019
A 31-year-old man with hemiplegic migraine presented with a 2-day history of severe right-sided throbbing headache, photophobia, and vomiting. They were associated with numbness and weakness of the left hand, which spread to his left face and left leg. Brain MRI (figure) revealed cortical swelling involving the right temporoparietal occipital region (A)
