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 ...

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)

Fast and accurate modelling of longitudinal and repeated measures neuroimaging data [PDF]

open access: yes, 2014
Despite the growing importance of longitudinal data in neuroimaging, the standard analysis methods make restrictive or unrealistic assumptions (e.g., assumption of Compound Symmetry—the state of all equal variances and equal correlations—or spatially ...

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

Neuroimaging in Essential Tremor [PDF]

open access: yes, 2013
Essential tremor (ET) is the most common movement disorder and one of the most frequent neurological disorders. The pathophysiological mechanisms responsible for generating the action tremors are poorly understood, and the diagnosis remains predominantly
