Deep Interpretability Methods for Neuroimaging

, 2022
Brain dynamics are highly complex and yet hold the key to understanding brain function and dysfunction. The dynamics captured by resting-state functional magnetic resonance imaging data are noisy, high-dimensional, and not readily interpretable.

Neuroimaging in Narcolepsy [PDF]

Sleep Medicine, 2010
Narcolepsy is a chronic neurological disorder, has no specific cause, and is characterized by excessive daytime sleepiness and uncontrollable sleep attacks. In case of strong emotions such as laughter, anger or joy, a cataplexy (sudden loss of muscle tone, lasting for a short period of time) may occur (1, 2).

Neuroimaging in Dementia [PDF]

Seminars in Neurology, 2008
Although dementia is a clinical diagnosis, neuroimaging often is crucial for proper assessment. Magnetic resonance imaging (MRI) and computed tomography (CT) may identify nondegenerative and potentially treatable causes of dementia. Recent neuroimaging advances, such as the Pittsburgh Compound-B (PIB) ligand for positron emission tomography imaging in ...

Atypical connectivity in the cortico-striatal network in NF1 children and its relationship with procedural perceptual-motor learning and motor skills

Journal of Neurodevelopmental Disorders, 2022
Introduction Neurofibromatosis type 1 (NF1) is considered a model of neurodevelopmental disorder because of the high frequency of learning deficits, especially developmental coordination disorder.

Confidence drives a neural confirmation bias

Nature 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]

Neurology, 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]

, 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 ...

Self-Conscious Emotions and the Right Fronto-Temporal and Right Temporal Parietal Junction

Brain Sciences, 2022
For more than two decades, research focusing on both clinical and non-clinical populations has suggested a key role for specific regions in the regulation of self-conscious emotions.
