Using a novel source-localized phase regressor technique for evaluation of the vascular contribution to semantic category area localization in BOLD fMRI. [PDF]

, 2015
Numerous studies have shown that gradient-echo blood oxygen level dependent (BOLD) fMRI is biased toward large draining veins. However, the impact of this large vein bias on the localization and characterization of semantic category areas has not been ...

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Quantifying the Confidence in fMRI-Based Language Lateralisation Through Laterality Index Deconstruction

Frontiers in Neurology, 2019
In epilepsy patients, language lateralisation is an important part of the presurgical diagnostic process. Using task-based fMRI, language lateralisation can be determined by visual inspection of activity patterns or by quantifying the difference in left-

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Assessing Cerebral Dominance in the Geriatric Population: A Neuropsychological Perspective

Journal of the Indian Academy of Geriatrics
Cerebral dominance refers to the preferential engagement of one hemisphere of the brain – left or right – in specific cognitive operations. However, modern neuroscience asserts that cognitive functions are not confined to isolated hemispheres but ...

Taking sides with pain Lateralization aspects related to cerebral processing of dental pain

Frontiers in Human Neuroscience, 2011
The current fMRI study investigated cortical processing of electrically induced painful tooth stimulation of both maxillary canines and central incisors in 21 healthy, right handed volunteers. A constant current, 150% above tooth specific pain-perception

[18F]Fluorodeprenyl‐D2 PET as a Tool to Monitor Disease Activity in GAD65‐Ab Autoimmune Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate [18F]fluorodeprenyl‐D2 ([18F]F‐DED) positron‐emission tomography (PET) imaging as a biomarker of disease activity in autoimmune encephalitis (AIE) associated with glutamic acid decarboxylase 65 (GAD65) antibodies. Methods [18F]F‐DED PET was performed in 25 GAD65‐AIE patients and 8 controls using dynamic (0–60 min) and ...

The Impact of Functional Asymmetry of the Cerebral Hemispheres in Students of a Physics and Mathematics Lyceum on the Learning Outcomes

Journal of Vasyl Stefanyk Precarpathian National University
The functional asymmetry of the human brain hemispheres (motor, sensory, and mental) reflects the differences in the distribution of neuro-psychic functions between the left and right hemispheres.

A continuum of psychosis, one human gene, and not much else - the case for homogeneity [PDF]

, 1995
The contention of this paper is that psychoses are not a collection of separate and unrelated diseases, but a set of diverse expressions of a single underlying entity.
