One-year changes in brain microstructure differentiate preclinical Huntington's disease stages

NeuroImage: Clinical, 2020
Objective: To determine whether brain imaging markers of tissue microstructure can detect the effect of disease progression across the preclinical stages of Huntington's disease. Methods: Longitudinal microstructural changes in diffusion imaging metrics (

Dynamic Relationship Between Interhemispheric Functional Connectivity and Corticospinal Tract Changing Pattern After Subcortical Stroke

Frontiers in Aging Neuroscience, 2022
Background and PurposeIncreased interhemispheric resting-state functional connectivity (rsFC) between the bilateral primary motor cortex (M1) compensates for corticospinal tract (CST) impairment, which facilitates motor recovery in chronic subcortical ...

Why musical memory can be preserved in advanced Alzheimer's disease [PDF]

, 2015
Musical memory is relatively preserved in Alzheimer's disease and other dementias. In a 7 Tesla functional MRI study employing multi-voxel pattern analysis, Jacobsen et al.

An approach for identifying brainstem dopaminergic pathways using resting state functional MRI. [PDF]

, 2014
Here, we present an approach for identifying brainstem dopaminergic pathways using resting state functional MRI. In a group of healthy individuals, we searched for significant functional connectivity between dopamine-rich midbrain areas (substantia nigra;

International Veterinary Epilepsy Task Force recommendations for a veterinary epilepsy-specific MRI protocol [PDF]

, 2015
Epilepsy is one of the most common chronic neurological diseases in veterinary practice. Magnetic resonance imaging (MRI) is regarded as an important diagnostic test to reach the diagnosis of idiopathic epilepsy.

Conditioned respiratory threat in the subdivisions of the human periaqueductal gray

eLife, 2016
The sensation of breathlessness is the most threatening symptom of respiratory disease. The different subdivisions of the midbrain periaqueductal gray (PAG) are intricately (and differentially) involved in integrating behavioural responses to threat in ...
