Cerebellum: an explanation for dystonia? [PDF]

open access: yes, 2017
Dystonia is a movement disorder that is characterized by involuntary muscle contractions, abnormal movements and postures, as well as by non-motor symptoms, and is due to abnormalities in different brain areas.

Timing and Predictive Value of Clinical Conditions Preceding Multiple Sclerosis in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Multiple sclerosis (MS) patients often experience a higher incidence of clinical conditions before diagnosis, suggesting a prodromal phase. However, their predictive value and temporal trajectories remain underexplored. We investigated these aspects using the large UK Biobank's population‐based cohort, which provided clinical ...

Spatio-temporal dynamics of large-scale electrophysiological networks during cognitive action control in healthy controls and Parkinson's disease patients

open access: yesNeuroImage, 2022
Among the cognitive symptoms that are associated with Parkinson's disease (PD), alterations in cognitive action control (CAC) are commonly reported in patients. CAC enables the suppression of an automatic action, in favor of a goal-directed one.

Exploring the cognitive and motor functions of the basal ganglia: An integrative review of computational cognitive neuroscience models

open access: yesFrontiers in Computational Neuroscience, 2013
Many computational models of the basal ganglia have been proposed over the past twenty-five years. While computational neuroscience models have focused on closely matching the neurobiology of the basal ganglia, computational cognitive neuroscience models

Volumetric segmentation of multiple basal ganglia structures [PDF]

open access: yes, 2009
We present a new active contour-based, statistical method for simultaneous volumetric segmentation of multiple subcortical structures in the brain. Neighboring anatomical structures in the human brain exhibit co-dependencies which can aid in segmentation,

Isolation, characterization, and substrate properties of the external limiting membrane from the avian embryonic optic tectum [PDF]

open access: yes, 1990
The external limiting membrane of the avian embryonic optic tectum is isolated by mechanically separating the neuronal mesencephalon from the overlying mesenchymal tissue.

Clinical Characteristics of Parkinsonism in HTLV‐1‐Associated Myelopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Human T‐lymphotropic virus type 1 (HTLV‐1)‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the classic neurological manifestation of HTLV‐1 infection; however, this virus has also been associated with other neurological disorders. Concurrent parkinsonism is relatively rare and presents diagnostic challenges.

The basal ganglia

open access: yes, 2020
AbstractThe basal ganglia include the striatum (caudate, putamen, and ventral striatum) which receive from all cortical areas, and which project via the globus pallidus and substantia nigra back to the neocortex. The basal ganglia are implicated in stimulus-response habit learning, which may be provided by a reinforcement learning signal received by ...

Thalamic interaction between the input and the output systems of the basal ganglia [PDF]

open access: yes, 1999
The striatal return through the thalamus is largely neglected in current studies dealing with basal ganglia function, and its role within this circuitry remains obscure.

Understanding Mechanisms of Whole Brain and Regional Grey Matter Atrophy in Children With MOGAD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate the mechanisms driving whole brain and regional grey matter (GM) volume changes along with their clinical correlates in paediatric myelin oligodendrocyte glycoprotein antibody (MOG‐Ab)–associated disease (MOGAD). Methods One‐hundred‐nine paediatric MOGAD patients from two UK centres underwent MRI at attack nadir and ...
