Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Quantification of Cerebellar Hemispheric Purkinje Cell Linear Density: 32 ET Cases vs. 16 Controls

Movement Disorders, 2013
Although essential tremor (ET) is among the most prevalent neurological diseases, its precise pathogenesis is not understood. Purkinje cell loss has been observed in some studies and is the focus of interest and debate.

Phenotypic Exploration in Patients with Heterozygous Variant in AFG3L2 Gene: A Case‐Series and Literature Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Variants in AFG3‐Like Matrix AAA Peptidase, Subunit 2 (AFG3L2) gene are associated with diverse clinical phenotypes. Here, we describe phenotypic findings of two unrelated children with de novo heterozygous variant and one family with inherited heterozygous variant in AFG3L2 gene.

Regularity, variabilty and bi-stability in the activity of cerebellar Purkinje cells

Frontiers in Cellular Neuroscience, 2009
Recent studies have demonstrated that the membrane potential of Purkinje cells is bi-stable and that this phenomenon underlies bi-modal simple spike firing.

A Model of Cerebellar Adaptation of Grip Forces During Lifting [PDF]

, 2003
We investigated adaptive neural control of precision grip forces during object lifting. A model is presented that adjusts reactive and anticipatory grip forces to a level just above that needed to stabilize lifted objects in the hand.

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

Movement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Neurosteroid Biosynthesis and Action in the Purkinje Cell

Journal of Experimental Neuroscience, 2009
It is now clearly established that steroids can be synthesized de novo by the vertebrate brain. Such steroids are called neurosteroids. To understand neurosteroid action in the brain, data on the regio- and temporal-specific synthesis of neurosteroids ...

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Effect of gestational diabetes on purkinje and granule cells distribution of the rat cerebellum in 21 and 28 days of postnatal life [PDF]

, 2015
Introduction: Diabetes mellitus is associated with nervous system alterations in both human and animal models. This study was done to determine the effect of gestational diabetes on the Purkinje and granular cells in the cerebellum of rat offspring ...
