Cerebellar Morphology and Behavioral Profiles in Mice Lacking Heparan Sulfate Ndst Gene Function

Journal of Developmental Biology, 2020
Disruption of the Heparan sulfate (HS)-biosynthetic gene N-acetylglucosamine N-Deacetylase/N-sulfotransferase 1 (Ndst1) during nervous system development causes malformations that are composites of those caused by mutations of multiple HS binding growth ...

Maturation of Purkinje cell firing properties relies on neurogenesis of excitatory neurons

eLife, 2021
Preterm infants that suffer cerebellar insults often develop motor disorders and cognitive difficulty. Excitatory granule cells, the most numerous neuron type in the brain, are especially vulnerable and likely instigate disease by impairing the function ...

A Novel Gain‐of‐Function ITPR1 Variant Associated With a Movement Disorder Characterized by Tremor and Dystonia

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The 1,4,5‐trisphosphate receptor type 1 (ITPR1) gene encodes an endoplasmic reticulum calcium release channel, in which loss‐of‐function mutations have been associated with spinocerebellar ataxias and related neurological phenotypes. Only one gain‐of‐function mutation in the highly conserved suppressor domain of ITPR1 has been previously ...

Logarithmic distributions prove that intrinsic learning is Hebbian

, 2017
In this paper, we present data for the lognormal distributions of spike rates, synaptic weights and intrinsic excitability (gain) for neurons in various brain areas, such as auditory or visual cortex, hippocampus, cerebellum, striatum, midbrain nuclei ...

mGlu1 Receptors Monopolize the Synaptic Control of Cerebellar Purkinje Cells by Epigenetically Down-Regulating mGlu5 Receptors [PDF]

, 2018
In cerebellar Purkinje cells (PCs) type-1 metabotropic glutamate (mGlu1) receptors play a key role in motor learning and drive the refinement of synaptic innervation during postnatal development.

Developmental Ethanol Exposure Impacts Purkinje Cells but Not Microglia in the Young Adult Cerebellum

Cells
Fetal alcohol spectrum disorders (FASD) caused by developmental ethanol exposure lead to cerebellar impairments, including motor problems, decreased cerebellar weight, and cell death.

The Reelin receptors Apoer2 and Vldlr coordinate the patterning of Purkinje cell topography in the developing mouse cerebellum. [PDF]

PLoS ONE, 2008
The adult cerebellar cortex is comprised of reproducible arrays of transverse zones and parasagittal stripes of Purkinje cells. Adult stripes are created through the perinatal rostrocaudal dispersion of embryonic Purkinje cell clusters, triggered by ...

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

Effect of intrauterine morphine sulfate exposure on cerebellar histomorphological changes in neonatal mice [PDF]

, 2011
Neurotoxic effects of morphine sulfate in adult cerebellar cortex and neonatal cerebral cortex have been studied in animal models. This study was done to determine the neurotoxic effects of prenatal morphine exposure on the histo morphological changes of

The cerebellum could solve the motor error problem through error increase prediction [PDF]

, 2015
We present a cerebellar architecture with two main characteristics. The first one is that complex spikes respond to increases in sensory errors. The second one is that cerebellar modules associate particular contexts where errors have increased in the ...
