Bidirectional learning in upbound and downbound microzones of the cerebellum

CI De Zeeuw - Nature Reviews Neuroscience, 2021 - nature.com
Over the past several decades, theories about cerebellar learning have evolved. A relatively
simple view that highlighted the contribution of one major form of heterosynaptic plasticity to …

Acute cerebellar inflammation and related ataxia: mechanisms and pathophysiology

MSA Parvez, G Ohtsuki - Brain sciences, 2022 - mdpi.com

[HTML][HTML] Purkinje-cell-specific MeCP2 deficiency leads to motor deficits and autistic-like behavior due to aberrations in PTP1B-TrkB-SK signaling

FX Xu, XT Wang, XY Cai, JY Liu, JW Guo, F Yang… - Cell Reports, 2023 - cell.com
Patients with Rett syndrome suffer from a loss-of-function mutation of the Mecp2 gene, which
results in various symptoms including autistic traits and motor deficits. Deletion of Mecp2 in …

Behavioral tests for mouse models of autism: an argument for the inclusion of cerebellum-controlled motor behaviors

DH Simmons, HK Titley, C Hansel, P Mason - Neuroscience, 2021 - Elsevier
Abstract Mouse models of Autism Spectrum Disorder (ASD) have been interrogated using a
variety of behavioral tests in order to understand the symptoms of ASD. However, the …

Intrinsic and synaptic determinants of receptive field plasticity in Purkinje cells of the mouse cerebellum

TF Lin, SE Busch, C Hansel - Nature Communications, 2024 - nature.com
Non-synaptic (intrinsic) plasticity of membrane excitability contributes to aspects of memory
formation, but it remains unclear whether it merely facilitates synaptic long-term potentiation …

Population coding in the cerebellum: a machine learning perspective

R Shadmehr - Journal of neurophysiology, 2020 - journals.physiology.org
The cerebellum resembles a feedforward, three-layer network of neurons in which the
“hidden layer” consists of Purkinje cells (P-cells) and the output layer consists of deep …

cAMP− EPAC− PKCε− RIM1α signaling regulates presynaptic long-term potentiation and motor learning

XT Wang, L Zhou, BB Dong, FX Xu, DJ Wang… - Elife, 2023 - elifesciences.org
The cerebellum is involved in learning of fine motor skills, yet whether presynaptic plasticity
contributes to such learning remains elusive. Here, we report that the EPAC-PKCε module …
