Quantification of volumetric morphometry and optical property in the cortex of human cerebellum at micrometer resolution

NeuroImage, 2021
The surface of the human cerebellar cortex is much more tightly folded than the cerebral cortex. Volumetric analysis of cerebellar morphometry in magnetic resonance imaging studies suffers from insufficient resolution, and therefore has had limited ...

Decreased density of pyramidal cells in the cerebral cortex, and Purkinje cells in the cerebellar cortex of Sprague-Dawley rats after being exposed to filtered kretek cigarette smoke

Journal of Biological Research, 2023
Filtered kretek cigarette smoke is a gas that contains solid components (particulates). Carcinogenic chemicals are present in this type of cigarette smoke. Furthermore, it is said that tobacco has a major negative impact on cerebral structure development,

EEG responses induced by cerebellar TMS at rest and during visuomotor adaptation

NeuroImage, 2023
Background: Connections between the cerebellum and the cortex play a critical role in learning and executing complex behaviours. Dual-coil transcranial magnetic stimulation (TMS) can be used non-invasively to probe connectivity changes between the ...

Diffusion spectrum imaging shows the structural basis of functional cerebellar circuits in the human cerebellum in vivo. [PDF]

PLoS ONE, 2009
The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits.

Principles of operation of a cerebellar learning circuit

eLife, 2020
We provide behavioral evidence using monkey smooth pursuit eye movements for four principles of cerebellar learning. Using a circuit-level model of the cerebellum, we link behavioral data to learning’s neural implementation.

Morphological features of the structure of the cerebellar cortex of rats in the norm and under prolonged exposure to the opioid

Zaporožskij Medicinskij Žurnal, 2015
In recent decades the issue of drug addiction has appeared to be not only a social, but medical problem. Aim. To establish peculiarities of the microstructure of the rat’s cerebellar cortex in the norm and to investigate changes in the structural ...

An anatomical and connectivity atlas of the marmoset cerebellum

Cell Reports, 2023
Summary: The cerebellum is essential for motor control and cognitive functioning, engaging in bidirectional communication with the cerebral cortex. The common marmoset, a small non-human primate, offers unique advantages for studying cerebello-cerebral ...

Stimulating Cerebellar Outflow Reveals Temporal Control of Motor Cortical Activity

Cell Reports, 2019
Nashef et al. (2019) show that high-frequency stimulation of the superior cerebellar peduncle produces a temporary cerebellar deficit. While the deficit is present, motor cortex neurons that receive cerebellar input maintain their directional tuning but ...

Low-intensity ultrasound directly modulates neural activity of the cerebellar cortex

Brain Stimulation, 2023
Background: Low-intensity ultrasound is a noninvasive neuromodulation technique with the potential to focally manipulate deep brain activity at millimeter-scale resolution. However, there have been controversies over the direct influence of ultrasound on

The Potential Ameliorative Effect of Vitamin C Versus Astaxanthin on Methotrexate Induced Damage in Rat Cerebellar Cortex: A Biochemical, Histological and Immunohistochemical Study [PDF]

The Egyptian Journal of Histology
Introduction: Methotrexate causes injury in the cerebellar cortex. Vitamin C is one of the most familiar antioxidant components. Astaxanthin may provide protection for the brain from reactive stress.
