Frontiers in Immunology, 2021 Normal aging is characterized by declines in processing speed, learning, memory, and executive function even in the absence of neurodegenerative diseases such as Alzheimer's Disease (AD). In normal aging monkeys and humans, neuronal loss does not account

AxonDeepSeg: automatic axon and myelin segmentation from microscopy data using convolutional neural networks [PDF]
, 2017 Segmentation of axon and myelin from microscopy images of the nervous system provides useful quantitative information about the tissue microstructure, such as axon density and myelin thickness. This could be used for instance to document cell morphometry

Astrocytes and Microglia as Major Players of Myelin Production in Normal and Pathological Conditions
Frontiers in Cellular Neuroscience, 2020 Myelination is an essential process that consists of the ensheathment of axons by myelin. In the central nervous system (CNS), myelin is synthesized by oligodendrocytes. The proliferation, migration, and differentiation of oligodendrocyte precursor cells

A Novel Lysolecithin Model for Visualizing Damage in vivo in the Larval Zebrafish Spinal Cord
Frontiers in Cell and Developmental Biology, 2021 Background: Lysolecithin is commonly used to induce demyelinating lesions in the spinal cord and corpus callosum of mammalian models. Although these models and clinical patient samples are used to study neurodegenerative diseases, such as multiple ...

Polyphosphoinositides in myelin [PDF]
Biochemical Journal, 1965 1. On fractionation of guinea-pig forebrain homogenates by differential and gradient-density centrifugation most of the polyphosphoinositides were recovered in the myelin-rich particles. 2. The phospholipids of pure preparations of myelin contained di- and tri-phosphoinositide in proportions 2-3 times greater than in the whole-brain phospholipids.

A Physical Perspective to the Inductive Function of Myelin—A Missing Piece of Neuroscience
Frontiers in Neural Circuits, 2021 Starting from the inductance in neurons, two physical origins are discussed, which are the coil inductance of myelin and the piezoelectric effect of the cell membrane.

Preliminary Evidence of Increased Hippocampal Myelin Content in Veterans with Posttraumatic Stress Disorder. [PDF]
, 2015 Recent findings suggest the formation of myelin in the central nervous system by oligodendrocytes is a continuous process that can be modified with experience.

CD36-mediated uptake of myelin debris by macrophages and microglia reduces neuroinflammation
Journal of Neuroinflammation, 2020 Background The presence of foamy macrophages and microglia containing intracellular myelin remnants is a pathological hallmark of neurodegenerative disorders such as multiple sclerosis (MS).

Myelin figures: the buckling and flow of wet soap
, 2009 Myelin figures are interfacial structures formed when certain surfactants swell in excess water. Here, I present data and model calculations suggesting myelin formation and growth is due to the fluid flow of surfactant, driven by the hydration gradient ...
