AxonDeepSeg: automatic axon and myelin segmentation from
2018年2月28日 · AxonDeepSeg features: (i) a convolutional neural network architecture; (ii) an easy training procedure to generate new models based on manually-labelled data and (iii) two ready-to-use models...
Neuron under Microscope with Labeled Diagram - AnatomyLearner
2022年3月31日 · The axon branches at the right angle in the axon course and give the collateral branches. You will find the microtubules, neurofilaments, mitochondria, and smooth endoplasmic reticulum in the axoplasm. The axon can regenerate conditions and …
Spectral Reflectometric Microscopy on Myelinated Axons In Situ
2018年7月2日 · In a mammalian nervous system, myelin provides an electrical insulation by enwrapping the axon fibers in a multilayered spiral. Inspired by its highly-organized subcellular architecture, we recently developed a new imaging modality, named spectral reflectometry (SpeRe), which enables unprecedented label-free nanoscale imaging of the live ...

Axons contain two prominent cytoskeletal elements: microtubules and neurofilaments. Microtubules provide tracks along which material is transported to and from the cell body. Neurofilaments are a class of intermediate filaments and provide structural support. This EM image reveals a synapse between an axon and dendrite.
Mapping of individual sensory nerve axons from digits to spinal …
2024年1月3日 · With a confocal microscope and a 40×/1.3 numerical aperture objective, we achieved a uniform sub-micron resolution in the whole sample to reveal a complete projection of individual nerve axons...
3 Under the microscope: cells of the nervous system - University …
The axon begins at the axon hillock and ends at the presynaptic terminal, which can branch into multiple terminals. The basic form of a neuron is shown in Fig 2.24. It has a cell body, or soma, with branching processes called dendrites and a thin process called an axon. The axon can also be branched, forming axon collaterals.
Three dimensional electron microscopy reveals changing axonal …
2018年3月5日 · We used serial block face scanning electron microscopy (SBF SEM) to undertake 3D reconstruction of axons and myelin, analysing optic nerves from normal uninjured female rats and following partial...
A semi-automated method for identifying and measuring myelinated nerve ...
2011年9月30日 · We developed a morphological segmentation algorithm to analyze nerve images. Our algorithm automatically identifies and measures axons and surrounding myelin. Manual input allows removal of misidentified axons and addition of missed axons. Our algorithm is conceptually simple, easy to implement, and time-efficient. 1. Introduction.
AxCaliber: A Method for Measuring Axon Diameter Distribution …
Here we propose a new NMR-based approach that employs a model of water diffusion within “restricted” cylindrical axons to estimate their diameter distribution within a nerve bundle. This approach can be combined with MRI to furnish an estimate …
3D Axon Structure Extraction and Analysis in Confocal …
In these studies, researchers use triple immunofluorescent confocal microscopy to record morphological changes of neuronal processes. Three-dimensional (3D) microscopy image analysis is then required to extract morphological features of the neuronal structures.
