What is affected is the primary retinal ganglion cells (RGC) and the axons forming the optic nerve. The RGC and axons process visual information which begins as light entering the eye, which then gets transmitted to the brain. “Optic Atrophy” means that some or all of the nerve fibers ...
Brain atrophy essentially means that neurons and their connections to each other have undergone necrosis. The affected areas cannot function as they should.Wherethis occurs determines what symptoms you experience. Atrophy in the brain can be focal or generalized: Focal brain atrophyaffects one or more...
The poet: a sly devil who can torment himself at will, unearthing perplexities, obtaining them by every possible means. And afterward, naive posterity commiserates with him … 诗人:一个狡黠的魔鬼,仅凭喜好地折磨自己,挖掘困惑,尽一切所能地谋取它们。尔后,无知的后辈便开始献上他们的怜悯…… Almost...
What are the symptoms and signs of spinal muscular atrophy? Spinal muscular atrophy (SMA) manifests itself in various ways. Some SMA newborns are "floppy," which means they do not learn to roll or sit at the appropriate age. An older youngster may fall more frequently than younger children ...
These disorders are typically inherited and can vary in terms of onset and severity. Muscular atrophy, however, means the muscles are shrinking or wasting away, either because they're not being used (like when a limb is in a cast) or because of a medical condition that affects muscle ...
Explain how the process of atrophy could be accomplished. Atrophy This is the process of shrinking or making a tissue smaller in size. In biology, atrophy is typically associated with skeletal muscle loss. Although you are not actually losing muscle fibres, the diameter of each is shrunk to so...
we still do not know what amount of sleep is associated with good brain health and whether a causal relationship between variations in habitual sleep duration and brain health exists. Here we address these questions, analysing MRIs of the brain and genetic data in a combined longitudinal and cros...
Structural MRI pre-processing was performed using standard CAT pipelines, which included the initial application of a spatial adaptive non-local means denoising filter [30], followed by an internal resampling to deal with different resolution images and anisotropic spatial resolution between scanners. Th...

96 Fasciculation is not particularly common in this type of HMN, and the tendon reflexes may be depressed or absent in both HMN and myopathy of scapuloperoneal distribution. The electromyographic and histologic changes may by no means be unequivocal; in the patients reported by Merc...
