optic pathway lesionsTo identify the components of the short latency visual evoked potentials (SVEP), five clinical cases with lesions in different parts of the optic pathway and visual cortex were studied comparatively. Optic nerve potentials were differentiated in the case of optic nerve astrocytoma...
where the pituitary glandsits, and near where the optic nerves travel from the eyes to the occiput in the back of the brain. As the tumor grows, it can push on the optic nerveand cause visual changes andblindness.
Visual field defects are a conglomerate of patterns of visual impairment derived from diseases affecting the optic nerve as it extends from the globe to the visual cortex. The anatomy of this region is complex, largely existing in pairs and consisting of the globes, optic nerve/sheath complexes,...
Because of their fixed coating, the spinal cord and the optic nerve are places where tissue swelling may cause not only demyelination but also tissue necroses. Despite this limitation, Prineas and McDonald [3] do not believe that tissue swelling plays a significant role in the development of ...
complex that probably accomplishes this contralateralization of the auditory field; and that, therefore, this structural complex serves the auditory system in a manner essentially analogous to the optic chiasma in the visual system or the spinal and bulbar decussations in the somatosensory systems....

The repair of inflamed, demyelinated lesions as in multiple sclerosis (MS) necessitates the clearance of cholesterol-rich myelin debris by microglia/macrophages and the switch from a pro-inflammatory to an anti-inflammatory lesion environment. Subsequently, oligodendrocytes increase cholesterol levels as...
1, i.e. a dual-pathway DCNN. For ISLES challenge, all CT sequences are resized to 160 × 160. We use images slices flipped and randomly rotated methods to augment the training images. In training process, the hyper- parameter kept constant: batch size is set to 4, epoch is set to ...
Neuromyelitis optica (NMO) shows various brain magnetic resonance imaging (MRI) abnormalities with recurrent central nervous system (CNS) attacks, although predominantly affecting the spinal cord and optic nerve. However, NMO with extensive involvement of the brain has infrequently been studied. We inves...
