WebGenetic mutations. Certain genetic mutations might increase your risk of developing optic neuritis or multiple sclerosis. Complications. Complications arising from optic neuritis may include: Optic nerve … WebNov 20, 2024 · Summary Optic nerve hypoplasia (ONH) is a congenital disorder characterized by underdevelopment (hypoplasia) of the optic nerves. The optic nerves transmit impulses from the nerve-rich membranes lining the retina of the eye to the brain.

WebLeber Hereditary Optic Neuropathy (LHON) is the most common inherited mitochondrial disorder and typically affects young males. It typically begins as a unilateral progressive optic neuropathy with sequential involvement of the fellow eye months to years later. Treatment options are limited, but include the use of antioxidant supplements.

Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control … See more In 1979, Francis Crick suggested that controlling all cells of one type in the brain, while leaving the others more or less unaltered, is a real challenge for neuroscience. Francis Crick speculated that a technology using … See more Optogenetics provides millisecond-scale temporal precision which allows the experimenter to keep pace with fast biological information processing (for example, in probing the causal role of specific action potential patterns in defined neurons). Indeed, to … See more Selective expression One of the main problems of optogenetics is that not all the cells in question may express the microbial opsin gene at the same level. Thus, even illumination with a defined light intensity will have variable effects on individual … See more • Appasani K (2024). Optogenetics: from neuronal function to mapping and disease biology.

See more The technique of using optogenetics is flexible and adaptable to the experimenter's needs. Cation-selective channelrhodopsins (e.g. ChR2) are used to excite neurons, anion-conducting channelrhodopsins (e.g. GtACR2) inhibit neuronal activity. … See more The field of optogenetics has furthered the fundamental scientific understanding of how specific cell types contribute to the function of biological tissues such as neural circuits in … See more WebSepto-optic dysplasia (SOD), known also as de Morsier syndrome, is a rare congenital malformation syndrome that features a combination of the underdevelopment of the optic nerve, ...
