A new, lasting consequence of COVID-19 infection has been identified. Researchers report they have identified significant abnormalities in the eyes of those with severe coronavirus infection. Read More
Routine eye exams could help identify changes associated with cognitive decline in patients with type 1 diabetes. Read More
The topmost layer of neurons in the retina of mouse models of Alzheimer's disease exhibits textural changes. The findings could be a new biomarker for Alzheimer's disease. Read More
A new study puts into question conventional belief that the eyes communicate with the brain exclusively via one signaling pathway. Researchers have identified a subset of retinal neurons that sends inhibitory signals to the brain. This subset of neurons is also involved in the synchronization of circadian rhythms to light/dark cycles and pupil constriction to bright light intensity. Read More
Light sensitive cells in the fetal retina communicate as part of an interconnected network, giving the retina more light sensitivity during development that previously believed. Read More
Fruit flies exposed to blue light had significantly reduced longevity than those exposed to natural light or kept in darkness. Exposure to blue light for 12 hours a day accelerated aging phenotypes, causing retinal damage, neurodegeneration, and impaired locomotion. Read More
Noradrenaline is essential for astrocytes to respond to local stimulation. Read More
Using optogenetics, researchers stimulated neurons in the visual cortex of mice to induce illusory images in the animals' minds. Read More
Gene therapy can restore the structure of the retina and regain normal light responses. Read More
Study reveals C3, which can cause damage in some eye diseases, may help to slow the progression of retinitis pigmentosa. Read More
Adults who played Pokemon video games as children had preferential activation in the visual system for Pokemon character, researchers report. The finding shed light on the development of the visual system and categorization in the brain. Read More
CT1 cells connect around 1400 areas in the fly brain. Each cell area works like a separate neuron, allowing CT1 to access information from the fly's eye and support local motion detection. Read More
