Prediction errors play a role in the context of dynamic perceptual events that take place within fractions of a second. Findings support the hypothesis that visual perception occurs as a result of a decision process.
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.
Study highlights the risk of persistent visual side effects in men who take the highest recommended dose of viagra. Some of the visual disturbances include color vision impairments, blurred vision, and problems with light sensitivity.

Study calls into question the use of current machine learning technologies in the search for extra-terrestrial intelligent life.
The gene Elovl2 appears to play a significant role in age-associated functional and anatomical aging in mouse retinas. The finding has direct implications for age-related eye diseases, such as macular degeneration. When the expression of the gene was boosted, age-related visual function improved.

Researchers have identified a circuit in the brains of fruit flies, which enables them to see in color. The network is similar to that which allows human color vision. The findings could help in the development of AI technologies.
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.
Crashes in visual processing occur when neurons processing one image are tasked with processing another too quickly. This results in either one or both images being unable to reach our conscious awareness.
