Immune system can slow degenerative eye disease: Mouse study
Study reveals C3, which can cause damage in some eye diseases, may help to slow the progression of retinitis pigmentosa.... Read More...
A brain region for Pokémon characters?
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...
Multitasking with perfection: Nerve cell works like 1400 individual cells – Fly Study
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...
Microglia, immune cells of the central nervous system, shown to regulate neuroinflammation
In uveitis, microglia facilitates the entry of inflammatory immune cells into the retina, enabling the host immune responses to attack cells not normally recognized by the immune system.... Read More...
How the Brain Processes Images
Researchers report signals from the retina are subjected to selective processing at the earliest neural way-station in the functional pathway connecting the retina to the visual cortex.... Read More...
Heavy Smoking Can Damage Vision
A new study reports those who smoke 20 or more cigarettes a day have a reduced ability to discriminate contrast and colors compared to non smokers. ... Read More...
Tiny Eye Movements Affect How We See Contrast
Contrast sensitivity may be a result of small eye movements people may not be aware they are making, a new study reports.... Read More...
Surprise Discovery Reveals Second Visual System in Cerebral Cortex: Mouse Study
A new study challenges 75 year old dogma of mammalian vision. Researchers have shows the post rhinal cortex obtains visual data from the superior colliculus and is not dependent upon information from primary visual cortex. ... Read More...
Neural Code that Predicts Behavior Identified
Differences in activity between the left and right superior colliculi help researchers predict whether an animal was seeing an event. ... Read More...
