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...
Combining Technologies to View the Retina in Unprecedented Detail
Researchers say adaptive optics enables direct imaging of neural tissue, which could lead to earlier detection of diseases that affect eye tissue.... Read More...
Mini Retinas Shed Light on Connection Between Eyes and Brain
Findings could help to develop new treatments to restore site when connections between the eyes and brain are damaged, researchers say.... Read More...
Dish Grown Human Retinas Explain How Color Vision Develops
Using human retinal tissue grown from stem cells, researchers shed light on how color vision develops. The study found thyroid hormones dictated whether the cells became blue, green or red photoreceptors.... Read More...
Category Learning Can Be Influenced By Where an Object is in Our Field of Vision
Where objects appear in a person's visual field can affect the ability to determine what the object is, researchers say.... Read More...
Visualizing the Connections Between Eye and Brain
A new study describes the activity of retinal neurons as they deliver visual information to the thalamus, an area of the brain implicated in image processing.... Read More...
Why the Eyes Could be the Window to Neurodegenerative Diseases, Like Alzheimer’s
Researchers say a new retinal imaging test could be a reliable tool for measuring the progression of neurodegenerative diseases, such as Alzheimer's. The study reports the tool can detect drusen, which is often higher in those with AD.... Read More...
