Optical illusion with circles that appear to rotate

Optical illusions explained in a fly’s eyes

Why people perceive motion in some static images has mystified not only those who view these optical illusions but neuroscientists who have tried to explain the phenomenon. Now Yale neuroscientists have found some answers in the eyes of flies.

How Do We Prioritize What We See?

A new study by a team of neuroscientists has discovered that one specific region, the occipital cortex, plays a causal role in piloting our attention to manage the intake of images.

New treatment targets found for blinding retinal disease

When the eye isn’t getting enough oxygen in the face of common conditions like premature birth or diabetes, it can result in blindness. Scientists have identified new points where they may be able to enable recovery.

UW researchers devise approach to treat rare, incurable form of blindness

Scientists at the University of Wisconsin‒Madison have published a proof-of-concept method to correct an inherited form of macular degeneration that causes blindness, and that is currently untreatable.

Ultra-low power brain implants find meaningful signal in grey matter noise

University of Michigan researchers have dramatically reduced the power requirements of neural interfaces while improving their accuracy—a discovery that could lead to long-lasting brain implants.

Neurons are genetically programmed to have long lives

Researchers reveal a mechanism by which long-term survival of neurons is intrinsically programmed during development.

Study points to potential new approach to treating neurodegenerative diseases like glaucoma and Alzheimer’s disease

Researchers have shown for the first time that when one optic nerve in the eye is damaged, as in glaucoma, the opposite optic nerve comes to the rescue by sharing its metabolic energy.

Study helps to settle debate on roles of REM and non-REM sleep in visual learning

A study by a team of Brown University researchers sheds new light on the complementary roles of REM and non-REM sleep in visual perceptual learning.

Combating drug resistance in age-related macular degeneration

Researchers have discovered a strategy that can potentially address a major challenge to the current treatment for choroidal neovascularization (CNV), an aggressive form of age-related macular degeneration.

Study finds that special filters in glasses can help the color blind see colors better

A new study found that special patented glasses engineered with technically advanced spectral notch filters enhance color vision for those with the most common types of red-green color vision deficiency (“anomalous trichromacy”).
