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”).

More than Meets the Eye

A new study led by researchers at Harvard Medical School and the VA Boston Healthcare System shows that face blindness may arise from deficits beyond visual perception and appears to involve glitches in retrieving various contextual cues from memory.

Researchers uncover a critical early step of the visual process

The key components of electrical connections between light receptors in the eye and the impact of these connections on the early steps of visual signal processing have been identified for the first time.

Scientists Discover a New Connection Between the Eyes and Touch

Tiny eye movements can be used as an index of humans’ ability to anticipate relevant information in the environment independent of the information’s sensory modality.

Star-Shaped Brain Cells May Play a Critical Role in Glaucoma

After a brain injury, cells that normally nourish nerves may actually kill them instead, a new NYU study in rodents finds. This “reactive” phenomenon may be the driving factor behind neurodegenerative diseases like glaucoma, a leading cause of blindness.

Researchers look to the eye for insights about the brain

Researchers seeking to unravel the mysteries of how our amazingly complex brains do what they do, often start with the eye. The retina, the light-sensing tissue at the back of the eye has long been a model for scientists to explore how the brain works.

Inhibitory Interneurons in Hippocampus Excite the Developing Brain

A new study from the George Washington University finds that in some parts of the developing brain, the inhibitory neurons cause excitation rather than suppression of brain activity, which could have implications for the treatment of neonatal seizures.

Faces, bodies, spiders, and radios: How the brain represents visual objects

Caltech researchers have combined tools from machine learning and neuroscience to discover that the brain uses a mathematical system to organize visual objects according to their principal components. The work was published June 3 in Nature.

'Time is vision' after a stroke

A person who has a stroke that causes vision loss is often told there is nothing they can do to improve or regain the vision they have lost. But research from the University of Rochester may offer hope to stroke patients in regaining vision.

Early visual experience drives precise alignment of cortical networks critical for binocular vision

Researchers at the Max Planck Florida Institute for Neuroscience identify three distinct cortical representations that develop independent of visual experience but undergo experience-dependent reshaping, an essential part of cortical network maturation.
