Retina ‘hardwired’ to predict path of moving objects

August 2, 2021

Neural circuits in the primate retina can generate the information needed to predict the path of a moving object before visual signals even leave the eye, UW Medicine researchers demonstrate in a new paper.

Cell-replacement Therapies for Visual System Disorders

July 30, 2021

Two translational studies at the Vanderbilt Eye Institute are targeting photoreceptors and retinal ganglion cells (RGCs) to restore vision through regeneration of the retina. The research is funded by the NEI Audacious Goals Initiative.

Scientists uncover how decisions about what we see are relayed back through the brain

July 27, 2021

Researchers at the National Institutes of Health have discovered that decisions based on visual information is broadcast widely to neurons in the visual system, including to those that are not being used to make the decision.

Brain’s ‘memory center’ needed to recognize image sequences but not single sights

July 26, 2021

A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus.

Scientists discover gene therapy provides neuroprotection to prevent glaucoma vision loss

July 22, 2021

A form of gene therapy protects optic nerve cells and preserves vision in mouse models of glaucoma, according to research supported by NIH’s National Eye Institute. The findings suggest a way forward for developing neuroprotective therapies for glaucoma.

How neurons get past "no"

June 24, 2021

When looking at a complex landscape, the eye needs to focus in on important details without losing the big picture. Now, a new study by Salk scientists shows how inhibitory neurons play a critical role in this process.z

NIH-funded study shows children recycle brain regions when acquiring new skills

June 17, 2021

Scientists studied the brain activity of school-aged children during development and found that regions that activated upon seeing limbs (hands, legs, etc.) subsequently activated upon seeing faces or words when the children grew older.

Scientists unravel the function of a sight-saving growth factor

June 16, 2021

Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye.

What makes us sneeze?

June 15, 2021

A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex.

As novel sights become familiar, different brain rhythms, neurons take over

June 9, 2021

A new study by researchers at MIT’s Picower Institute for Learning and Memory substantially advances understanding of how a mammalian brain enables “visual recognition memory.”
