In decades of studying how neural circuits in the brain’s visual cortex adapt to experience, MIT Professor Mark Bear’s lab has followed the science wherever it has led. The journey yielded the discovery of cellular mechanisms serving visual recognition memory, in which the brain learns what sights are familiar so it can focus on what’s… Read more

Researchers at the Salk Institute report the discovery of three cell types in the eye that detect light and align the brain’s circadian rhythm to our ambient light. The study[1] marks the first direct assessment in humans of light responses from these cells, called intrinsically photosensitive retinal ganglion cells (ipRGCs), and the implications for health… Read more

An active plant-based substance that has been known for 30 years could unexpectedly turn into a ray of hope against eye tumors. The coralberry decorates many German living rooms during the winter months. At this time it forms bright red fruits, which make it a popular ornamental plant. The plant, originally from Korea, is surprisingly… Read more

A study from researchers at Indiana University has found that a major chemical component in marijuana appears to worsen the primary underpinning of glaucoma: a rise in pressure inside the eye. Treatment of glaucoma is among the most commonly proposed uses of medical marijuana. The chemical that causes this rise in pressure is cannabidiol, or… Read more

Thinning of the retina, the lining of nerve cells in the back of the eye, is linked to the loss of brain cells that produce dopamine, a new study has found. “Our study is the first to show a link between the thinning of the retina and a known sign of the progression of the… Read more
