A natural inbuilt timer, the circadian rhythm is a 24-hour cycle in all humans, plants, and animals determining sleep and feeding patterns. Circadian rhythms are endogenously generated and can be … Continue Reading The skin keeps time independently of the brain.
Organ donation is where a live or deceased person consents to having one or more of their organs removed and transplanted to another person. Unfortunately, there’s currently an organ shortage … Continue Reading Synthetic biology used to develop cornea capable of self-assembly.
Alzheimer’s disease (AD) is a fatal neurodegenerative disorder as well as the leading cause of senile dementia worldwide, with no effective treatment and limited functionality for early diagnosis. Now, a … Continue Reading Noninvasive eye scan can detect key signs of Alzheimer’s Disease in humans.
The purpose of blinks is to keep the eyes hydrated and to protect them. Blinks are rarely noticed by the subject as blink-induced alterations of visual input are blanked out … Continue Reading Researchers identify a new eye movement in human studies.
Biomimicry or biomimetics is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies. The goal is to create products and processes … Continue Reading New biomimetic nanoparticle successfully treats eye cancer in animal model.
In the United States alone, moderate and severe dry eye disease afflicts nearly 5 million individuals over age 65, and many more suffer from less-severe cases. Dry eye symptoms range … Continue Reading Neural stimulation for dry eye enters FDA clinical trial phase.
Autoimmune uveitis, which accounts for up to 15% of severe visual handicap in the Western world, affects the working-age population and significantly affects public health. Patients often have detectable immune … Continue Reading Study reveals how T-cells traverse blood-retinal barrier in eye disease.
Individuals with schizophrenia have trouble with social interactions and in recognizing what is real. Past research has suggested that, in schizophrenia, abnormalities in the way the brain processes visual information … Continue Reading Extensive lit. review links retinal changes to brain pathology in schizophrenia.
Glaucoma is the leading cause of irreversible blindness worldwide and a growing public health concern because of an aging global population. It is often associated with increased fluid pressure in … Continue Reading Large-scale study finds link between blood levels of metals and glaucoma.
The retina is a layer of tissue in the back of the eye that converts light into nerve impulses. The retina contains small, specialized neurons called bipolar cells that transmit … Continue Reading Researchers discover previously uncharted part of the eye.
Researchers successfully implant and control light-sensitive opioid receptors in mice via optogenetics.
Despite the abuse potential of opioid drugs, they have long been the best option for patients suffering from severe pain. The drugs interact with receptors on brain cells to tamp … Continue Reading Researchers successfully implant and control light-sensitive opioid receptors in mice via optogenetics.
A new study from scientists at The Scripps Research Institute (TSRI) shows that nerve cells and blood vessels in the eye constantly talk to each other to maintain healthy blood … Continue Reading Study finds nerve cells and blood vessels in eye ‘talk’ to prevent disease.
Once-a-week nanoparticle injection successfully prevents corneal transplant rejection in animal study.
There are about 48,000 corneal transplants done each year in the U.S., compared to approximately 16,000 kidney transplants and 2,100 heart transplants. Out of the 48,000 corneal transplants done, 10 … Continue Reading Once-a-week nanoparticle injection successfully prevents corneal transplant rejection in animal study.
Researchers at Massachusetts General Hospital (MGH) and Massachusetts Institute of Technology (MIT) have added another piece to the complex puzzle of how the brain controls one of the most essential … Continue Reading Optogenetics study identifies neurons important for induction of natural REM sleep.
New technology advances eye tracking as biomarker for brain function and recovery from brain injury.
Researchers at NYU Langone Medical Center and the Steven & Alexandra Cohen Veterans Center have developed new technology that can assess the location and impact of a brain injury merely … Continue Reading New technology advances eye tracking as biomarker for brain function and recovery from brain injury.
