How Does the Eye Work?

The human eye is a wonder of engineering. It consists of many different parts that work together to provide visual information to the brain, which then translates it into information that is useful to the body.

Timing of acetylcholine release determines if dopamine promotes movement or learning

Scientists have long-studied the role of dopamine, a chemical in the brain that helps control learning and movement, in order to better understand Parkinson's disease, schizophrenia, and depression-afflictions caused, in part, by a disruption or alteration of dopamine activity.

Study identifies early risk factors for progressive supranuclear palsy

Progressive supranuclear palsy, or PSP, is a rare brain disease that causes problems with balance, eye movements and thinking. Civil rights leader Jesse Jackson recently passed away after living with the disease for more than a decade.

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics.

New pathway explains poor response to bladder cancer immunotherapy

Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center have discovered a biological pathway that helps explain why some bladder cancers do not respond well to immunotherapy.

Lost in transmission: Changes in organ donor status can fall through cracks in the system

When Raven Kinser walked into a Virginia Department of Motor Vehicles office two summers ago, she completed a driver's license application that included the option to register as an organ donor.

Study reveals limitations of large language models in medical diagnostics

Artificial intelligence (AI) is rapidly transforming healthcare. AI systems can now detect diabetic eye disease from retinal photos and analyze CT images for signs of early-stage lung cancers and stroke.

New BrainGate iBCI typing neuroprosthesis can restore communication in patients with paralysis

Loss of communication can be among the most devastating symptoms for patients with paralysis. A new study by investigators from Mass General Brigham Neuroscience Institute and Brown University describes an investigational implantable brain computer interface (iBCI) typing neuroprosthesis that can restore communication with speed and accuracy.

Escalating Middle East conflict places severe strain on regional health systems

More than ten days into the latest escalation of conflict in the Middle East, health systems across the Region are coming under strain as injuries and displacement rise, attacks on health care continue, and public health risks increase.

Simplified nanoparticles "educate" the immune system to find and destroy disease-causing cells

Johns Hopkins Medicine scientists say they have developed a simplified version of biodegradable nanoparticles that can "educate" the immune system to find and destroy disease-causing cells throughout the body.

Severe COVID and flu infections increase risk of lung cancer

Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease's development, but vaccination heads off those harmful effects, new research from UVA Health's Beirne B. Carter Center for Immunology Research and UVA Comprehensive Cancer Center indicates.

Dual sensory loss affects confidence in navigation and sound localization

According to a recent multi-institute PLOS One study led by the Multisensory Research Lab at the Wilmer Eye Institute, Johns Hopkins Medicine, time of hearing loss onset is a key determinant of patient confidence and self-reported sound localization abilities - the ability to perceive and locate objects in an environment - even in individuals who use hearing aids or who have received vision rehabilitation training.

Photoreceptor cells can recover from early stages of cell death

Photoreceptors are specialized cells in the eye that convert light energy into neural signals.

Wegovy linked to higher risk of eye stroke and vision loss

Wegovy, a GLP-1 agonist for weight loss, may carry the highest risk of 'eye stroke' (ischemic optic neuropathy) and sudden sight loss of the semaglutide drugs, finds an analysis of unintended side effect reports published in the British Journal of Ophthalmology.

Multi-agent AI systems outperform single models under heavy clinical workloads

As artificial intelligence (AI) becomes more common in health care, from managing records to assisting with medication decisions, researchers at the Icahn School of Medicine at Mount Sinai are asking an important question: How well does AI hold up when the workload gets intense at health system scale?

Highly biocompatible corneal implants created from recycled carp scales

Serious diseases affecting the transparent part of the eye, called the cornea, are very difficult to treat because this structure lacks blood vessels and has little capacity for regeneration and repair.

Enzyme helps maintain retinal progenitor cells during eye development

The retina is a thin layer of neural tissue at the back of the eye that detects light and converts it into signals, sent to the brain.

Researchers propose that Parkinson’s disease may start in the gut, not the brain

A perspective in The Journal of Clinical Investigation argues that environmental exposures may interact with the gut microbiome and intestinal barrier to trigger biological processes linked to Parkinson’s disease. The authors propose that cumulative environmental stressors can erode host resilience, promoting α-synuclein pathology, immune activation, and neurodegeneration.

Tailoring digital safety to the child’s developmental stage

The use of generative artificial intelligence (AI), able to produce text, images and video on demand, has grown exponentially in recent years. While its applications for personal and professional use continue to expand, many have questions about how children might be interacting with this technology.
