Ganglion News and Research

RSS

In anatomy, a ganglion (plural ''ganglia'') is a biological tissue mass, most commonly a mass of nerve cell bodies. Cells found in a ganglion are called ganglion cells, though this term is also sometimes used to refer specifically to retinal ganglion cells.

Gene variant discovery could lead to future glaucoma treatments

An international team, led by researchers from the University of California, San Diego School of Medicine and the National Eye Institute, has discovered gene variants for glaucoma in a black population. The finding could lead to future treatments or a cure for this disease, which leads to blindness in two million Americans each year.

FDA approves Sirion's Zirgan for treating acute herpetic keratitis

Sirion Therapeutics, Inc., a privately held ophthalmic-focused biopharmaceutical company, announced today that the US Food and Drug Administration (FDA) has approved its New Drug Application for Zirgan(TM) (ganciclovir ophthalmic gel) 0.15% as a treatment for acute herpetic keratitis (dendritic ulcers). The FDA granted orphan drug designation to Zirgan for this indication in April 2007.

MRF announces winners of six 2009 research grants

The Migraine Research Foundation (MRF), the only nonprofit organization devoted solely to funding migraine research, today announced the winners of the 2009 research grants. This year's grantees will explore such important areas as pediatric migraine, the genetic association between migraine and cardiovascular events, and why opioids enhance migraine pain.

Growth factor TGF-beta helps maintain health of retinal blood vessels

Scientists at Schepens Eye Research Institute have found that the growth factor known as TGF-beta is essential to the health of blood vessels in the retina and that blocking it can cause retinal dysfunction.

How the retina works: Like a multi-layered jigsaw puzzle of receptive fields

About 1.25 million neurons in the retina -- each of which views the world only through a small jagged window called a receptive field -- collectively form the seamless picture we rely on to navigate our environment.

Experts discuss factors that may contribute to glaucoma

Although scientists know progressive degeneration of retinal ganglion cells and their axons is the primary cause of glaucoma, researchers have yet to identify a way to stop or prevent the degeneration.

Evidence of retina self-repair in mammals

Researchers at the University of Washington (UW) have reported for the first time that mammals can be stimulated to regrow inner nerve cells in their damaged retinas.

New discovery may lead to new drugs to regulate sleep

A team of scientists from Oxford University in the UK have discovered the reason why people feel drowsier in dim lighting and more alert in bright white light.

Different processes govern sight, light detection

A Johns Hopkins University biologist, in research with implications for people suffering from seasonal affective disorder and insomnia, has determined that the eye uses light to reset the biological clock through a mechanism separate from the ability to see.

Real-time imaging device may improve surgery for congenital colon disease

Researchers at Cedars-Sinai Medical Center are developing a spectral imaging system that could result in shorter operating times for infants undergoing surgery for Hirschsprung's disease, according to a mouse study reported in the Journal of Biophotonics.

Research may bring new generation of cochlear implants

A Rutgers University team led by neuroscientist Robin Davis is opening new doors to improved hearing for the congenitally or profoundly deaf.

Blind humans lacking rods and cones retain normal responses to non-visual effects of light

In addition to allowing us to see, the mammalian eye also detects light for a number of "non-visual" phenomena.

Discovery of type of retinal cell that sees motion

A research team combining high-energy physicists from the University of California, Santa Cruz, and neuroscientists from the Salk Institute in La Jolla, Calif., has discovered a type of retinal cell that may help monkeys, apes, and humans see motion.

Overview of common hand conditions and treatments

When a wrist hurts, it could be carpal tunnel syndrome -- or something else. Over time, many conditions can affect crucial parts of the hands, causing everything from pain to the loss of normal function.

Nanomedicine opens the way for nerve cell regeneration

The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way.

Visual prosthesis

When the idea appeared several years ago, it sounded persuasive: How about implanting electrodes at the defective retina of blind subjects and connecting them with a mini camera in order to re-establish vision.

How much and what the eye tells the brain

Researchers at the University of Pennsylvania School of Medicine estimate that the human retina can transmit visual input at about the same rate as an Ethernet connection, one of the most common local area network systems used today.

New orthostatic hypotension treatment reduces symptoms without causing high blood pressure

A drug traditionally used to treat myasthenia gravis shows potential benefit for reducing symptoms of orthostatic hypotension without raising blood pressure when people lie down, according to results of a double-blind, controlled clinical trial.

Evidence that the eye has complementary brain-signaling systems at work

A new retinal photoreceptor adjusts its sensitivity in different lighting conditions, according to scientists at Brown University, where the rare eye cells were discovered.
