Ganglion News and Research RSS Feed - Ganglion News and Research

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.
Researchers show how cannabinoids affect vision

Researchers show how cannabinoids affect vision

A multidisciplinary team including researchers from the Montreal Neurological Institute has improved our understanding of how cannabinoids, the active agent in marijuana, affect vision in vertebrates. [More]
Researchers identify brain circuit that helps take major developmental step despite nutritional stress

Researchers identify brain circuit that helps take major developmental step despite nutritional stress

When we go hungry, we have the ability to ignore the urge to eat such that we can carry out the task at hand. It has long been known that the brain is involved in such decisions. [More]
Researcher aims to shed new light on inner workings of the retina

Researcher aims to shed new light on inner workings of the retina

One of the more studied parts of the human anatomy, the retina -- the neural layer at the back of the eye that senses light -- still has secrets to reveal. [More]
Research offers new insights into sleep/awake patterns in animals

Research offers new insights into sleep/awake patterns in animals

Research from University of California, Irvine scientists and their colleagues offers new insights into why many animals sleep at night and are active during the day, while others do the reverse. [More]
UW Medicine researchers discover new type of neuron in mouse retina

UW Medicine researchers discover new type of neuron in mouse retina

In the retina of mice, a new type of neuron that falls outside century-old classifications has been discovered. [More]
USPTO grants key patent for Quark Pharmaceuticals' QPI-1007 ocular neuroprotectant

USPTO grants key patent for Quark Pharmaceuticals' QPI-1007 ocular neuroprotectant

Quark Pharmaceuticals, Inc. today announced that the United States Patent and Trademark Office has granted a key patent covering the treatment of patients suffering from non-arteritic anterior ischemic optic neuropathy ("NAION") with the Company's ocular neuroprotectant QPI-1007. [More]
Researchers identify how sensory nerve receptors work together to transmit itch signals

Researchers identify how sensory nerve receptors work together to transmit itch signals

Researchers have found how sensory nerve cells work together to transmit itch signals from the skin to the spinal cord, where neurons then carry those signals to the brain. Their discovery may help scientists find more effective ways to make itching stop. [More]
Study shows spinal cord stimulation can be safe, effective treatment option for chronic pain sufferers

Study shows spinal cord stimulation can be safe, effective treatment option for chronic pain sufferers

Chronic pain affects up to 20% of people in developed countries, and represents not only a profound impact on individuals and their families but also a sizeable burden on employers, health care systems, and society in general. [More]
Scientists succeed in restoring multiple key aspects of vision in mice

Scientists succeed in restoring multiple key aspects of vision in mice

Experiments conducted under the leadership of a Stanford University School of Medicine investigator have succeeded, for the first time, in restoring multiple key aspects of vision in mammals. [More]
Transorbital ACS can improve vision in patients with glaucoma, optic nerve damage

Transorbital ACS can improve vision in patients with glaucoma, optic nerve damage

Vision loss due to glaucoma or optic nerve damage is generally considered irreversible. Now a new prospective, randomized, multi-center clinical trial demonstrates significant vision improvement in partially blind patients after 10 days of noninvasive, transorbital alternating current stimulation.

Pain reliever appears to help preserve vision in animal model of retinal degeneration

Pain reliever appears to help preserve vision in animal model of retinal degeneration

A pain medicine that potently activates a receptor vital to a healthy retina appears to help preserve vision in a model of severe retinal degeneration, scientists report. [More]
Diabetic patients at risk for developing retinal diabetic neuropathy

Diabetic patients at risk for developing retinal diabetic neuropathy

A University of Iowa-led study of diabetes-related vision impairment holds good news -- and some bad news -- for patients with signs of these disorders. [More]
Newly found mechanism of color vision illustrates why people perceive color blue in dim light

Newly found mechanism of color vision illustrates why people perceive color blue in dim light

The swirling skies of Vincent Van Gogh's Starry Night illustrate a mystery that has eluded biologists for more than a century--why do we perceive the color blue in the dimly lit night sky? A newly discovered mechanism of color vision in mice might help answer this question, Caltech researchers say. [More]
IUPUI investigators use stem cells to identify potential therapies to prevent glaucoma

IUPUI investigators use stem cells to identify potential therapies to prevent glaucoma

Using stem cells derived from human skin cells, researchers led by Jason Meyer, assistant professor of biology, along with graduate student Sarah Ohlemacher of the School of Science at Indiana University-Purdue University Indianapolis, have successfully demonstrated the ability to turn stem cells into retinal ganglion cells (RGCs), the neurons that conduct visual information from the eye to the brain. [More]
NIH scientists show how neurons in the eye may use math to differentiate moving objects

NIH scientists show how neurons in the eye may use math to differentiate moving objects

Our eyes constantly send bits of information about the world around us to our brains where the information is assembled into objects we recognize. Along the way, a series of neurons in the eye uses electrical and chemical signals to relay the information. In a study of mice, National Institutes of Health scientists showed how one type of neuron may do this to distinguish moving objects. [More]
Boosting intrinsic growth programs can enhance axon regeneration of injured neurons

Boosting intrinsic growth programs can enhance axon regeneration of injured neurons

Damage to axons in the central nervous system (CNS) typically results in permanent functional deficits. Boosting intrinsic growth programs can dramatically augment the axon regeneration of injured neurons. If injured neurons can regenerate sufficient number of axons, the CNS may recover and overcome such functional deficits. [More]
Neuroprotection powers for phenytoin in acute optic neuritis

Neuroprotection powers for phenytoin in acute optic neuritis

Selective sodium channel blockade with the anti-epileptic drug phenytoin protects against acute demyelinating optic neuritis, researchers report. [More]
Interpretation of images starts in the retina

Interpretation of images starts in the retina

Tübingen researchers have shown that image processing in the eye is more extensive than previously thought. They investigated the channels that transmit information from the eye to the brain. [More]
Researchers link idiopathic congenital nystagmus to a defect in neurocomputation

Researchers link idiopathic congenital nystagmus to a defect in neurocomputation

Botond Roska and his group at the Friedrich Miescher Institute for Biomedical Research implicate a clearly defined neuron type and its circuit in the retina in the pathophysiology of idiopathic congenital nystagmus. [More]
