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.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Our thirst for novelty begins in the eye itself

Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection operates in many visual environments.

Scientists develop a way to block the signals responsible for neuropathic pain

Remember how it felt the last time you burned your finger on a hot stove? Imagine what it's like to have that burning pain in your hands or feet all the time and know there's virtually nothing you can do about it.

Retina and its circuits are much more pliable than scientists previously thought

A new Oregon Health & Science University study is opening scientists' eyes to the retina's ability to rewire itself so it can adapt to different levels of ambient light.

Bionic eyes from Stanford

Stanford physicists and eye doctors have teamed up to design a "bionic eye," of sorts. On Feb. 22 in the Journal of Neural Engineering, Daniel Palanker, Alexander Vankov and Phil Huie from the Department of Ophthalmology and the Hansen Experimental Physics Laboratory and Stephen Baccus from the Department of Neurobiology published a design of an optoelectronic retinal prosthesis system that can stimulate the retina with resolution corresponding to a visual acuity of 20/80

High-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked development of glaucoma

In a discovery that could point to new treatments for a wide range of neurodegenerative diseases, Jackson Laboratory researchers have found that high-dose radiation and bone marrow transfer treatments on glaucoma-susceptible mice completely blocked the development of glaucoma, by preventing neurodegeneration.

Melanopsin plays a key role in the inner workings of the eye

A Brown University team has found that a protein called melanopsin plays a key role in the inner workings of mysterious, spidery cells in the eye called intrinsically photosensitive retinal ganglion cells, or ipRGCs.

Scientists have given blind nerve cells the ability to detect light

Scientists at the University of California, Berkeley, have given "blind" nerve cells the ability to detect light, paving the way for an innovative therapy that could restore sight to those who have lost it through disease.

Neurologists have discovered a drug application smart enough to alleviate orthostatic hypotension

Mayo Clinic neurologists have discovered a drug application smart enough to alleviate orthostatic hypotension -- problems with sinking blood pressure when standing up from a sitting position -- without the unwanted effect of also causing patients' blood pressure to soar when lying down.
