Neural Regeneration Research Researchers at the University of Birmingham, UK, led by Dr. Ben Scheven, Dr. Wendy Leadbeater and Ben Mead have discovered that stem cells isolated from the teeth, termed dental pulp stem cells (DPSC), can protect retinal ganglion cells (RGCs) from death following injury and promote regeneration of their axons along the optic nerve. RGC loss is the leading cause of blindness and can arise through traumatic injury or degenerative diseases such as glaucoma....

Among the animals that are appealing “cover models” for scientific journals, lancelets don´t spring readily to mind. Slender, limbless, primitive blobs that look pretty much the same end to end, lancelets “are extremely boring. I wouldn´t recommend them for a home aquarium,” says Enrico Nasi, adjunct senior scientist in the MBL´s Cellular Dynamics Program. Yet Nasi and his collaborators managed to land a lancelet on the cover of The Journal of...

Working in mice, scientists at Washington University School of Medicine in St. Louis have devised a treatment that prevents the optic nerve injury that occurs in glaucoma, a neurodegenerative disease that is a leading cause of blindness. Researchers increased the resistance of optic nerve cells to damage by repeatedly exposing the mice to low levels of oxygen similar to those found at high altitudes. The stress of the intermittent low-oxygen environment induces a protective response called...

Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development. The findings reflect the expansion of developmental neurobiology and vision research at UCSB. The work is described in a recent publication of the Journal of Neuroscience. The research team examined the connectivity of nerve cells, called neurons, in mice. Neurons communicate with one another via synapses where the...

Biologists and psychologists know that light affects mood, but a new University of Virginia study indicates that light may also play a role in modulating fear and anxiety. Psychologist Brian Wiltgen and biologists Ignacio Provencio and Daniel Warthen of U.Va.'s College of Arts & Sciences worked together to combine studies of fear with research on how light affects physiology and behavior. Using mice as models, they learned that intense light enhances fear or anxiety in mice, which are...

Retinal ganglion cells can recognize directions thanks to amacrine cells The properties of optical stimuli need to be conveyed from the eye to the brain. To do this efficiently, the relevant information is extracted by pre-processing in the eye. For example, some of the so-called retinal ganglion cells, which transmit visual information to the brain via the optic nerve, only react to light stimuli moving in a particular direction. This direction selectivity is generated by inhibitory...

(Ivanhoe Newswire) -- Melanopsin, a light sensor that sets the circadian rhythm- the body's biological clock- also plays an important role in vision, according to this study.Melanopsin's messengers, called melanopsin-expressing retinal ganglion cells (mRGCs), forward information about the brightness of incoming light directly to visual centers in the brain.The results show a new role for mRGCs during image-forming vision, and suggest that these cells could make a significant contribution to...

Better known as the light sensor that sets the body's biological clock, melanopsin also plays an important role in vision: Via its messengers-so-called melanopsin-expressing retinal ganglion cells, or mRGCs-it forwards information about the brightness of incoming light directly to conventional visual centers in the brain, reports an international collaboration of scientists in this week's issue of PLoS Biology. The findings reveal a new role for mRGCs during image-forming vision and suggest...

Salk researchers map functional connections between retinal neurons at single-cell resolution By comparing a clearly defined visual input with the electrical output of the retina, researchers at the Salk Institute for Biological Studies were able to trace for the first time the neuronal circuitry that connects individual photoreceptors with retinal ganglion cells, the neurons that carry visuals signals from the eye to the brain. Their measurements, published in the Oct. 7, 2010, issue of the...
