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...

A paper published online on January 10 in the Journal of Experimental Medicine reports that retinal ganglion cells"”neurons in the eye"”are rescued by immune cells that infiltrate the mouse retina after eye injury. A group led by Michal Schwartz at the Weizmann Institute detected immune cells called macrophages in the retinas of mice that sustained eye injuries a few days prior. Thanks to their expression of an anti-inflammatory protein, these macrophages dampened injury-induced...

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...

CAMBRIDGE, Mass., July 7, 2005 -- 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. "Apparently our thirst for novelty begins in the eye itself," says Markus...
