Understanding the minutiae of seeing in 3D

So much has to go right as our visual systems develop. One of them is that many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye's optic nerve via delicate projections, or axons, to precise ...

Inner ear stem cells hold promise for restoring hearing

Spiral ganglion cells are essential for hearing and their irreversible degeneration in the inner ear is common in most types of hearing loss. Adult spiral ganglion cells are not able to regenerate. However, new evidence in ...

The end of a dogma: Bipolar cells generate action potentials

To make information transmission to the brain reliable, the retina first has to "digitize" the image. Until now, it was widely believed that this step takes place in the retinal ganglion cells, the output neurons of the retina. ...

Toward a computer model that predicts the outcome of eye diseases

The eye hosts a powerful biological computer, the retina. Understanding how the retina transforms images from the outside world into signals that the brain can interpret would not only result in insights into brain computations, ...

Research maze puts images on floor, where rodents look

A rodent in a maze is a staple—even a stereotype—of experimental psychology research. But the maze in the lab of Rebecca Burwell, professor of cognitive, linguistic, and psychological sciences at Brown University, is ...

Photopharmacology: Optoswitches turn pain off and sight on

Photoreactive compounds developed by scientists of Ludwig-Maximilians-Universitaet (LMU) in Munich directly modulate nerve-cell function, and open new routes to the treatment of neurological diseases, including chronic pain ...

Shedding light on the synaptic complexities of vision

An individual retinal cell can output more than one unique signal, according to a Northwestern Medicine study published in Nature Communications, a finding that sheds new light on the complexities of how vision functions ...
