:: From eye to brain: 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 visual signals from the eye to the brain."

A unique neural recording system developed by an international team of high energy physicists, which is able to record simultaneously the tiny electrical signals generated by hundreds of the retinal output neurons, is one of the essential elements of the study. Recording electrodes are shown in the foreground and retinal ganglion cells in the background.
