Scientists from The University of Manchester have found a way to trick the eye into thinking the world is brighter than it actually is.
Using a chemical compound, the team activated a small group of retinal neurons in dim light, which unexpectedly made almost the whole retina more active.
Though more research is needed, the study provides new insight into how the retina communicates with the brain when animals respond to different situations.
The retina is a thin layer of tissue that lines the back of the eye which receives light focused by the lens, and convert it into neural signals which are sent to the brain.
The manipulation, carried out in mice, effectively increased the “bandwidth” of communication from the retina to the brain.
