Researchers explained that millions of people around the world experience vision loss due to
To help them, technology has already appeared thatmakes their life better. "Argus II", the world's first retinal prosthesis, reproduces some functions of the organ - patients with it can perceive the outlines of objects and objects, this allows them to safely move along the street.
Now researchers from the University of SouthCalifornia (USC) tried to improve this technology by using an advanced computer model of what happens in the retina. Their experimentally validated model reproduces the shapes and positions of millions of nerve cells, as well as the physical and network properties associated with them.
The network of nerves between the eyes and the brain arose 100 million years earlier than thought
By focusing on models of nerve cells,which transmit visual information from the eye to the brain, researchers have identified ways to potentially increase clarity and color vision in future retinal prostheses.
Scientists noted that photoreceptors die off in degenerative eye diseases, "Argus II" delivers signals directly to these cells.
Thus, the patient receives a tiny ophthalmicimplant with a set of electrodes. These electrodes are remotely activated when a signal is transmitted from a pair of special glasses on which the camera is mounted. The light detected by the camera determines which retinal ganglion cells are activated by the electrodes, sending a signal to the brain, resulting in a black-and-white image of 60 dots.
