Artifical Synapse Powered by Light

Jul-18-19 A brain-based computer chip powered by light mimics the way the brain stores and processes information.

The artificial synapse was created by an international team to function via optogenetics, which relies on light to change the cells’ electrical activity. Connections are formed between the components using light and color to generate a photocurrent pattern, similar to the way neural connections are made by electrical impulses in the brain.

According to Sumeet Walai, lead researcher, "This technology takes us further on the path towards fast, efficient and secure light-based computing. It also brings us an important step closer to the realization of a bionic brain—a brain-on-a-chip that can learn from its environment just like humans do."
