SO ASK YOURSELF WHY ? .... YOU WANT TO THINK IT IS ONLY SCIFI ... WHEN IT IS REALLY THE AI...AND THE EYE IN THE SKY. Neurons interact via electrical signals known as action potentials, and modulating the electrophysiology of targeted neurons is a key to understanding the brain on a cellular level. Most current methods require genetic modifications to make cells sensitive to light so they can be optically controlled or are imprecise and require high energies that can damage cells. Writing in PNAS, Sahil Rastogi and colleagues present a remote, non-genetic method to optically modulate neuronal activity by using nanowires of ‘fuzzy graphene’ to make precise contact with brain cells. https://www.nature.com/articles/s42254-020-0202-8
