Scientists have created a method that allows them to insert fictitious memories into mice, though the method can probably work in other brains, too. Neural science has frequently used chemicals or electricity to stimulate and explore the brain’s functions. This new method, optogenetics, uses viruses to alter neurons so they are sensitive to light; then light is used to affect those neurons. Optogenetics is more precise and more responsive than previous methods. The method also made it possible for the researchers to implant memories of events that never happened, suggesting avenues for research but also new treatments for mental disorders – particularly disorders that involve memory that are also resistant to drugs.
