Using a flash of light, scientists have inactivated and then reactivated a memory in genetically engineered rats. The study is the first cause-and-effect evidence that strengthened connections between neurons are the stuff of memory. The findings add to mounting evidence that the brain represents a memory by forming assemblies of neurons with strengthened connections, or synapses.

SAN DIEGO, June 2, 2014 — A new optogenetics technique could essentially control memories, showing potential for treating brain-related conditions such as Alzheimer’s disease.
A team from the University of California, San Diego, has discovered how to use optogenetics techniques to deactivate and then reactivate memories in the brains of genetically engineered rats. This is the first evidence demonstrating that this can be done by stimulating nerves in the brain via synapsis.
“We can form a memory, erase that memory and we can reactivate it at will by applying a stimulus that selectively strengthens or weakens synaptic connections,” said Dr. Roberto Malinow, professor of neurosciences at UCSD.
