“That plasticity allows for the pruning of some neural pathways and the formation of others, enabling the brain to adapt and to learn.

“Ideally, we would need to find a molecule that blocks formation of a memory of a drug-induced high, while not interfering with the ability to remember important things.”

Her colleague, graduate student Andrea Globa, added: “Through genetic engineering, we hard-wired in place the synapses in the reward circuits of these mice.

“By preventing the synapses from strengthening, we prevented the mutant mice from ‘learning’ the memory of cocaine, and thus prevented them from becoming addicted.”

"Genome editing has become a common tool in laboratories around the world. The most common technique, called Crispr-cas9, works like a pair of molecular scissors. It is essentially a pair of enzymes that can be designed to find and remove a specific strand of DNA inside a cell, and then replace it with a new piece of genetic material. The procedure can be used to rewrite single letters of genetic code and even whole genes."
