Switching off a specific brain region can alter ingrained habits in rats.

Ingrained habits in rats can be quickly broken—and reestablished—by targeting and switching off a specific site in the brain’s prefrontal cortex using a technique known as optogenetics, according to an NIMH-funded study published November 13, 2012, in the Proceedings of the National Academy of Sciences (PNAS).
