Massachusetts Institute of Technology (MIT) Neuroscientists Identify a Brain Region That Can Switch Between New and Old Habits

Habits are behaviors wired so deeply in our brains that we perform them automatically. This allows you to follow the same route to work every day without thinking about it, liberating your brain to ponder other things, such as what to make for dinner. However, the brain's executive command center does not completely relinquish control of habitual behavior. A new study from MIT neuroscientists has found that a small region of the brain's prefrontal cortex, where most thought and planning occurs, is responsible for moment-by-moment control of which habits are switched on at a given time.
