> Both behavioral extremes, however, result from a failure in self-regulation. And neuroscience now strongly suggests that such dysregulation plays a key role in addiction. In fact, similar brain circuits are involved in both addiction and obsessive-compulsive disorder (OCD): whether the problem is failing to stop an impulsive action or failing to end a habitual routine, many of the same regions are engaged. It is here that addiction is learned.
