The brain lowered a craving signal before the person noticed

In a small study, ten people with moderate-to-severe cannabis use disorder watched a live measure of brain activity and tried to lower it. Activity fell in the anterior cingulate cortex and several related regions, but subjective craving did not change before and after the session. This was only a feasibility test without placebo control, yet the paradox is already clear: the instrument moved before the inner narrator did.
