The prefrontal cortex: holding the goal
The prefrontal cortex, at the front of the brain, keeps goals and rules active while you act, and biases the rest of the brain toward what's relevant. It's how you remember what you walked into a room for. Established
The anterior cingulate: noticing the drift
The anterior cingulate cortex (ACC) sits on the inner surface of each hemisphere, curving around the band that connects them. It is active when there is conflict between what you intended and what you're doing, including the moment you realise your mind has wandered. Established
That noticing is the rep. Meditation research describes "wander, notice, return" as the basic exercise of attention training. Emerging
Implementation intentions
Pairing a goal with a concrete "when X happens, I will do Y" plan roughly doubles follow-through compared with the goal alone, across nearly a hundred studies. This is one of the most robust findings in goal psychology, and it's the reason your sessions rehearse one small, specific action rather than an abstract outcome. Established
