How does the anterior mid-cingulate cortex work?

The anterior mid-cingulate cortex (aMCC) is a highly connected hub that helps allocate energy and other resources according to your goals and the challenge at hand, supporting tenacity and willpower. It receives and sends signals linked to autonomic function, reward, bodily state, context, and action. 1 2

1. Activity rises during difficult tasks: The aMCC is more active during hard than easy tasks, and greater activity is associated with persistence, grit, and willingness to exert effort. 3 4

2. Reduced activity, depression, apathy, and resisting temptation: Disruptions to aMCC function are associated with greater apathy and depression and less tenacity. Successful dieters show higher activity, especially when resisting tempting food; people who struggle to meet weight-loss goals show lower activity. 5 6

3. Challenging experiences can strengthen its connections: The aMCC has a capacity for synaptic plasticity—connections can strengthen or new ones can form. Engaging in safe, difficult activities, including doing things you would rather avoid or resisting an impulse, can build this capacity, with potential carryover to other challenges. 7

4. Super-agers and maintaining function: Super-agers tend to retain a larger aMCC than age-matched peers, alongside healthy cognition. Regularly taking on safe cognitive or physical challenges may help maintain or build aMCC function, though the association with super-aging is described as a correlation. 8 9
