中扣带皮层（MCC）被认为是一个大规模系统中的中心节点，致力于在不断变化的环境中调整行为。虽然MCC在连接动作和认知中的作用已经得到了很好的确立，但其在调节自主神经系统中的作用却知之甚少。然而，对新的或威胁性的情况的适应性反应会引起交感神经系统和副交感神经系统的协调变化。MCC中的躯体运动图是背腹侧组织的。对文献的荟萃分析表明，背腹组织也可能涉及与自主神经系统的连接。MCC的背侧和腹侧部分的激活分别与交感神经和副交感神经系统的募集相关。数据还表明，在MCC，对交感神经系统的预测映射沿着感觉运动系统以下相同的颈骶组织的脊髓上的骨骼运动控制的预测。
The midcingulate cortex (MCC) is viewed as a central node within a large-scale system devoted to adjusting behavior in the face of changing environments. Whereas the role of the MCC in interfacing action and cognition is well established, its role in regulating the autonomic nervous system is poorly understood. Yet, adaptive reactions to novel or threatening situations induce coordinated changes in the sympathetic and the parasympathetic systems. The somatomotor maps in the MCC are organized dorsoventrally. A meta-analysis of the literature reveals that the dorsoventral organization might also concern connections with the autonomic nervous system. Activation of the dorsal and ventral parts of the MCC correlate with recruitments of the sympathetic and the parasympathetic systems, respectively. Data also suggest that, in the MCC, projections toward the sympathetic system are mapped along the sensory-motor system following the same cervico-sacral organization as projections on the spinal cord for skeletal motor control.
