研究表明，背外侧前额叶皮质(DLPFC)对于追求目标具有重要意义，DLPFC的不同区域与接近和回避动机有关。考虑到目标追求过程的复杂性，DLPFC很可能是包括眶前皮质(OFC)、扣带回、杏仁核和基底节的网络的一部分。这一假设在目标追求的一个组成部分上得到了验证，即在分心的情况下保持目标。对DLPFC动机相关区域连通性的研究支持网络假说。不同的连通性模式表明DLPFC区域具有不同的作用，一个参与选择接近目标，一个参与选择回避目标，一个参与选择目标追逐策略。最后，特质动机的差异调节了DLPFC和OFC之间的连通性，这表明这种连通性对于实例化动机是重要的。
Research indicates that dorsolateral prefrontal cortex (DLPFC) is important for pursuing goals, and areas of DLPFC are differentially involved in approach and avoidance motivation. Given the complexity of the processes involved in goal pursuit, DLPFC is likely part of a network that includes orbitofrontal cortex (OFC), cingulate, amygdala, and basal ganglia. This hypothesis was tested with regard to one component of goal pursuit, the maintenance of goals in the face of distraction. Examination of connectivity with motivation-related areas of DLPFC supported the network hypothesis. Differential patterns of connectivity suggest a distinct role for DLPFC areas, with one involved in selecting approach goals, one in selecting avoidance goals, and one in selecting goal pursuit strategies. Finally, differences in trait motivation moderated connectivity between DLPFC and OFC, suggesting that this connectivity is important for instantiating motivation.
