认知控制，即主动引导我们行为的能力，在整个青春期都在不断提高。下面，我们回顾了与年龄相关的大脑功能变化的文献，这些变化与反应抑制和工作记忆有关，支持认知控制。使用功能磁成像（fMRI）的研究结果表明，处理错误，维持认知控制状态，并达到成人水平的精度，持续到青春期。大脑功能模式的发育变化表明，认知控制电路的核心区域在发育早期就处于在线状态。然而，在整个大脑的局部过程中，以及在建立支持自上而下的行为调制的远程连接中，与年龄相关的变化可能支持更有效的神经处理，以实现最佳的成熟执行功能。虽然在了解认知发展背后的大脑过程中与年龄相关的变化方面取得了很大进展，但发育神经成像方法和数据解释仍然存在需要解决的重要挑战。
Cognitive control, the ability to voluntarily guide our behavior, continues to improve throughout adolescence. Below we review the literature on age-related changes in brain function related to response inhibition and working memory, which support cognitive control. Findings from studies using functional magnetic imaging (fMRI) indicate that processing errors, sustaining a cognitive control state, and reaching adult levels of precision, persist through adolescence. Developmental changes in patterns of brain function suggest that core regions of the circuitry underlying cognitive control are on-line early in development. However, age-related changes in localized processes across the brain and in establishing long range connections that support top-down modulation of behavior may support more effective neural processing for optimal mature executive function. While great progress has been made in understanding the age-related changes in brain processes underlying cognitive development, there are still important challenges in developmental neuroimaging methods and the interpretation of data that need to be addressed.
