肥胖症在临床上是通过一个简单的公式诊断的,这个公式是基于一个人的体重和身高(身体质量指数),但它与一系列其他行为症状有关,这些症状可能是神经学上的。近年来,许多科学家都在研究药物成瘾和肥胖是否会发生类似的行为和认知变化,这让许多人开始讨论“食物成瘾”的可能性。对摄食行为和药物成瘾背后的回路的理解的进展可能使我们能够从神经回路的角度来考虑这个问题,以补充行为的观点。在这里,我们回顾了对这些回路的理解的进展,并利用它们来考虑与药物成瘾进行比较是否有助于理解某些形式的肥胖。
Obesity is clinically diagnosed by a simple formula based on the weight and height of a person (body mass index), but is associated with a host of other behavioral symptoms that are likely neurological in origin. In recent years, many scientists have asked whether similar behavioral and cognitive changes occur in drug addiction and obesity, lending many to discuss the potential for “food addiction”. Advances in understanding the circuitry underlying both feeding behaviors and drug addiction may allow us to consider this question from the viewpoint of neural circuits, to complement behavioral perspectives. Here, we review advances in understanding of these circuits and use them to consider whether drawing comparisons to drug addiction is helpful for understanding certain forms of obesity.
