The lateral hypothalamic area (LHA) has two major roles: arousal/waking and food intake controls. Here, it is shown that a premammillary part of the LHA is neurochemically and cytoarchitectonically distinct from the tuberal LHA in male rats. This part contains nuclear masses, namely the parasubthalamic nucleus and the calbindin nucleus, involved in pathways that predict its participation in the control of food intake. Analyzing c-Fos expression in experiments related to feeding behavior, this region responded specifically to the ingestion of palatable nutriments.
外侧下丘脑区域（LHA）有两个主要作用：唤醒/觉醒和食物摄入控制。在此研究中发现，雄性大鼠LHA的乳头前部分在神经化学和细胞结构上与结节性LHA不同。该部分包含核团，即丘脑底旁核和钙结合蛋白核，这些核团参与的通路表明其参与食物摄入控制。在与进食行为相关的实验中分析c-Fos表达时，该区域对美味营养物质的摄入有特异性反应。
