Within the hippocampus - a curved elongated ridge located in each of the brain's two temporal lobes - is a structure called the dentate gyrus, which produces new neurons throughout adult life. Chronic stress inhibits neurogenesis and also causes many hippocampal neurons to shrink - a process called "remodeling."
海马是大脑两个颞叶上细长弯曲的凸起。海马内有一个叫做齿状回的组织，在整个成人时期产生新的神经元。慢性压力会抑制神经元的生成，同时致使许多海马神经元收缩--这个过程被称为"再塑"。动物研究显示，应激荷尔蒙血浆皮质醇、以及大脑中的神经传递素在神经元的再塑中也发挥着重要作用。
