Functional organization of the human hippocampus: insights from high-resolution functional magnetic resonance imaging.

对于基础和临床神经科学来说，理解记忆是如何在人脑中维持和存储的仍然是一个关键挑战。海马体参与情景记忆已被广泛接受。海马体的损伤会导致广泛的记忆障碍，包括所有的形式，并跨越多个领域。在人类，海马体沿着前后轴被细分为子区域：海马头、海马体和海马尾。除大型解剖亚区外，海马体是一种异质结构，可进一步划分为几个组织学定义的亚区，包括腺角、齿状回和下丘。

Understanding how memories are maintained and stored in the human brain remains a key challenge for both basic and clinical neuroscience. The involvement of the hippocampus in episodic memory is well accepted. Damage to the hippocampus results in broad memory impairment that includes all modalities and extends across multiple domains. In humans, the hippocampus is subdivided along the anteroposterior axis into subregions: the hippocampal head, body, and tail. Apart from large-scale anatomical subregions, the hippocampus is a heterogeneous structure that can be further delineated into several histologically-defined subfields, including the cornu ammonis, dentate gyrus, and subiculum.
