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

了解记忆是如何在人脑中维持和储存的，仍然是基础和临床神经科学的一个关键挑战。海马体参与情景记忆已被广泛接受。海马体损伤导致广泛的记忆障碍，包括所有模式，并延伸到多个领域。在人类中，海马体沿着前后轴被细分为亚区：海马体头部、体和尾。除了大规模的解剖亚区，海马体是一个异质结构，可以进一步划分为几个组织学定义的亚区，包括锥体、齿状回和下骨。

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.
