虽然海马体长期以来被认为是记忆不可或缺的结构，但形态与功能之间的关系尚未得到充分解释。我们对海马齿状突起进行了分析，这是一种以前从未探索过的与情景记忆关系的形态特征。在这种情况下，“海马齿状”是指表面卷曲，主要存在于海马体下部的 CA1/下托中。使用超高分辨率结构 MRI 可视化海马齿状，并使用新型视觉评级量表进行评估。研究发现，在 22 名健康成年人的样本中，海马齿状突起的程度在个体之间存在很大差异，并且与言语记忆回忆和视觉记忆识别呈正相关。这项研究首次描述了健康人群中海马齿状结构的变化，并证明了其与情景记忆方面的关联。
While the hippocampus has long been identified as a structure integral to memory, the relationship between morphology and function has yet to be fully explained. We present an analysis of hippocampal dentation, a morphological feature previously unexplored in regard to its relationship with episodic memory. “Hippocampal dentation” in this case refers to surface convolutions, primarily present in the CA1/subiculum on the inferior aspect of the hippocampus. Hippocampal dentation was visualized using ultra-high resolution structural MRI and evaluated using a novel visual rating scale. The degree of hippocampal dentation was found to vary considerably across individuals, and was positively associated with verbal memory recall and visual memory recognition in a sample of 22 healthy adults. This study is the first to characterize the variation in hippocampal dentation in a healthy cohort and to demonstrate its association with aspects of episodic memory.
