Neuroimaging and lesion studies have seemed to converge on the idea that the hippocampus selectively supports recollection. However, these studies usually involve a comparison between strong recollection-based memories and weak familiarity-based memories. Studies that avoid confounding memory strength with recollection and familiarity almost always find that the hippocampus supports both recollection and familiarity. We argue that the functional organization of the medial temporal lobe (MTL) is unlikely to be illuminated by the psychological distinction between recollection and familiarity and will be better informed by findings from neuroanatomy and neurophysiology. These findings indicate that the different structures of the MTL process different attributes of experience. By representing the widest array of attributes, the hippocampus supports recollection-based and familiarity-based memory of multiattribute stimuli.
神经影像学和损伤研究似乎都表明海马体选择性地支持回忆。然而，这些研究通常涉及对基于强烈回忆的记忆和基于微弱熟悉度的记忆之间的比较。那些避免将记忆强度与回忆和熟悉度混淆的研究几乎总是发现海马体支持回忆和熟悉度。我们认为，内侧颞叶（MTL）的功能组织不太可能通过回忆和熟悉度之间的心理学区别来阐明，而神经解剖学和神经生理学的发现将提供更好的信息。这些发现表明，MTL 的不同结构处理不同的经验属性。通过表示最广泛的属性集，海马体支持基于回忆和基于熟悉度的多属性刺激的记忆。
