有人提出，海马体选择性地支持检索上下文关联，但另一种观点认为，海马体支持强记忆，无论它们是否包含上下文信息。我们采用了一种记忆测试，结合了“记住/知道”和源记忆程序，并允许测试项目被隔离的记忆强度（识别准确性），并分别由上下文信息的质量，可以检索（索引的准确性/信心的源记忆判断）。通过功能磁共振成像测量，与检索相关的海马活动跟踪检索到的上下文信息的质量，而不是记忆强度。这些发现与海马支持背景回忆而不是更普遍的识别记忆的提议是一致的。
It has been proposed that the hippocampus selectively supports retrieval of contextual associations, but an alternative view holds that the hippocampus supports strong memories regardless of whether they contain contextual information. We employed a memory test that combined the ‘Remember/Know’ and source memory procedures, and that allowed test items to be segregated both by memory strength (recognition accuracy) and, separately, by the quality of the contextual information that could be retrieved (indexed by the accuracy/confidence of a source memory judgment). As measured by fMRI, retrieval-related hippocampal activity tracked the quality of retrieved contextual information and not memory strength. These findings are consistent with the proposal that the hippocampus supports contextual recollection rather than recognition memory more generally.
