Memory consolidation. Connections between the hippocampus and various cortical modules are critical in early memory formation (left). Over time, the cortical modules form connections among themselves and the connections with the hippocampus become less important (center). When the memory is fully consolidated, only the cortical to cortical connections are important and the hippocampus becomes unnecessary (right). Adapted with permission from Frankland PW, Bontempi B.

Retrieval of nonconsolidated and consolidated memory. A, An event with audio (A), spatial (S), and visual (V) information is encoded. The hippocampus contains a unified representation of the event and forms connections with the relevant cortical areas to process the audio, spatial, and visual information. B, When a retrieval cue containing only spatial and visual information of the event is encountered early in the memory formation process before the memory has been consolidated, the hippocampus plays a critical role by accessing its connections with the pertinent cortical areas for the entire memory. C, After the memory is fully consolidated, the connections with the hippocampus become unnecessary and the retrieval cue accesses the memory directly from the cortical to cortical network of connections that form the unified representation of the memory.

Patient H.M. and medial temporal lobe damage. A 1992 coronal T1-weighted image of patient H.M. shows abnormal hippocampal formation hypointense signal after previous bilateral medial temporal lobe resection performed decades earlier for intractable seizures. After the surgery, the patient experienced anterograde amnesia and has been extensively studied for years afterward. Adapted from Corkin S, Amaral DG, González RG, et al. H.M.'s medial temporal lobe lesion: findings from magnetic resonance imaging. J Neurosci 1997;17:3964–79.
