Associative memory and the medial temporal lobes
The neural system that mediates familiarity memory
TLDR
The neural system that underlies scene familiarity memory was identified by identifying the hippocampus, and left anterior and inferolateral frontal and parietal cortices more than strong familiarity, and no brain region that was unaffected by recollection was modulated by variations in familiarity strength.
The role of recollection and familiarity in the functional differentiation of the medial temporal lobes
TLDR
There has been disagreement about whether recall/recollection is primarily mediated by the hippocampus and familiarity by the evolutionarily newer MTL cortices or whether the MTL mediates these kinds of memory in an integrated, homogeneous fashion.
Associative recognition in a patient with selective hippocampal lesions and relatively normal item recognition
TLDR
YR's familiarity memory for items, intra‐item associations, and associations between items of the same kind was mediated by her intact medial temporal lobe cortices and was preserved, whereas her hippocampally mediated recall/recollection of these kinds of information was impaired.
A disproportionate role for the fornix and mammillary bodies in recall versus recognition memory
TLDR
These findings support models of diencephalic memory mechanisms that require hippocampal inputs for recall, but not for key elements of recognition, as the volumes of the left fornix and the left mammillary bodies decreased, the difference between recall and recognition scores increased.
Recognition Memory Strength is Predicted by Pupillary Responses at Encoding While Fixation Patterns Distinguish Recollection from Familiarity
TLDR
It is found that both pupil response and fixation patterns at encoding predict later recognition memory strength, and the extent of pupillary response accompanying incidental encoding was found to be predictive of subsequent memory.
Memory for single items, word pairs, and temporal order of different kinds in a patient with selective hippocampal lesions
TLDR
Not only was word pair recognition intact in the patient, but further evidence indicates that her recognition of other associations between items of the same kind is also spared so retrieval of such associations cannot be sufficient to support within-list temporal order recognition.
The contribution of familiarity to recognition memory is a function of test format when using similar foils
TLDR
Patient Y.R., who suffered hippocampal damage that disrupted recollection but not familiarity, was impaired on a yes/no object recognition memory test with similar foils, adding support to the interpretation of patient data, according to which hippocampusal damage causes a recollection deficit that leads to poor performance on the YN test relative to FCC.
