Medial thalamic stroke and its impact on familiarity and recollection
TLDR
Recollection is impaired following MD damage, but familiarity is not, which suggests that models of familiarity, which assign a critical role to the MD, should be reappraised.
Bilateral damage to the mammillo-thalamic tract impairs recollection but not familiarity in the recognition process: A single case investigation

Neural correlates of recollection and familiarity: A review of neuroimaging and patient data
The medial temporal lobe and recognition memory.
TLDR
Evidence from neuropsychological, neuroimaging, and neurophysiological studies of humans, monkeys, and rats indicates that different subregions of the MTL make distinct contributions to recollection and familiarity; the data suggest that the hippocampus is critical for recollection but not familiarity.
Accelerated forgetting of contextual details due to focal medio-dorsal thalamic lesion
TLDR
Assessment of thalamic stroke patients with consistent unilateral lesions focal to the left medio-dorsal nuclei for immediate and delayed memory performance on standard visual and verbal tests of anterograde memory, and over the long-term (>24 h) on an object-location associative memory task suggests a role for theMedio- dorsaluclei in recall and early consolidation memory processes.
Thalamic-medial temporal lobe connectivity underpins familiarity memory
TLDR
Familiarity signals are generated through the dynamic interaction of functionally connected MTL-thalamic structures, and increased functional connectivity between the MDt and the parahippocampal (PHC) and perirhinal cortices of the MTL underpinned increases in reported familiarity confidence.
Thalamic-Medial Temporal Lobe Connectivity Underpins Familiarity Memory
TLDR
Familiarity signals are generated through the dynamic interaction of functionally connected MTL-thalamic structures, and it is shown that the mediodorsal thalamus (MDt) plays a material-general role in familiarity, while the anterior thalamic role in recollection.
The von Restorff Effect in Amnesia: The Contribution of the Hippocampal System to Novelty-Related Memory Enhancements
TLDR
The results indicate that the human medial temporal lobes play a critical role in producing normal novelty effects in memory and are effectively eliminated in patients with extensive medial temporal lobe damage.

Effects of extensive temporal lobe damage or mild hypoxia on recollection and familiarity
TLDR
It is found that the regions disrupted in mild hypoxia, such as the hippocampus, are centrally involved in conscious recollection, whereas the surrounding temporal lobe supports familiarity-based memory discrimination.
Contribution of the Left Dorsomedial Thalamus to Recognition Memory: a Neuropsychological Case Study
TLDR
Cognitive neuropsychological assessment revealed a severe impairment in verbal memory and symptoms of executive dysfunction, in the presence of relatively intact visual and facial recognition, working memory, praxis, language and IQ.
The Nature of Recollection and Familiarity: A Review of 30 Years of Research
To account for dissociations observed in recognition memory tests, several dual-process models have been proposed that assume that recognition judgments can be based on the recollection of details…
On the relationship between recall and recognition memory.
The relationship between recall and recognition has been a central topic for the study of memory. A test of alternative views about recall and recognition was arranged by studying amnesic patients.…
Impaired recognition memory in patients with lesions limited to the hippocampal formation.
TLDR
Recognition memory impairment is a robust feature of human amnesia, even when damage is limited primarily to the hippocampus, and it is shown that recognition memory is impaired after damage limited to the hippocampal region.
Recollection and familiarity deficits in amnesia: convergence of remember-know, process dissociation, and receiver operating characteristic data.
TLDR
A reanalysis of studies using the process dissociation and the remember-know procedures with a dual-process signal-detection model that incorporates response bias revealed that amnesia led to a pronounced reduction in recollection and smaller but consistent reduction in familiarity.
Amnesia in a patient with lesions limited to the dorsomedial thalamic nucleus
TLDR
This case provides strong evidence of a crucial role for the DM in normal memory functioning and an hypothesis which postulates that the DM forms part of a memory system which plays an important role in item recognition in contrast to the hippocampal system which is thought to be crucial for free recall and recognition of associative information.
