Beyond mind-reading: multi-voxel pattern analysis of fMRI data
Modeling hippocampal and neocortical contributions to recognition memory: a complementary-learning-systems approach.
TLDR
A computational neural-network model is presented of how the hippocampus and medial temporal lobe cortex contribute to recognition memory and the stochastic relationship between recall and familiarity and the effects of partial versus complete hippocampal lesions on recognition.
A context maintenance and retrieval model of organizational processes in free recall.
The authors present the context maintenance and retrieval (CMR) model of memory search, a generalized version of the temporal context model of M. W. Howard and M. J. Kahana (2002a), which proposes
Shared memories reveal shared structure in neural activity across individuals
TLDR
The results reveal the existence of a common spatial organization for memories in high-level cortical areas, and that neural patterns during perception are altered systematically across people into shared memory representations for real-life events.
Effect of unitization on associative recognition in amnesia
TLDR
The results indicate that unitization may mediate the degree of associative recognition impairment exhibited by some amnesic patients, and that the effect is related to preserved familiarity capacity.
Category-Specific Cortical Activity Precedes Retrieval During Memory Search
TLDR
The reappearance of a given category's activity pattern correlates with verbal recalls made from that category and precedes the recall event by several seconds, consistent with the hypothesis that category-specific activity is cueing the memory system to retrieve studied items.
The cognitive neuroscience of constructive memory.
TLDR
A general integrative framework that outlines the types of problems that the human memory system must solve in order to produce mainly accurate representations of past experience is first described.

TLDR
Simulation results illustrating three critical differences in how hippocampus and cortex contribute to recognition memory, all of which derive from the hippocampus' use of pattern separated representations are reviewed.
A neural network model of retrieval-induced forgetting.
TLDR
A new model of how the brain gives rise to RIF in both semantic and episodic memory is presented, using a recently developed neural network learning algorithm that leverages regular oscillations in feedback inhibition to strengthen weak parts of target memories and to weaken competing memories.
