This review aims to classify and clarify, from a neuroanatomical, neurophysiological, and psychological perspective, different memory models that are currently widespread in the literature as well as to describe their origins. We believe it is important to consider previous developments without which one cannot…

'Iris E. Martínez-Juárez' 'Yaneth Rodríguez-Agudelo'] The impairment in episodic memory system is the best-known cognitive deficit in patients with temporal lobe epilepsy (TLE). Recent studies have shown evidence of semantic disorders, but they have been less studied than episodic memory. The semantic dysfunction in…

Explicit (declarative) memory, the memory that can be "declared" in words or languages, is made up of two dissociated parts: episodic memory and semantic memory. This dissociation has its neuroanatomical basis—episodic memory is mostly associated with the hippocampus and semantic memory with the neocortex. The two…

Unlike episodic memory, which records personal experiences, semantic memory helps AI build and understand general knowledge . - Non-Parametric Semantic Memory. External knowledge from sources such as knowledge bases allows AI systems to improve their performance on tasks that require objective information, such as…

Episodic and semantic memory are classically thought to play distinct roles: episodic memory encodes unique experiences, while semantic memory generalizes across them. Current conceptualizations of episodic and semantic memory interactions emphasize a one-way consolidation from episodic traces in the medial temporal…

Episodic memory is the recollection of past personal experiences associated with particular times and places. This kind of memory is commonly subject to loss of contextual information or “semantization”, which gradually decouples the encoded memory items from their associated contexts while transforming them into…

Semantic access can occur in many forms, ranging from retrieving specific exemplars to linking concepts with related meanings. We hypothesized that accessing meaning at different levels during encoding would lead to distinct neural reactivation patterns during later memory retrieval. Human participants learned novel…

We analyze perception and memory, using mathematical models for knowledge graphs and tensors, to gain insights into the corresponding functionalities of the human mind. Our discussion is based on the concept of propositional sentences consisting of subject-predicate-object (SPO) triples for expressing elementary facts.…

Semantic knowledge is thought to emerge through the consolidation of episodic experience, yet the biological mechanisms by which reusable semantic representations are extracted from complex episodes remain unclear. Conversely, semantic representations can themselves be found within the medial temporal lobe, raising the…

Semantic relationship modulates working memory (WM) processes by promoting recall but impairing recognition. Updating is a core mechanism of WM responsible for its stability and flexibility; it allows maintenance of relevant information while removing no-longer relevant one. To our knowledge, no studies specifically…

'Robert Logie' 'Rebecca Hart' 'Robert H. Logie' 'Louise A. Brown Nicholls'] Working memory is the system that supports the temporary storage and processing of information. It is generally agreed that working memory is a mental workspace, with a combination of resources operating together to maintain information in mind…

Recent work in vision sciences contends that objects carry an intrinsic property, memorability, that describes the likelihood that an object can be successfully encoded and later retrieved from memory. It has been shown that object memorability is supported by semantic information, but the neural correlates involved…

In this article, we explore various arguments against the traditional distinction between episodic and semantic memory based on the metaphysical phenomenon of transitional gradation. Transitional gradation occurs when two candidate kinds A and B grade into one another along a continuum according to their characteristic…

Large language models (LLMs) face inherent limitations in memory, including restricted context windows [[1]], long-term knowledge forgetting, redundant information accumulation, and hallucination generation [[2]], all of which severely constrain sustained dialogue and personalized services [[3]]. This paper proposes…

Retrieving the relevant information from our knowledge and experiences poses a challenging problem to our memory system. In this study, we explore how retrieval of specific pieces of information from long-term memory is affected by the number of items to be remembered and by the characteristics of retrieval cues.…

Many different studies have suggested that episodic memory is a generative process, but most computational models adopt a storage view. In this work, we propose a computational model for generative episodic memory. It is based on the central hypothesis that the hippocampus stores and retrieves selected aspects of an…

Memories of repeated events are one form of memory thought to be intermediate on a proposed semantic-episodic continuum. However, it is not yet understood where repeated-event memories fall on this continuum, and which factors may be associated with greater or lesser reliance on episodic and semantic memory during…

Declarative memory, or explicit memory, can be fractionated into episodic memory and semantic memory (Tulving, 1972). Episodic memory refers to personally based memories and semantic memory refers to the memory of factual knowledge. The loss of the capacity in retaining episodic memory leads to various amnesias, e.g.…

Object recognition requires integrated processing that extends beyond the visual cortex, incorporating semantic and memory-related processes. However, it remains unclear how different attributes, such as visual, semantic, and memorability features, are encoded and interact during perception. Here, we recorded…

MemPalace is an open-source AI memory system that applies the ancient method of loci (memory palace) spatial metaphor to organize long-term memory for large language models; launched in April 2026, it accumulated over 47,000 GitHub stars in its first two weeks and claims state-of-the-art retrieval performance on the…

Retrieving structured materials information from unstructured textual data is essential for data mining and automatically developing comprehensive ontologies. Information extraction is a complex task composed of multiple subtasks and thus often relies on systems of task-specialized language models. A foundation…

Sample efficiency is a fundamental challenge in de novo molecular design. Ideally, molecular generative models should learn to satisfy desired objectives under minimal oracle evaluations (computational prediction or wet-lab experiment). This problem becomes more apparent when using oracles that can provide increased…
