Spatial memory is a fundamental cognitive function that enables humans and other species to encode and recall the locations of items in their environments. Humans employ diverse strategies to support spatial memory, including the use of cognitive maps. Cognitive maps are mental representations of the environment that…

Endel Tulving defined episodic memory as consisting of a spatiotemporal context. It enables us to recollect personal experiences of people, things, places, and situations. In other words, it is made up of what, where, and when components. However, this definition does not include arguably the most important aspect of…

During navigation, the brain builds representations of self-motion and of environmental information for future action. The classic view suggests that these representations consolidate and eventually stabilize. However, there are no data on their fate at extended memory delays. Here we investigated memory of real-world…

'Laura Piccardi' 'Raffaella Nori' 'Jose Manuel Cimadevilla' 'Maria Kozhevnikov'] Being able to represent and remember verbally-encoded information about spatial environments from different perspectives is important for numerous daily activities. The present study examined how frequently individuals spontaneously engage…

Spatial cognition enables adaptive goal-directed behavior by constructing internal models of space. Robust biological systems consolidate spatial knowledge into three interconnected forms: landmarks for salient cues, route knowledge for movement trajectories, and survey knowledge for map-like representations. While…

Animals build an internal Bayesian maximum likelihood model of the local 3-D space around them. This 3-D model is essential for controlling all physical movements. There has been large and sustained selection pressure to make it the most precise model possible, given the animal's sense data. A tracking computation has…

A central challenge for working memory is to retain information in a format in which representations remain separated and can be selectively prioritised for behaviour. While it is established that space serves as a foundational “scaffold” for mnemonic individuation, the format and flexibility of spatial scaffolding for…

Spatial memory is invaluable for most mobile organisms, yet nature of the underlying representations that we employ for spatial memory has been fiercely contested. On the one hand, the presence of place cells in the hippocampus and grid cells in the medial entorhinal cortex appear to support the argument spatial…

Episodic memory plays a crucial role in various cognitive processes, such as the ability to mentally recall past events. While cognitive science emphasizes the significance of spatial context in the formation and retrieval of episodic memory, the current primary approach to implementing episodic memory in AI systems is…

The perception, processing, and recall of space- and context-related information has become a major topic in mammalian cognitive neurosciences, following several milestone discoveries: the location-specific activation of “place cells” , the entrainment of such cells into temporal sequences by network oscillations , the…

A theory and neurocomputational model are presented that explain grid cell responses as the byproduct of equally dissimilar hippocampal memories. On this account, place and grid cells are best understood as the natural consequence of memory encoding and retrieval; a precise hexagonal grid is the exception rather than…

Recollection of real-world events is often accompanied by a sense of being in the place where the event transpired. Convergent evidence suggests the hippocampus plays a key role in supporting episodic memory by associating information with the time and place it was originally encountered. This representation is…

A theory and neurocomputational model are presented that explain grid cell responses as the byproduct of equally dissimilar hippocampal memories. On this account, place and grid cells are not best understood as providing a navigational system. Instead, place cells represent memories that are conjunctions of both…

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.…
