“…Evidence for grid-cell-like representations in humans has been detected as well (Doeller, Barry, & Burgess, 2010). The cortical circuit for spatial representation thus has multiple functionally distinct components, each dedicated to a highly specific aspect of spatial processing (Stensola & Moser, 2016).…”

Cognitive science today increasingly is coming under the influence of embodied, embedded, extended, and enactive perspectives, superimposed on the more traditional cybernetic, computational assumptions of classical cognitive research. Neuroscience has contributed to a greatly enhanced understanding of brain function within the constraints of the traditional cognitive science approach, but interpretations of many of its findings can be enriched by the newer alternative perspectives. Here, we note in particular how these frameworks highlight the cognitive requirements of an animal situated within its particular environment, how the coevolution of an organism's biology and ecology shape its cognitive characteristics, and how the cognitive realm extends beyond the brain of the perceiving animal. We argue that these insights of the embodied cognition paradigm reveal the central role that “place” plays in the cognitive landscape and that cognitive scientists and philosophers alike can gain from paying heed to the importance of a concept of place. We conclude with a discussion of how this concept can be applied with respect to cognitive function, species comparisons, ecologically relevant experimental designs, and how the “hard problem” of consciousness might be approached, among its other implications.

“…An example of the inseparability of H's role in self-hood and embodiment comes from the discovery of place cells in the hippocampus and grid cells of entorhinal cortex (Stensola & Moser, 2016). This spatial location system must include H in order to allow the brain to know where its body resides in space.…”

An unconscious sense of the body in all higher mammals is located in somatosensory and motor cortices, colloquially referred to as the Homunculus (H). The time has arrived to consider how H might engage in the dimensions of selfhood that go beyond embodiment. Surely, the neural network modules that process various dimensions of selfhood must at least access and interact with the H or a stored memory of it. In this review, I suggest that our traditional understanding of H is much too simplistic. This review specifies a set of experimental approaches that should enlarge our understanding of the brain mechanisms of selfhood.

“…Additionally, while many studies have investigated grid coding during free foraging tasks, a recent study found that introducing reward locations altered the structure of grid cells in medial entorhinal cortex to preferentially represent the reward location (Butler, Hardcastle, & Giocomo, 2019). More generally, other findings have suggested that the involvement of entorhinal cortex in navigation can vary based on environmental features (Barry, Ginzberg, O'keefe, & Burgess, 2012;Stensola & Moser, 2016) and behavioral demands (Rodo, Sargolini, & Save, 2017;Yoo & Lee, 2017). Together, these findings reveal that grid cell coding in the entorhinal cortex is inconsistently hexagonally symmetric, rarely static, and is flexible.…”

Grid coding, spatial representation, and navigation: Should we assume an isomorphism?

Grid cells provide a compelling example of a link between cellular activity and an abstract and difficult to define concept like space. Accordingly, a representational perspective on grid coding argues that neural grid coding underlies a fundamentally spatial metric. Recently, some theoretical proposals have suggested extending such a framework to nonspatial cognition as well, such as category learning. Here, we provide a critique of the frequently employed assumption of an isomorphism between patterns of neural activity (e.g., grid cells), mental representation, and behavior (e.g., navigation). Specifically, we question the strict isomorphism between these three levels and suggest that human spatial navigation is perhaps best characterized by a wide variety of both metric and nonmetric strategies. We offer an alternative perspective on how grid coding might relate to human spatial navigation, arguing that grid coding is part of a much larger conglomeration of neural activity patterns that dynamically tune to accomplish specific behavioral outputs.
