Models of grid cell spatial firing published 2005-2011
Frontiers in Neural Circuits, 2012 Since the discovery of grid cells in rat entorhinal cortex, many models of their hexagonally-arrayed spatial firing fields have been suggested. We review the models and organize them according to the mechanisms they use to encode position, update the ...

Frontiers in Neural Circuits, 2012 When rodents engage in irregular foraging in an open field environment, hippocampal principal cells exhibit place-specific firing that is statistically independent of the direction of traverse through the place field.

Path integrals of the vector field: Covariance of a path integral
Progress of Theoretical and Experimental Physics, 2019 On the basis of the canonical quantization procedure of a system defined on a cubic lattice, we propose a new method, in which resolutions of unity expressed in terms of eigenvectors are naturally provided, to find eigenvectors of field operators. By making use of fundamental ingredients thus obtained, we derive time sliced path integral formulae for a

Homing by path integration when a locomotion trajectory crosses itself
, 2014 Path integration is a process with which navigators derive their current position and orientation by integrating self-motion signals along a locomotion trajectory.

Egocentric Navigation Abilities Predict Episodic Memory Performance
Frontiers in Human Neuroscience, 2020 The medial temporal lobe supports both navigation and declarative memory. On this basis, a theory of phylogenetic continuity has been proposed according to which episodic and semantic memories have evolved from egocentric (e.g., path integration) and ...

DISCRETIZATION OF THE SUPERPARTICLE PATH INTEGRAL [PDF]
Modern Physics Letters A, 1993 We investigate the hitherto unexplored relation between the superparticle path integral and superfield theory. Requiring that the path integral has the global symmetries of the classical action and obeys the natural composition property of path integrals, and also that the discretized action has the correct naive continuum limit, we find a viable ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
