Does the Entorhinal Cortex use the Fourier Transform?

open access: yesFrontiers in Computational Neuroscience, 2013
Some neurons in the entorhinal cortex (EC) fire bursts when the animal occupies locations organized in a hexagonal grid pattern in their spatial environment.

Spatial representations of place cells in darkness are supported by path integration and border information

open access: yesFrontiers in Behavioral Neuroscience, 2014
Effective spatial navigation is enabled by reliable reference cues that derive from sensory information from the external environment, as well as from internal sources such as the vestibular system.

Reference frames in virtual spatial navigation are viewpoint dependent

open access: yesFrontiers in Human Neuroscience, 2014
Spatial navigation in the mammalian brain relies on a cognitive map of the environment. Such cognitive maps enable us, for example, to take the optimal route from a given location to a known target.

Path integrals of the vector field: Covariance of a path integral

open access: yesProgress 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

Vestibular Loss in Older Adults Is Associated with Impaired Spatial Navigation: Data from the Triangle Completion Task

open access: yesFrontiers in Neurology, 2017
BackgroundVestibular inputs have been shown to play a critical role in spatial navigation. In this study, we sought to evaluate whether vestibular loss due to aging contributes to impaired spatial navigation as measured by the triangle completion task ...

Different Types of Survey-Based Environmental Representations: Egocentric vs. Allocentric Cognitive Maps

open access: yesBrain Sciences, 2023
The goal of the current study was to show the existence of distinct types of survey-based environmental representations, egocentric and allocentric, and provide experimental evidence that they are formed by different types of navigational strategies ...

Speed and Oscillations: Medial Septum Integration of Attention and Navigation

open access: yesFrontiers in Systems Neuroscience, 2017
Several cortical and diencephalic limbic brain regions incorporate neurons that fire in correlation with the speed of whole-body motion, also known as linear velocity.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
