Path-integral evidence [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
Here we present a Bayesian formalism for the goodness-of-fit that is the evidence for a fixed functional form over the evidence for all functions that are a general perturbation about this form. This is done under the assumption that the statistical properties of the data can be modelled by a multivariate Gaussian distribution.

Towards a path dependence approach to study management innovation [PDF]

open access: yes, 2013
Purpose – Scholars in social sciences tend to use the term of path dependence without explaining exactly what they mean by it. Path dependence is a useful approach to understand the success or otherwise of the implementation of management innovation. The

How to Navigate in Different Environments and Situations: Lessons From Ants

open access: yesFrontiers in Psychology, 2018
Ants are a globally distributed insect family whose members have adapted to live in a wide range of different environments and ecological niches. Foraging ants everywhere face the recurring challenge of navigating to find food and to bring it back to the

Eye Movement Reflexes Indicate the Homing Direction in the Path-Integrating Fiddler Crab, Uca pugilator

open access: yesJournal of Marine Science and Engineering, 2023
As animals execute essential behaviors like foraging, they must orient with respect to the space around them, requiring some neural/behavioral mechanism for spatial navigation.

A time-stamp mechanism may provide temporal information necessary for egocentric to allocentric spatial transformations

open access: yeseLife, 2018
Learning the spatial organization of the environment is essential for most animals’ survival. This requires the animal to derive allocentric spatial information from egocentric sensory and motor experience.

Interaction between path integration and visual orientation during the homing run of fiddler crabs [PDF]

open access: yesRoyal Society Open Science, 2017
Foraging fiddler crabs form a strict spatial relationship between their current positions and burrows, allowing them to run directly back to their burrows when startled even without visual contacts.

Resting State Connectivity Between Medial Temporal Lobe Regions and Intrinsic Cortical Networks Predicts Performance in a Path Integration Task

open access: yesFrontiers in Human Neuroscience, 2018
Humans differ in their individual navigational performance, in part because successful navigation relies on several diverse abilities. One such navigational capability is path integration, the updating of position and orientation during movement ...

Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex

open access: yeseLife, 2020
Neuronal representations of spatial location and movement speed in the medial entorhinal cortex during the ‘active’ theta state of the brain are important for memory-guided navigation and rely on visual inputs.

Visual landmarks sharpen grid cell metric and confer context specificity to neurons of the medial entorhinal cortex

open access: yeseLife, 2016
Neurons of the medial entorhinal cortex (MEC) provide spatial representations critical for navigation. In this network, the periodic firing fields of grid cells act as a metric element for position.
