Neural networks for navigation: From connections to computations

RI Wilson - Annual Review of Neuroscience, 2023 - annualreviews.org
Many animals can navigate toward a goal they cannot see based on an internal
representation of that goal in the brain's spatial maps. These maps are organized around …

The insect central complex and the neural basis of navigational strategies

A Honkanen, A Adden… - Journal of …, 2019 - journals.biologists.com
Oriented behaviour is present in almost all animals, indicating that it is an ancient feature
that has emerged from animal brains hundreds of millions of years ago. Although many …

[HTML][HTML] A connectome of the Drosophila central complex reveals network motifs suitable for flexible navigation and context-dependent action selection

BK Hulse, H Haberkern, R Franconville… - Elife, 2021 - elifesciences.org
Flexible behaviors over long timescales are thought to engage recurrent neural networks in
deep brain regions, which are experimentally challenging to study. In insects, recurrent …

Transforming representations of movement from body-to world-centric space

J Lu, AH Behbahani, L Hamburg, EA Westeinde… - Nature, 2022 - nature.com
When an animal moves through the world, its brain receives a stream of information about
the body's translational velocity from motor commands and sensory feedback signals. These …

A neural network for wind-guided compass navigation

TS Okubo, P Patella, I D'Alessandro, RI Wilson - Neuron, 2020 - cell.com
Spatial maps in the brain are most accurate when they are linked to external sensory cues.
Here, we show that the compass in the Drosophila brain is linked to the direction of the wind …

AntBot: A six-legged walking robot able to home like desert ants in outdoor environments

J Dupeyroux, JR Serres, S Viollet - Science Robotics, 2019 - science.org
Autonomous outdoor navigation requires reliable multisensory fusion strategies. Desert ants
travel widely every day, showing unrivaled navigation performance using only a few …

Parallel vector memories in the brain of a bee as foundation for flexible navigation

RN Patel, NS Roberts, J Kempenaers, A Zadel… - Proceedings of the …, 2024 - pnas.org
Insects rely on path integration (vector-based navigation) and landmark guidance to perform
sophisticated navigational feats, rivaling those seen in mammals. Bees in particular exhibit …

Fine-grained descending control of steering in walking Drosophila

HH Yang, BE Brezovec, LS Capdevila, QX Vanderbeck… - Cell, 2024 - cell.com
Locomotion involves rhythmic limb movement patterns that originate in circuits outside the
brain. Purposeful locomotion requires descending commands from the brain, but we do not …

A decentralised neural model explaining optimal integration of navigational strategies in insects

X Sun, S Yue, M Mangan - Elife, 2020 - elifesciences.org
Insect navigation arises from the coordinated action of concurrent guidance systems but the
neural mechanisms through which each functions, and are then coordinated, remains …

[HTML][HTML] Walking strides direct rapid and flexible recruitment of visual circuits for course control in Drosophila

T Fujiwara, M Brotas, ME Chiappe - Neuron, 2022 - cell.com
