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 basis of navigation across species

CA Freas, K Cheng - Annual review of psychology, 2022 - annualreviews.org
Animals navigate a wide range of distances, from a few millimeters to globe-spanning
journeys of thousands of kilometers. Despite this array of navigational challenges, similar …

[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 …

Rapid expansion and visual specialisation of learning and memory centres in the brains of Heliconiini butterflies

A Couto, FJ Young, D Atzeni, S Marty… - Nature …, 2023 - nature.com
Abstract Changes in the abundance and diversity of neural cell types, and their connectivity,
shape brain composition and provide the substrate for behavioral evolution. Although …

Neuromorphic sequence learning with an event camera on routes through vegetation

L Zhu, M Mangan, B Webb - Science Robotics, 2023 - science.org
For many robotics applications, it is desirable to have relatively low-power and efficient
onboard solutions. We took inspiration from insects, such as ants, that are capable of …

Transforming a head direction signal into a goal-oriented steering command

EA Westeinde, E Kellogg, PM Dawson, J Lu… - Nature, 2024 - nature.com
To navigate, we must continuously estimate the direction we are headed in, and we must
correct deviations from our goal. Direction estimation is accomplished by ring attractor …

The neuronal building blocks of the navigational toolkit in the central complex of insects

K Pfeiffer - Current Opinion in Insect Science, 2023 - Elsevier
The central complex in the brain of insects is a group of midline-spanning neuropils at the
interface between sensory and premotor tasks of the brain. It is involved in sleep control …

An intrinsic oscillator underlies visual navigation in ants

L Clement, S Schwarz, A Wystrach - Current Biology, 2023 - cell.com
Many insects display lateral oscillations while moving, but how these oscillations are
produced and participate in visual navigation remains unclear. Here, we show that visually …

A unified mechanism for innate and learned visual landmark guidance in the insect central complex

R Goulard, C Buehlmann, JE Niven… - PLoS computational …, 2021 - journals.plos.org
Insects can navigate efficiently in both novel and familiar environments, and this requires
flexiblity in how they are guided by sensory cues. A prominent landmark, for example, can …

Transsynaptic mapping of Drosophila mushroom body output neurons

KM Scaplen, M Talay, JD Fisher, R Cohn, A Sorkaç… - Elife, 2021 - elifesciences.org
The mushroom body (MB) is a well-characterized associative memory structure within the
Drosophila brain. Analyzing MB connectivity using multiple approaches is critical for …
