Summary
Miniaturisation: sensory limitations and navigational competence. Body size in most animals correlates with behavioural competence, brain capacity and sensory receptors. But since the navigational challenges faced by animals both big and small are similar, this project aims to identify the sensory and behavioural costs of miniaturisation and the strategies animals have evolved to cope with it.
Information processing at its limits: from the dimmest habitats to the smallest sizes. Ensuring optimal information processing at the limits of size and ambient light is a challenge for technical systems, but has been elegantly solved by animals. The challenge of navigation is similar for animals of all sizes and in both day and night. This project aims to conduct a comparative analysis to identify the consequence of size and light on the information processing capacities for visual navigation. ....Information processing at its limits: from the dimmest habitats to the smallest sizes. Ensuring optimal information processing at the limits of size and ambient light is a challenge for technical systems, but has been elegantly solved by animals. The challenge of navigation is similar for animals of all sizes and in both day and night. This project aims to conduct a comparative analysis to identify the consequence of size and light on the information processing capacities for visual navigation. Outcomes of this project will reveal the behavioural and physiological adaptations needed and the costs associated with navigating in the dimmest of habitats and at the smallest of sizes. Identifying such optimal biological solutions for robust navigation will be relevant for image processing, computer vision and robotics.Read moreRead less
Navigating brains: the neurobiology of spatial cognition. Navigation is one of the most crucial and most challenging problems animals face. Behavioural analyses have shown that animals make use of a number of different mechanisms to navigate, but very little is known of how different forms of spatial information are processed and integrated by the brain. The project aims to tackle this by placing tethered ants in a virtual-reality simulation of their real environment allowing precise control of ....Navigating brains: the neurobiology of spatial cognition. Navigation is one of the most crucial and most challenging problems animals face. Behavioural analyses have shown that animals make use of a number of different mechanisms to navigate, but very little is known of how different forms of spatial information are processed and integrated by the brain. The project aims to tackle this by placing tethered ants in a virtual-reality simulation of their real environment allowing precise control of visual navigational cues, as well as the opportunity to study the brains of the tethered ants as they solve the real-world challenge of finding home. This may reveal how simple brains efficiently solve navigational tasks, which may inform both cognitive biology and bio-inspired computation.Read moreRead less
Comprehending and modelling the workings of the animal brain. Truly understanding how the brain operates is a grand challenge of 21st century neuroscience. Progress toward this goal can be made through studying small-brained animals, like the honey bee. This project aims to use microscopy and pharmacology to analyse the neural mechanisms by which bees learn and classify complex things. This will enable the construction of a computational model of decision making in the bee brain. Analysing this ....Comprehending and modelling the workings of the animal brain. Truly understanding how the brain operates is a grand challenge of 21st century neuroscience. Progress toward this goal can be made through studying small-brained animals, like the honey bee. This project aims to use microscopy and pharmacology to analyse the neural mechanisms by which bees learn and classify complex things. This will enable the construction of a computational model of decision making in the bee brain. Analysing this model will test what is understood about the operation of the animal brain, and what simulates it. This project aims to reveal how neural circuits make complex decisions; establish key principles and foundational studies for comprehending larger more complex brains, and yield new approaches to machine learning.Read moreRead less

Lattice light sheet microscopy for imaging biology in real space and time. This project aims to establish a Lattice Light-Sheet Microscope (LLSM) Facility, to provide the dedicated computing infrastructure needed for terabyte-scale image acquisition and handling. Lattice light sheet microscopy allows four-dimensional imaging of live biological specimens from individual molecules to small organisms. The microscope images live specimens without phototoxicity or photobleaching, enabling prolonged i ....Lattice light sheet microscopy for imaging biology in real space and time. This project aims to establish a Lattice Light-Sheet Microscope (LLSM) Facility, to provide the dedicated computing infrastructure needed for terabyte-scale image acquisition and handling. Lattice light sheet microscopy allows four-dimensional imaging of live biological specimens from individual molecules to small organisms. The microscope images live specimens without phototoxicity or photobleaching, enabling prolonged imaging of significant physiological or biophysical events. Expected outcomes include high impact discoveries and publications in fundamental research, rapid solutions for industry-focussed projects and opportunities for collaboration, research and development. The imaging is expected to reveal key scientific insights and showcase biology to the public.Read moreRead less
Acquiring and Using Views for Homing. The aim of the project is to investigate how insects acquire and use scene memories for homing, a crucially important task for most animals. In bees and wasps, these memories are acquired during learning flights when leaving the nest. This fast, active learning process underpins much of the insects' navigational competence, but it remains unknown how it is controlled and how in detail memories guide returns to the nest. It is intended to use the latest camer ....Acquiring and Using Views for Homing. The aim of the project is to investigate how insects acquire and use scene memories for homing, a crucially important task for most animals. In bees and wasps, these memories are acquired during learning flights when leaving the nest. This fast, active learning process underpins much of the insects' navigational competence, but it remains unknown how it is controlled and how in detail memories guide returns to the nest. It is intended to use the latest camera-based reconstruction tools for the first time: to quantify the navigational information content of habitats including the visual information available to learning and homing insects, and to dynamically modify the insects’ natural visual environment in order to critically test hypotheses about acquisition and use of views for homing.Read moreRead less
