Dopaminergic mechanisms of visual selective attention in the fly. What we pay attention to guides our behaviour. There is increasing evidence that even the smallest animals, such as insects, have a selective attention. Neuromodulators such as dopamine (DA) regulate general arousal states in flies as well as humans, but it is not well understood how DA modulates selective attention. This project will genetically manipulate DA in the fly Drosophila in order to study its role in visual selective at ....Dopaminergic mechanisms of visual selective attention in the fly. What we pay attention to guides our behaviour. There is increasing evidence that even the smallest animals, such as insects, have a selective attention. Neuromodulators such as dopamine (DA) regulate general arousal states in flies as well as humans, but it is not well understood how DA modulates selective attention. This project will genetically manipulate DA in the fly Drosophila in order to study its role in visual selective attention, by: examining neural circuits; attention behaviour; and, brain recordings. Our work will reveal whether DA mainly controls general responsiveness levels, or whether DA is also involved in coordinating attention dynamics. This study has important implications for understanding attention disorders.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
Closing the loop between salience and brain activity. This project aims to understand how animals exposed to an abundance of highly complex information decide what to attend to, that is, how they determine visual saliency. The project will approach this question by systematically tracking visual decision-making in the smallest animal brains, in closed-loop virtual reality environment. This approach will uncover basic working principles applicable to any system that needs to pay attention in a vi ....Closing the loop between salience and brain activity. This project aims to understand how animals exposed to an abundance of highly complex information decide what to attend to, that is, how they determine visual saliency. The project will approach this question by systematically tracking visual decision-making in the smallest animal brains, in closed-loop virtual reality environment. This approach will uncover basic working principles applicable to any system that needs to pay attention in a visually cluttered world, from insects to humans or autonomous vehicles.Read moreRead less
Evolution of cognition and sociality in vertebrates. This project aims to understand better the selective forces shaping cognition and sociality in animals and to determine if 'social intelligence' theory, which predicts more sophisticated cognition as species become increasingly social, provides a general explanation for the evolution of intelligence.
Neuro-ecology: information processing under natural conditions. Not enough is known about how sensory information is processed through the brain under natural environmental conditions. This project will shed light on how information processing changes with context and will help explain why even those animals with the smallest brains are much more versatile and robust than our most advanced robots.
Understanding different speakers vs. different accents: apples and apples or apples and pears? This project will examine how human infants, human adults and songbirds learn the variability in the speech signal and will show whether the underlying skills are uniquely human and specific to certain languages. Converging data using innovative technologies will reveal the details of speech comprehension, an important component of human cognition.
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
Cerebellar control of classical conditioning. This project proposes to use zebrafish, in combination with optogenetics, to identify and test patterns of neural activity that are responsible for classical conditioning. It will do this by describing the connections between the cerebellum and other brain regions, and by observing patterns of neural activity as learning takes place. Next, the project will block or recreate these patterns of activity to see whether they are necessary or sufficient fo ....Cerebellar control of classical conditioning. This project proposes to use zebrafish, in combination with optogenetics, to identify and test patterns of neural activity that are responsible for classical conditioning. It will do this by describing the connections between the cerebellum and other brain regions, and by observing patterns of neural activity as learning takes place. Next, the project will block or recreate these patterns of activity to see whether they are necessary or sufficient for learning. The goal is to describe, in concrete terms, how patterns of neural activity in this part of the brain result in learning. In so doing, the project also aims to develop and test new technologies and approaches for studying the functioning brain.Read moreRead less
Cerebellar control of motor coordination and learning. The cerebellum is the part of the brain responsible for smooth body movements, but many details of how it works are still unclear. This project is aimed at learning how the cerebellum communicates with the rest of the brain, and what parts of this communication are necessary for coordinated movement.
