Pattern recognition in animals and machines: using machine learning to reveal cues central to the identification of individuals. The power to recognise individuals of a species requires significant image and pattern discrimination abilities.

The power to recognise individuals of a species requires significant image and pattern discrimination abilities. Yet, individual recognition has been found in a huge range of species, from humans to invertebrates demonstrating its importance for social interactions. The project will investigate this ability in lower vertebrates (fish, with no visual cortex), so as to understand the underlying mechanisms of pattern discrimination. The project will also test how robust this ability is during changes in water quality (elevated carbon dioxide levels and increased turbidity). The outcomes will further our knowledge base in lower vertebrate vision and evolution, and also have implications for human vision, image analysis, and artificial vision.Read moreRead less
Melanopsin function in humans. This project aims to understand melanopsin signalling in humans. A newly discovered retinal ganglion cell class expresses the melanopsin photopigment. Melanopsin signalling controls neural functions for light dependent image formation and non-image forming processes. Many of these are unknown in humans. This project will use a 5-primary photostimulator to define how melanopsin controls these processes in humans. The outcomes are expected to advance understanding of ....Melanopsin function in humans.

Melanopsin signalling controls neural functions for light dependent image formation and non-image forming processes. Many of these are unknown in humans. This project will use a 5-primary photostimulator to define how melanopsin controls these processes in humans. The outcomes are expected to advance understanding of human vision. This could provide avenues for using light to increase active participation in society and improve health and well-being, and strategies to assess human vision and the body’s internal clock.Read moreRead less
The Helmsman Project: Giving at-risk adolescents skills to navigate life’s journey and make a difference. This project aims to investigate how to keep able but disadvantaged youth engaged in school and give them the psychological tools they need to succeed. To meet this challenge, this project aims to propose a randomised control and extended baseline control test of a combined personal coaching and outdoor education (sailing experience) program designed to foster positive psychological outcomes ....The Helmsman Project: Giving at-risk adolescents skills to navigate life’s journey and make a difference. This project aims to investigate how to keep able but disadvantaged youth engaged in school and give them the psychological tools they need to succeed. To meet this challenge, this project aims to propose a randomised control and extended baseline control test of a combined personal coaching and outdoor education (sailing experience) program designed to foster positive psychological outcomes by developing goal strategies, hope, resilience, and self-regulation. The study aims to be extensive and novel, capturing the experiences of not just the participants but their peers, parents, teachers, and alumni mentors of the program. Both traditional survey and experience sampling data will be collected.Read moreRead less

Summary
A novel approach to modelling nicotine dependence in the rat. With repeated exposure, tobacco smoking can rapidly develop into a habit. How this happens is poorly understood. This project will model the changes to the brain and behaviour of rats during the development of nicotine-seeking habits with a view to better understanding how to reduce tobacco dependence.
Neural origins of conscious perception in no-report paradigms. This project aims to test two highly influential theories of consciousness. The project will be the first to test critical experimental conditions, where neural activities are recorded in humans and novel measures of causality are computed, which allows us to distinguish the two theories. The intended outcomes will provide significant benefits by bringing us closer to solve the mind-body problem. These outcomes can contribute to the ....Neural origins of conscious perception in no-report paradigms. This project aims to test two highly influential theories of consciousness.

The intended outcomes will provide significant benefits by bringing us closer to solve the mind-body problem. These outcomes can contribute to the development of engineering and clinical devices that utilise objective measures of consciousness.Read moreRead less
Testing posterior parietal cortex contributions to human episodic memory. This project aims to determine the involvement of parietal brain regions for episodic memory. Using novel experimental tasks and multimodal neuroimaging techniques in young and healthy aging, this project expects to clarify the role of posterior parietal structures, and their interactions with core memory structures, during memory retrieval. Expected outcomes include advanced understanding of how we remember the past in ri ....Testing posterior parietal cortex contributions to human episodic memory. This project aims to determine the involvement of parietal brain regions for episodic memory. Using novel experimental tasks and multimodal neuroimaging techniques in young and healthy aging, this project expects to clarify the role of posterior parietal structures, and their interactions with core memory structures, during memory retrieval. Expected outcomes include advanced understanding of how we remember the past in rich contextual detail, and how such processes are altered in healthy aging. This potentially provides significant benefits in predicting and treating memory dysfunction due to brain injury or neurodegeneration.Read moreRead less

This project aims to characterise the neurobiology of motivation by combining cutting-edge techniques in psychology, economics, computational modelling and neuroimaging. This project will provide novel mechanistic insights into the brain processes underlying motivation. It will form the basis for international collaborations that significantly advance the frontier field of decision neuroscience, and lay the foundation for future interventions to improve motivation. The results from this project will therefore have wide-ranging translational implications for improving health and socioeconomic outcomes, including workplace productivity and quality of life.Read moreRead less
Neural substrates of higher-order conditioned fear. Higher-order conditioning processes are thought to contribute to the maintenance of maladaptive behaviours such as clinical anxiety, however, little is known about the psychological and neural processes by which this conditioning occurs. Accordingly, this project uses an animal model to investigate these substrates.
The genetic basis of human memory. This project will examine the relationship between genetic variation and performance of normal individuals on a comprehensive range of memory test indicators. Results of the study will clarify the genetic basis of human memory and provide a better understanding of this important function.

Summary
Investigating the evolution of human traits and the maintenance of heritable individual differences. This project will use twin studies, statistical genetics, and experimental methods to investigate genetic and environmental influences on evolutionarily relevant human traits. This will help reveal how human traits evolved and why all individuals are genetically different despite Darwinian selection favouring only the most advantageous genes.
