Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research wi ....Filters reveal what flicker conceals: temporal processing in the human visual system. I have recently discovered a new form of camouflage using 10Hz luminance flicker. This project will quantify this effect and examine the extent to which it generalises across colour and spatial dimensions and to video sequences depicting natural scenes. This information is expected to provide foundational information to technologies relating to national security that rely on visual concealment. This research will examine the extent to which filtering out these camouflaging frequencies enhances our sensitivity to low temporal frequency information. This decamouflaging aspect of my research is expected to improve the clarity of digital video-based technologies including ultrasound, educational, info-tainment and defence applicationsRead 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.

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
Human hippocampus subregions organisation and associative memory processes. This proposal will investigate the hippocampus, a highly inter-connected structure containing many subregions. Although considered the memory centre of the brain, we still do not know the exact roles of these subregions during memory processes.

This proposal will investigate the hippocampus, a highly inter-connected structure containing many subregions. Although considered the memory centre of the brain, we still do not know the exact roles of these subregions during memory processes. Using novel brain neuroimaging acquisition methods and analyses, this project aims to map the internal structure and functions of the hippocampus and its functional networks under different memory conditions and how these functions change with age. The intended outcome of this proposal is to provide the foundations for the first integrated model of human memory and its biological basis and to generate a benchmark against which future development of memory interventions and retraining can be measured.Read moreRead less

The mechanisms driving these changes remain unclear, severely limiting our capacity to accurately assess and optimise memory function in later years. This project aims to determine how memory accuracy and memory quality change across the adult lifespan using cutting-edge experimental and neuroimaging techniques. It will deliver new insights into the relationship between confidence, memory success and memory quality, and the underlying neural substrates of these processes. This work will provide the essential empirical foundation to augment memory function, ensuring that older adults can continue to participate as active members of society.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.
