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

Summary
Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through ....Understanding how the brain combines sensory information. The ease with which we perceive the external world belies the complexity involved in integrating different sensory inputs. How does the brain achieve this fundamental operation? The project will address this question using a multidisciplinary approach that combines computational modelling, brain imaging, and psychophysical techniques. The expected outcomes of the project are a better understanding of how people perceive the world through optimal integration of sensory cues. In addition to advancing basic scientific knowledge, the findings will illuminate perceptual anomalies in normally developing children and will provide a foundation for reducing a debilitating side effect of virtual reality systems known as ‘cybersickness’.Read moreRead less
The rules governing combined rod and cone photoreceptor signalling in visual pathways. The research program investigates vision at dim (mesopic) light levels where rod and cone photoreceptors simultaneously transmit visual information. The interaction between rod and cone signals is not trivial because their different amplitudes, timings and delays significantly change the perceptual qualities of our visual experience. The research addresses fundamental questions about how the retina and brain i ....The rules governing combined rod and cone photoreceptor signalling in visual pathways. The research program investigates vision at dim (mesopic) light levels where rod and cone photoreceptors simultaneously transmit visual information. The interaction between rod and cone signals is not trivial because their different amplitudes, timings and delays significantly change the perceptual qualities of our visual experience. The research addresses fundamental questions about how the retina and brain integrate disparate signals from the rods and cones to produce a homogenous visual percept. New psychophysical and electroretinographic paradigms will independently control the retinal photoreceptors to resolve the long standing problem of how noise modifies signalling and information flow between the retina and visual cortex.Read moreRead less

Summary
The influence of naturalistic context on visual short-term memory. This project aims to understand visual short-term memory in natural visual environments using a combination of behavioural and brain data. Visual short-term memory is thought to be critical to complex cognitive tasks such as learning and problem solving, but how low-level image context and high-level semantic information influence short-term memory is poorly understood. This project will use advanced computational image processin ....The influence of naturalistic context on visual short-term memory. This project aims to understand visual short-term memory in natural visual environments using a combination of behavioural and brain data. Visual short-term memory is thought to be critical to complex cognitive tasks such as learning and problem solving, but how low-level image context and high-level semantic information influence short-term memory is poorly understood. This project will use advanced computational image processing tools, neuro-imaging, and psychophysical experiments to provide a comprehensive analysis of short-term memory in naturalistic images. The expected outcome is a better understanding of the neural bottlenecks that limit short-term memory, and a model that predicts memory constraints in natural visual environments.Read moreRead less
Linking human brain structure to function with ultra-high resolution fMRI. This project will examine the structure and function of the sensory cortex of the human brain using ultra-high resolution functional magnetic resonance imaging (7 Tesla MRI). The project pushes new boundaries for resolution with ultra-high field MRI (7 Tesla) and, as such, will advance techniques for the acquisition, analysis, and computational modelling of high-resolution fMRI brain imaging, providing detail of the funct ....Linking human brain structure to function with ultra-high resolution fMRI. This project will examine the structure and function of the sensory cortex of the human brain using ultra-high resolution functional magnetic resonance imaging (7 Tesla MRI). The project pushes new boundaries for resolution with ultra-high field MRI (7 Tesla) and, as such, will advance techniques for the acquisition, analysis, and computational modelling of high-resolution fMRI brain imaging, providing detail of the functional organisation of the sensory cortex at a level never previously possible in the living human brain. This will provide new understanding of the neural-level networks that underpin attention and touch perception in the human brain.Read moreRead less
Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the ....Multimodal testing for a fast subcortical route for salient visual stimuli. This project aims to uncover links between underlying brain circuitry, uncertainty and consciousness, and perceptions of fear. The project will use a multi-modal combination of brain imaging and neural recording techniques to generate new knowledge about the brain’s processing of biologically relevant information. The expected outcomes will enhance our knowledge of how the brain rapidly and non-consciously prepares the body for potential escape behaviours and of the brain pathways engaged in fear perception. The outcomes have the potential to inform strategies for overcoming anxiety and its effects on daily life, social interactions and workplace productivity.Read moreRead less
Pathways to social cohesion and social change: opinion-based groups and the dynamic formation of identities. This project will update the understanding of political conflict by exploring groups based around shared opinions. It will show that groups are likely to be more successful in their political campaigns when they tie their causes to national and other positive identifies.
Attention and hazard perception while driving: how experts see the scene. All drivers have 'drifted-off' or failed to see something that was clearly in view, yet trained expert drivers appear to rarely experience this. This project aims to understand in both 'normal' drivers and expert drivers, attentional mechanisms that control distraction and the perception of hazards, which is critical to road safety and young driver training.
Building capacity for online counselling for schools: developing and evaluating an online school counselling program. The wellbeing of children and young people is an important goal nationally and school-based online counselling has the potential to directly benefit them. The impact of mental health problems and poor life and career choices in adolescence is undisputed. This project will facilitate access to career and mental health support through technology.
