The secret of tiny hand movements to feel and manipulate objects. This study aims to reveal some of the fundamental sensory mechanisms underlying the uniquely human ability to manipulate objects and use tools. Signals from touch receptors are crucial for controlling grip forces so that delicate objects are held without slipping, or being crushed by excessive force. Yet we know little about how such sensory information is obtained and how it is used for the motor control.

This study aims to reveal some of the fundamental sensory mechanisms underlying the uniquely human ability to manipulate objects and use tools. Signals from touch receptors are crucial for controlling grip forces so that delicate objects are held without slipping, or being crushed by excessive force. Yet we know little about how such sensory information is obtained and how it is used for the motor control. By analysing hand movements during object manipulation and recording sensory signals from single human nerve fibres we will investigate how certain types of movement shape richness of available sensory information. This knowledge will facilitate the development of next generation sensory-controlled prosthetics and robotic manipulators.Read moreRead less
Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated t ....Functional Assessment of Head-eye Coordination during Driving. 238 people per 100,000 population were hospitalized and 9 people per 100,000 died as a result of road-transport related injury in Australia in 2002. We will address this issue by assessing the head eye coordination strategies for young drivers, for proficient drivers and for aged drivers to determine those behaviors and strategies that are associated with various levels of performance. This insight could be affectively communicated to others and would provide the basis for educational material and methods that would improve operator skill, safety, and performance. These individual improvements would provide overall benefits such as improved transport efficiency, reduced accident rates, saved lives and a reduction in related social costs.Read moreRead less
Nodal Power Saving for Disconnected Ad Hoc Sensor Networks. Bushfire, age care and farming is Australia's today and tomorrow.
A key aspect in bushfire control is early detection of ignitions by spreading miniature low power sensors in a large potential area in an ad hoc fashion and localizing. Response to panic alarm buttons by retirees in a retirement village where they are free to walk around while their location is monitored in real time using a wireless tag they carry to transmit data re ....Nodal Power Saving for Disconnected Ad Hoc Sensor Networks. Bushfire, age care and farming is Australia's today and tomorrow.
A key aspect in bushfire control is early detection of ignitions by spreading miniature low power sensors in a large potential area in an ad hoc fashion and localizing. Response to panic alarm buttons by retirees in a retirement village where they are free to walk around while their location is monitored in real time using a wireless tag they carry to transmit data relating to their physical health(i.e blood pressure, ECG etc). Locating live stocks roaming around in the dairy industry using sensory transmission used for monitoring their statues is vitals for the farmer for improving efficiency.

The effect of multisensory and sensory-motor training on auditory accommodation. Learning to use a hearing aid or cochlear implant requires the brain to make adaptive changes to the new type of sensory information provided to the ears. This project examines what drives this accommodation and how we may accelerate the process and maximise its benefits by training so that listeners are able to make better use of these devices.
Peripheral and central mechanisms of sensory coding and integration. The research described in this proposal seeks to provide generic answers to fundamental questions about sensory processes, the nature of perceptual experience, and how these are subserved by the nervous system. The study of inter-sensory interactions in perception has the potential to be incorporated into the development of virtual reality-type computer-based technologies.

This project aims to advance our understanding of how perceptual information is represented in the human brain and to link the structure of perceptual brain representations to human behaviour. The project plans to use complementary methods for recording brain activity (human neuroimaging and primate single-cell neurophysiology) and cutting-edge analytic techniques to generate a predictive model of behaviour based on the structure of perceptual brain representations. It is anticipated that the results will significantly advance the field of cognitive neuroscience by providing a novel empirical framework for understanding how brain representations are predictive of behaviour.Read moreRead less

This inter-disciplinary project spans behavioural sciences, neurophysiology and computational neuroscience. It investigates fundamental questions such as how different aspects of stimuli are presented in sensory areas of the brain and how the animal interprets the neuronal activity in such areas to generate the relevant behaviour. A major problem with making prosthetic sensory devices is the way by which these devices can communicate with the brain. Research into the coding of different features of simple stimuli will provide basic knowledge which can be implemented in prosthetic sensory devices. Read moreRead less
Identifying the basis for perceptual stability and perceptual omission during saccadic eye movements. The ability to explore the world via eye movements is an important feature of visual capabilities. This project will establish how the brain maintains the perception of a stable and stationary world despite the several eye movements made each second. This knowledge will fill a conspicuous gap in the understanding of the human visual system.
Motion and Spatial Coding in Vision. The results of this project will have implications for the design and implementation of artificial visual systems. Completion of this project will depend upon international collaboration - forging links between a young Australian investigator and outstanding overseas scientists as well as providing excellent training opportunities. Subsequent publication of the research in top-ranking international journals will further promote Australian science abroad.

Our recent work shows that high frequency energy in speech is important for the localisation of speech and may also aid in improving speech intelligibility in noisy environments. The work proposed here will systematically explore this somewhat surprising new finding and the results will be incorporated into a predictive model of speech intelligibility under spatial listening conditions. This work includes a systematic study of auditory functional plasticity to changes in the spatial cues. Taken together, the outcomes of this work will unlock a range of new approaches to enhancing spatial hearing in multi-channel communication devices and spatial hearing aids.Read moreRead less
