Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes in ....Preparatory processes in rapid interceptive action. This project investigates the nature of the processes involved in preparing to act in response to a moving object: actions that elite sportspeople perform with amazing precision: timing to within a few thousandths of a second is routine when hitting a ball in tennis and cricket. The average person can be capable of something similar and it means being ready to make the right movement at the right time. Understanding the preparatory processes involved will be a significant scientific advance and knowledge of their workings and limits can contribute to the development of strategies for improving safety in dynamic environments such as city roads. This project will put an Australian laboratory at the cutting edge in this area of research.Read moreRead less
A longitudinal study of neuropsychological and neuromotor effects of low level manganese exposure. This study will investigate the neuropsychological and neuromotor effects of low level exposure to mangenese particulate. Previous studies have indicated symptomology of high level exposure, but there is contention in the literature regarding the effects of low levels of exposure. Our aim is to refine measures of cumulative exposure and develop a more comprehensive and senstitive testing protocol t ....A longitudinal study of neuropsychological and neuromotor effects of low level manganese exposure. This study will investigate the neuropsychological and neuromotor effects of low level exposure to mangenese particulate. Previous studies have indicated symptomology of high level exposure, but there is contention in the literature regarding the effects of low levels of exposure. Our aim is to refine measures of cumulative exposure and develop a more comprehensive and senstitive testing protocol than has been reported thus far. These measures and protocols will be incorporated into a longitudinal design, which has not been conducted in research studies to date. In addition, a database of exposure variables will be developed to facilitate long-term, accurate research into the effects of the low levels of exposure.Read moreRead less
Interceptive Action: Performance, Neuromotor Control and Learning. Natural, everyday environments are dynamic. People, animals and other objects move around and human behaviour must be geared to these motions: people must anticipate where things are going and when they will get there so that undesirable collisions and contacts can be avoided and desirable ones achieved. This project investigates basic modes of interacting with dynamic environments - intercepting and evading objects in motion. T ....Interceptive Action: Performance, Neuromotor Control and Learning. Natural, everyday environments are dynamic. People, animals and other objects move around and human behaviour must be geared to these motions: people must anticipate where things are going and when they will get there so that undesirable collisions and contacts can be avoided and desirable ones achieved. This project investigates basic modes of interacting with dynamic environments - intercepting and evading objects in motion. The aim is to extend our understanding of the principles, control mechanisms and brain structures involved. Such understanding has the potential to contribute to areas such as road safety, autonomous robotics, sports training and neurological rehabilitation.Read moreRead less
Cerebral plasticity or early vulnerability? Identifying critical periods for childhood development and recovery. The primary aim of the study is to identify critical time periods during brain development when an insult will have more deleterious consequences for recovery and outcome. The study will also examine the impact of other potential influences to recovery following early brain disease, and determine whether their impact varies across development. Finally, the study will investigate wh ....Cerebral plasticity or early vulnerability? Identifying critical periods for childhood development and recovery. The primary aim of the study is to identify critical time periods during brain development when an insult will have more deleterious consequences for recovery and outcome. The study will also examine the impact of other potential influences to recovery following early brain disease, and determine whether their impact varies across development. Finally, the study will investigate whether specific cognitive and behavioural domains are differentially effected, depending on their maturity at the time of brain insult. Findings from this study will inform the development of conceptual models of early brain insult and recovery of function, and contribute to clinical practice.Read moreRead less

The Future Fellowship will substantially enhance these activities, building capacity and enhancing Australia's reputation in cognitive neurosciences.Read moreRead less
How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
Learning about threats: the neural and behavioural response to predator-related cues in rodents. This project will investigate the anxiety displayed by rats when confronted with the odours of predators such as cats. This anxiety may be very similar to that experienced by humans who suffer from anxiety disorders such as phobias. By investigating the nature of this anxiety, the nature of the stimuli that produce it, and the learning and neural processes that underlie it we may better understand h ....Learning about threats: the neural and behavioural response to predator-related cues in rodents.

This anxiety may be very similar to that experienced by humans who suffer from anxiety disorders such as phobias. By investigating the nature of this anxiety, the nature of the stimuli that produce it, and the learning and neural processes that underlie it we may better understand human anxiety. The project also aims to identify novel chemicals in the fur of cats that have rodent repellent properties. Such chemicals may be of great use in domestic and agricultural contexts where rodents are pests.Read moreRead less

Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a re ....Neural correlates of performance trade-offs and interference in dual-task performance. Our daily lives are characterised by our ability to produce and sustain a wide range of different movement patterns and to deliberately change patterns as the situation demands. In this project we seek to understand the relationship between brain processes, attentional demands, and the control and learning of coordinated behaviour. A further aim will be to examine how this relationship may be altered as a result of aging, degenerative disease, or brain damage. This research will provide a foundation upon which rehabilitation strategies can be developed for the movement impaired.Read moreRead less
Motor control of the upper airway muscle genioglossus. This project aims to evaluate a recent proposal about the motor control of the upper airway muscle Genioglossus.
