Summary
A fundamental question in neuroscience is how the brain selectively processes sensory information to generate a reliable representation of the world. Positioned in the centre of the brain, the thalamus plays a key role in sensory processing. This project investigates how the interaction between thalamus and cortex shapes the selection and gating of sensory information. This is a fundamental question in basic neuroscience with the potential to increase our knowledge about attentional deficits.

A hierarchical quantum mechanical and classical simulation of biological ion channels. I aim to develop a methodology incorporating molecular quantum
mechanics and classical Brownian mechanics in a way that can be
applied practically to large macromolecular systems, thus relating
fine structural details to experimentally measurable

channels in which the challenge is to relate electronic and atomic

determining these relationships provides a pathway to developing cures
for many neurological, cardiac, and muscular diseases.

Summary
Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development. The first objective of this study is to use 3D-motion analysis to ‘probe’ the underlying brain dysfunction which characterises ADHD-CT. The second objective of this study is to improve our understanding of the link between movement problems, and (a) injury proneness, and (b) social-communicative problems, in children with AD ....Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development.

Many Ys in monotremes: multiple sex chromosomes and sex determination in platypus and echidna. Platypus and Echidna are Australian icons, even featuring on our coins. Their unusual biology and ancient relationship to humans make them unique for understanding the mammalian genome, as demonstrated by our recent discovery of ten sex chromosomes in platypus that link mammal and bird sex. Still little is known about their genome, embryo development and how sex is determined. We will identify new gene ....Many Ys in monotremes: multiple sex chromosomes and sex determination in platypus and echidna. Platypus and Echidna are Australian icons, even featuring on our coins. Their unusual biology and ancient relationship to humans make them unique for understanding the mammalian genome, as demonstrated by our recent discovery of ten sex chromosomes in platypus that link mammal and bird sex. Still little is known about their genome, embryo development and how sex is determined. We will identify new genes on all ten sex chromosomes and investigate how they determine sex. The set up of an Australian Monotreme Resource Centre will be crucial for this research and attract worldwide high profile collaborations. We will answer important general questions in monotreme biology and contribute to our understanding of sexual abnormalities in humans.Read moreRead less
Sequence to Sequence: Rigorous Statistical and Mathematical Analysis of Biological Sequence Data. Comparative genomics is fundamental for developing an understanding of genes and their function. For example, using statistical and computational techniques, it was recently demonstrated that 60% of genes are conserved between fly and human. When the human gene that confers susceptibility to Parkinson's disease was transferred into the fly it caused symptoms similar to those seen in humans. The futu ....Sequence to Sequence: Rigorous Statistical and Mathematical Analysis of Biological Sequence Data.

For example, using statistical and computational techniques, it was recently demonstrated that 60% of genes are conserved between fly and human. When the human gene that confers susceptibility to Parkinson's disease was transferred into the fly it caused symptoms similar to those seen in humans. The future development of 'personalized medicine' will rely upon understanding the function of human genes, as will progress in the agricultural sector. Rigorous statistical analysis and development of appropriate bioinformatic methods are crucial to biological sequence analysis in comparative genomics.Read moreRead less
Structural Determinants of an Intracellular Calcium Store. Understanding the molecular interactions between key proteins in calcium signalling in muscle and the heart will allow calcium signalling to be used as a platform for a variety of purposes.

These include reducing the debilitating effects of changes in calcium signalling and muscle performance in aging and in genetically- or drug-induced disorders. The project will have benefits for Australian biotechnology since it will facilitate the design of novel compounds for treating muscle disorders in animals and humans, for improving meat quality and for use as insecticides. The project will facilitate graduate and undergraduate training in basic science with exposure to biotechnology, through our commercial partner Biotron.Read moreRead less

Summary
While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isol ....While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isolated and rejected from the peer group. Also, hand writing problems have a significant impact on children's academic performance. Our previous research has suggested that there may be particular patterns of motor problems that characterise individuals with autism and Asperger's disorder. Our proposed research aims to use the kinds of 3D motion analysis technology used in the movie industry to capture exactly how people affected by these conditions move and respond to the environment. This study will enable us to highlight particular parts of the brain-motor circuitry that are affected by these disorders and will also enable us to more clearly distinguish how autism is different from Asperger's disorder. Ultimately, it is hoped that our motor investigations will lead to improved assessment and interventions for these disorders.Read moreRead less
