Structure and function of heterodimeric amino acid transporters. Recently a new family of amino acid transporters has been identified, the members of which are involved in the delivery of amino acids between cells and tissues. All members display a rather unusual structure in that they require two subunits to be functional. The main aim of this study is to investigate the interaction between large and small subunits. The study will give insight how membrane proteins form complexes in the membran ....Structure and function of heterodimeric amino acid transporters.

All members display a rather unusual structure in that they require two subunits to be functional. The main aim of this study is to investigate the interaction between large and small subunits. The study will give insight how membrane proteins form complexes in the membrane and how these interactions affect the function of a complex membrane protein.Read moreRead less
The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). ....The nature of self-recognition: novel approaches to vexing questions. Mirror self-recognition has often been interpreted as evidence for the presence of some form of self-concept/awareness. Children from age 2 onwards investigate their own bodies after seeing a novel mark on their heads in the mirror (surreptitiously placed in their hair by the experimenter). Younger children and most animals do not respond to their images in such a way (instead, for example, treating it as another individual). The present experiments probe the nature of self-recognition using novel digital video technology rather than mirrors. This technology allows us to manipulate the contingency and appearance of the image. Five studies investigate the performance of 2 to 4-year-old children, autistic children, chimpanzees and dolphins to determine whether they recognize themselves and what underwrites their performance on the tasks. The innovative use of modern technology is expected to answer some of the most persistent questions in psychology.

This application seeks to establish a facility to undertake expression profiling in vertebrate tissues on a genomic scale and at the highest resolution. Undertaking large scale projects of this nature requires specialised robotics and dedicated infrastructure for microscopy and tissue preparation. This facility will be the first of its type in Australia will permit researchers to perform genomic scale in situ screens, many as part of large international initiatives in developmental and cellular biology. This large-scale, high-resolution expression profiling infrastructure is required to maintain international competitiveness and will dramatically improve our gene discovery, functional assessment and understanding of vertebrate development.Read moreRead less
Relationship of the functional architecture of the mammalian brain to its microcircuitry. The project seeks to understand a very fundamental issue in neuroscience: how the connectivity and architecture of the cortex are related to the functions of neurones in that area? This will be investigated by imaging the surface of the visual cortex of anaesthetised cats and monkeys as special visual patterns are shown to the eye/s. The overall picture gained of the active and inactive cortical areas will ....Relationship of the functional architecture of the mammalian brain to its microcircuitry. The project seeks to understand a very fundamental issue in neuroscience: how the connectivity and architecture of the cortex are related to the functions of neurones in that area? This will be investigated by imaging the surface of the visual cortex of anaesthetised cats and monkeys as special visual patterns are shown to the eye/s. The overall picture gained of the active and inactive cortical areas will be related to the properties of neurones in those areas and to those of individual input and output fibres. An optical imaging equipment will be acquired in 2004 using a recently awarded LIEF grant to the CI.Read moreRead less

Organisation of the cerebral cortex- what, if anything, is a cortical area? Currently, much effort is being directed towards elucidating the roles of different regions of the cerebral cortex. "Maps" of cortical areas have become essential points of reference, exerting a powerful influence on the way we think about the brain. However, is it really appropriate to model the cortex as a mosaic of well-defined areas? This project will challenge the assumptions underlying current brain mapping efforts ....Organisation of the cerebral cortex- what, if anything, is a cortical area?

"Maps" of cortical areas have become essential points of reference, exerting a powerful influence on the way we think about the brain. However, is it really appropriate to model the cortex as a mosaic of well-defined areas? This project will challenge the assumptions underlying current brain mapping efforts. Its main benefits will be the refinement of strategies for brain mapping, including potential for better
application/interpretation of available medical technology, and unique insights on the mechanisms of development and evolution of the nervous system.

Assembly of neural circuits during development. This program aims to understand how nerve cells wire up accurately during development. Specifically, the program will determine how neuronal connections are established in the retina to produce a sensory structure essential for vision. The program will also generate innovative tools for watching in live animals, the making and breaking of connections during normal and abnormal development. Discoveries will not only significantly increase our knowle ....Assembly of neural circuits during development. This program aims to understand how nerve cells wire up accurately during development. Specifically, the program will determine how neuronal connections are established in the retina to produce a sensory structure essential for vision. The program will also generate innovative tools for watching in live animals, the making and breaking of connections during normal and abnormal development. Discoveries will not only significantly increase our knowledge base of how the nervous system develops or degenerates, but the results will provide crucial information for future studies based on genetic approaches, drug therapies and bioengineering technology to repair the injured nervous system.Read moreRead less
Functional pathways in primate retina. When light enters the eye, specialised nerve cells called photoreceptors transform the light signal into nerve signals. These signals are processed in the retina by two groups of neurones, bipolar and ganglion cells before being sent to higher brain centres. Bipolar and ganglion cells can be subdivided into several types. We will measure which types communicate with each other and which proteins (neurotransmitter receptors) are involved at the site of commu ....Functional pathways in primate retina.

Bipolar and ganglion cells can be subdivided into several types.

This study will improve our knowledge of the basis of functional subspecialisation at the earliest stages of the visual process.Read moreRead less
