Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investiga ....Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investigate complex motion processing in the primate brain by recording the responses of neurons in identified regions of the visual cortex of macaque monkeys to a range of behaviourally relevant motion stimuli.Read moreRead less
Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches.

Moving to be seen: a comprehensive analysis of movement-based signal design. Papers on visual motion processing and animal signal design regularly feature in major journals, and the programs of international conferences. We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have ....Moving to be seen: a comprehensive analysis of movement-based signal design.

We can thus be confident that theoretical advances will attract international attention. We will develop further state-of-the-art methods in motion analysis, with our overall approach likely to serve as a framework for future research programs, although our techniques will have applications outside of biology. In addition, we will learn much about the social behaviour of a group of native reptiles about which relatively little is known. Research on the social behaviour of animals is readily comprehended by non-specialists and plays an important role in attracting young people to careers in science.Read moreRead less

Vision provides a window into the brain, for studying perception, cognition and consciousness. It is integral to human cultural and social development. It provides opportunities for technological advances in diagnostics, artificial vision, robotics, and surveillance. Vision is therefore crucial to three of the National Priority Areas. The National Vision Network will create a coherent, interactive and innovative research base in the vision sciences, linked to end-users in areas ranging from the art, entertainment and fashion industries, through health and education, to border protection and counter-terrorism.Read moreRead less
Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin abso ....Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin absorbs light: e.g. intermediates such as metarhodopsin and opsin. The molecular knowledge obtained will help us to understand why it is that the visual system recovers so slowly after the eye has experienced very intense light.Read moreRead less
The first stage of vision: transduction and adaptation in retinal photoreceptors. The project aims to provide a detailed understanding of the molecular steps involved in the first stage of vision - the conversion of light into a neural signal in the rod and cone photoreceptors of the retina. The significance of this is that it will explain the initial events that enable us to see, and will help explain the deficits that occur when the process fails. The outcome will be a comprehensive understand ....The first stage of vision: transduction and adaptation in retinal photoreceptors. The project aims to provide a detailed understanding of the molecular steps involved in the first stage of vision - the conversion of light into a neural signal in the rod and cone photoreceptors of the retina. The significance of this is that it will explain the initial events that enable us to see, and will help explain the deficits that occur when the process fails. The outcome will be a comprehensive understanding of how our photoreceptors respond with extreme sensitivity, yet great rapidity, and over an enormous range of light intensities, thus endowing us with our remarkable sense of vision.Read moreRead less

To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about ....To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about efficient rules of good decision making and on a practical level, we may be able to design more flexible, robust and clever machines. Besides being useful in this wider context, the results of our research will thus also contribute to a new and 'sophisticated' appreciation of the cognitive design of animal.Read moreRead less
