Nonhydrostatic waves and instabilities in rotating fluids. This project addresses a fundamental gap in our understanding of the ocean circulation. The benefits of the program will be to improve the way we model and predict the ocean circulation and the response of the ocean to climate change. The project will thereby assist National Research Priorities on global change and link with a major new ANU Marine Science Strategic Initiative.
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
Learning and memory in the honeybee: Task-dependent brain development. We wish to explore whether the development of specific brain regions in young bees depends upon the nature of the learning task in which they are engaged. We will examine tasks that involve two sensory modalities: olfaction and vision, both of which are important to successful foraging. The relative ease with which bees can be trained, and their nervous systems accessed, make them a very attractive subject in which to study f ....Learning and memory in the honeybee: Task-dependent brain development. We wish to explore whether the development of specific brain regions in young bees depends upon the nature of the learning task in which they are engaged. We will examine tasks that involve two sensory modalities: olfaction and vision, both of which are important to successful foraging. The relative ease with which bees can be trained, and their nervous systems accessed, make them a very attractive subject in which to study fundamental principles of learning and memory that may span a variety of organisms.Read moreRead less
Understanding the chemistry and evolution of planets and their atmospheres: Integrating experiments, observations, and quantum mechanical models. Ongoing changes in the Earth's atmosphere, demonstrate the need to understand photochemical processes and their role in atmospheric evolution. The proposed research will increase our understanding of the evolution of planetary atmospheres, with concomitant insight into the Earth's evolution. This proposal will greatly enhance the visibility of Australi ....Understanding the chemistry and evolution of planets and their atmospheres: Integrating experiments, observations, and quantum mechanical models. Ongoing changes in the Earth's atmosphere, demonstrate the need to understand photochemical processes and their role in atmospheric evolution. The proposed research will increase our understanding of the evolution of planetary atmospheres, with concomitant insight into the Earth's evolution. This proposal will greatly enhance the visibility of Australian research, through formal, direct connections to NASA and ESA (European Space Agency) planetary exploration missions, along with publications in Nature, Science, and/or PNAS (Proceedings of the National Academy of Sciences) that will likely result from the high-profile problems to be studied. Furthermore, as a result of this collaboration, Australian students and postdoctoral researchers will benefit from interactions with top international scientists.Read moreRead less
