Computational neuroanatomy: analysis of neural connections in the primate brain. This project will map the full network of connections between brain cells, using a computer graphics database that will consolidate data from hundreds of experiments. This will allow the first realistic simulations of neural activity, and will provide new insights about the structure and function of the nervous system.
Understanding complex networks of connections in the primate cerebral cortex. The most fundamental characteristic of brain cells is that they can interchange information through electrical pulses, which run along cable-like membrane specialisations. This creates a hugely complex network of cell-to-cell connections. Understanding this network is necessary to allow new insights on how the brain works as an integrated system, and on how information processing in the brain changes as result of disea ....Understanding complex networks of connections in the primate cerebral cortex. The most fundamental characteristic of brain cells is that they can interchange information through electrical pulses, which run along cable-like membrane specialisations. This creates a hugely complex network of cell-to-cell connections. Understanding this network is necessary to allow new insights on how the brain works as an integrated system, and on how information processing in the brain changes as result of diseases and normal ageing. This project will produce the first comprehensive digital map of the connections in a primate brain. This project will use advanced statistical techniques to determine how to best subdivide the brain into processing nodes, and the logic behind the network of connections that integrates these nodes.

Understanding brain mechanisms that control autonomic function. This project aims to understand the how the brain regulates sympathetic nerve activity, thereby increasing our understanding of the biology and function of nascent neurons on the adult brain stem. This challenges the current notion that new neurons are only made during development. The project will also determine how brain inflammation impacts blood-brain barrier function and affects sympathetic nerve regulation. The basic fundament ....Understanding brain mechanisms that control autonomic function. This project aims to understand the how the brain regulates sympathetic nerve activity, thereby increasing our understanding of the biology and function of nascent neurons on the adult brain stem. This challenges the current notion that new neurons are only made during development. The project will also determine how brain inflammation impacts blood-brain barrier function and affects sympathetic nerve regulation. The basic fundamental insights and conceptual advances into how autonomic function is controlled by the brain will provide a better understanding of these fundamental processes and will contribute to Australia’s priority research areas to improve health and advance product development.Read moreRead less

Summary
Understanding the function of a visual pathway to the limbic cortex. This project will study an area located deep in the brain, about which very little is known. Based on recent studies, it is suspected that this area is important for visual perception. By understanding the patterns of electrical activity of cells in this region, the project aims to decipher its contribution to cognition and emotion.
From gene to duty: the emergence of the complex brain. This project aims to determine the molecular code (genes and their products) responsible for the expansion of the nonhuman primate visual cortex, which underpins the formation of discrete functional and anatomical areas. The project will detail all the genes expressed at key stages of brain development and how interfering with their expression inhibits the normal formation of areas. The expected outcomes are a chronological and functional ma ....From gene to duty: the emergence of the complex brain. This project aims to determine the molecular code (genes and their products) responsible for the expansion of the nonhuman primate visual cortex, which underpins the formation of discrete functional and anatomical areas. The project will detail all the genes expressed at key stages of brain development and how interfering with their expression inhibits the normal formation of areas. The expected outcomes are a chronological and functional map of the molecular code that underpins the formation of the complex primate visual cortex. This will contribute to defining the mechanisms leading to the evolution of the complex primate visual brain and complement the numerous brain connectome studies being undertaken globally.Read moreRead less
Understanding the neuronal mechanisms underlying inherited epilepsies. Epilepsy is a serious disease that impacts severely on individuals and the community as a whole. Conservative estimates suggest a financial cost of more than $2 billion per annum. Drug treatment for this disease is often not adequate.

The cortical location of hunger and thirst: a multifunctional study in sheep. The escalating problems associated with obesity are immense. These effects contribute to a global epidemic that now eclipses both infectious diseases and (ironically) undernutrition in its proportions. The effects of disorders of thirst are less apparent but potentially devastating albeit on a smaller scale.

The escalating problems associated with obesity are immense. These effects contribute to a global epidemic that now eclipses both infectious diseases and (ironically) undernutrition in its proportions. The effects of disorders of thirst are less apparent but potentially devastating albeit on a smaller scale. The elderly and psychotic in the community have impaired thirst mechanisms which impacts on their life in a dramatic way particularly during prolonged hot weather. The aims of these experiments are to understand the basic brain mechanisms that underpin these drives. This understanding will have far reaching repercussions for the community both in terms of promoting good health and in preventative health care.

Being able to see is a crucial aspect of our daily lives, which happens so effortlessly that it tends to be taken for granted. In comparison with other animals and artificial systems, the primate visual cortex is unsurpassed in its capacity to interpret complex and dynamic environments, in a manner that is fast and computationally robust. Discovering how this happens in terms of interactions between cells in the brain can help us design more efficient artificial systems capable of vision. This in turn can have profound implications for the creation of new technologies such as artificial eyes, autonomous robots, and intelligent sensors, and may also result in future benefits for medical science.Read moreRead less
Novel mechanisms for regulating the retinal vasculature. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather they rely on support cells to communicate the needs of neurons. This project aims to examine the mechanisms by which resident immune cells, called microglia, regulate retinal capillaries in response to neural activity.
