This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less

This project aims to investigate the neural bases of behaviour in the mammalian gut. The Enteric Nervous System (ENS) plays a critical role in the propulsion of intestinal contents. This project expects to establish how specific functional classes of enteric neurons control propulsion along the gut. By recording the simultaneous neural activity from hundreds of different functional classes of enteric nerve cells simultaneously, whilst recording intestinal muscle electrical activity and the movements of the gut wall, the project expects to identify which enteric neurochemical classes of neurons generate specific motor patterns along the intestine.Read moreRead less
A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in ....A more sound approach to the neurobiology of language. How does the brain attain spoken language? Current neurobiological models assume either implicitly or explicitly that there is no relationship between a word's sound and its meaning. Yet considerable evidence shows this strong assumption about the arbitrariness of language is invalid. This project will use a combination of behavioural, neuroimaging and computational studies to characterise how the brain processes statistical regularities in sound-to-meaning correspondences as probabilistic cues to attain spoken language. The outcome will be a better neural account of language comprehension and production. The benefit of this new account will be a stronger basis for assessment and treatment of developmental and acquired language impairments.Read moreRead less
How Spinal Afferent Neurons Control Appetite and Thirst . This project aims to provide major new insights about how the gut communicates with the brain, to regulate how much food and fluids have been consumed. The proposal expects to generate new knowledge about gut-brain communication and how one of the major sensory nerves from the gut relays information about thirst and appetite sensations. The project addresses fundamental questions that rely on techniques only recently developed in our labo ....How Spinal Afferent Neurons Control Appetite and Thirst . This project aims to provide major new insights about how the gut communicates with the brain, to regulate how much food and fluids have been consumed. The proposal expects to generate new knowledge about gut-brain communication and how one of the major sensory nerves from the gut relays information about thirst and appetite sensations. The project addresses fundamental questions that rely on techniques only recently developed in our laboratory. We expect to demonstrate a major new sensory nerve pathway from the gut to the brain that plays a major role in appetite and thirst sensations. We will learn how gut to brain communication underlies the feeling of "fullness" when people consume food and drink.

This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misfolded proteins during ageing, within the nervous system of a living animal. Expected outcomes of this project will generate new knowledge of brain physiology and ageing relevant to all animals. This should provide significant benefits, such as a greater understanding of long-term brain functions including memory.Read moreRead less

How do researchers learn from and 'think with' non-human organisms? This project seeks to develop a comprehensive historical and philosophical exploration of the changing roles and understandings of research with organisms in 20th and early 21st century science. Advances in the content and technologies of the biological and biomedical sciences have resulted in new understandings of what we can know and learn from organisms, particularly with regard to human functioning, health, and well-being, yet we have no integrated scholarship examining these developments across a range of fields. This project seeks to produce useful scholarship relevant for humanities scholars, scientists, clinicians and policy-makers.Read moreRead less
Early African woodworking and tool use at the transition to modern humans. Our archaeological excavations and preliminary dating of Amanzi Springs (South Africa) to between 515,000 and 163,000 years ago shows that the site covers a critical time period that led to the origins of our species, Homo sapiens.
