Summary
Autobiographical memory as a key to successful psychological functioning. This project aims to develop a theoretical framework that will explain how the retrieval of autobiographical memories may be essential for good mental health. Using cutting-edge statistical techniques, an international team of researchers will track young adults over a number of years to explore whether autobiographical memory retrieval underlies development of both adaptive and dysfunctional aspects of psychological funct ....Autobiographical memory as a key to successful psychological functioning. This project aims to develop a theoretical framework that will explain how the retrieval of autobiographical memories may be essential for good mental health. Using cutting-edge statistical techniques, an international team of researchers will track young adults over a number of years to explore whether autobiographical memory retrieval underlies development of both adaptive and dysfunctional aspects of psychological functioning. Expected project outcomes will indicate whether future researchers could enhance autobiographical memory to promote healthy development and potentially prevent mental illness from ever emerging. This will allow future researchers to use cognitive science to benefit the mental health of Australians.Read moreRead less
Humans as animals and objects: the psychology of dehumanisation. This project will clarify how some individuals and groups as perceived as less than human. It will examine how some groups are subtly seen as animal-like and how some media images objectify individuals. It will yield a deeper understanding of how people may be degraded, dismissed, vilified and dehumanised.
A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate ....A social psychology of affective disturbance. We are in the midst of a depression and anxiety epidemic that cannot be explained by focusing on individual experiences alone. We desperately need to understand the cultural contributors to depression and anxiety, thereby providing insight into the epidemiology of these conditions. Drawing on experimental studies, longitudinal sampling of daily emotional experiences, and multi-national data, the research will show how cultural contexts may exacerbate individual-level affective disturbance and demonstrate the processes through which occurs. The findings will make a timely and much needed contribution to public policy decisions and preventive health care.Read moreRead less
Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how in ....Mapping, understanding and manipulating the human brain connectome with MRI. The human brain is an extraordinarily complex network, comprising millions of nerve cells connected by trillions of fibres. Understanding this intricate web of connectivity – the so-called human connectome – has become a central goal of neuroscience and is comparable in scale to the human genome project. This project will develop new brain imaging methods for accurately mapping the connectome. It will investigate how information is communicated between its different regions and how individual differences in brain network function relate to our genetic make-up. It will also determine whether we can manipulate the function of specific circuits of the connectome in a targeted way, in the hope of developing new treatments for brain disorders.Read moreRead less
Emotion regulation in daily life: Capturing context and flexibility. This project aims to understand the role of contextual and individual factors in effective emotion regulation in daily life. The ability to manage emotions is central to virtually every aspect of psychosocial functioning and wellbeing. However, because research in this domain has relied heavily on laboratory methods, very little is known about emotion regulation as it naturally occurs in daily life. Using cutting-edge mobile te ....Emotion regulation in daily life: Capturing context and flexibility. This project aims to understand the role of contextual and individual factors in effective emotion regulation in daily life. The ability to manage emotions is central to virtually every aspect of psychosocial functioning and wellbeing. However, because research in this domain has relied heavily on laboratory methods, very little is known about emotion regulation as it naturally occurs in daily life. Using cutting-edge mobile technologies, this project aims to uncover when, and for whom, various forms of emotion regulation are most effective in daily life. Besides a significantly improved scientific understanding of emotion regulation, this project is expected to inform the development of novel person - and situation-specific interventions in the many applied domains involving emotion regulation.Read moreRead less
What is the functional significance of mirror neurons? Contrasting the adaptation and association models of the mirror neuron system. Mirror neurons are a type of brain cell that are thought to underlie empathy and cause autism. Alternatively, however, mirror neurons might instead arise from repeated associations between what we see and what we do. This study uses brain stimulation and neuroimaging techniques to determine the function of mirror neurons.
Multiscale and multimodal modelling of brain dynamics. This project aims to understand dynamics of how several brain regions work together to process information. This project will generate new knowledge in brain sciences by using state of the art computational modelling and neuroimaging methods like functional and diffusion magnetic resonance imaging and electromagnetic measurements. This project will develop technologies to compute multiscale, multimodal and directed connectivity in the brain. ....Multiscale and multimodal modelling of brain dynamics.

Summary
Information processing in the brain. This project aims to understand the brain's functional organisation by developing non-invasive methods to characterise connectivity between interacting brain regions. No model-based methods to compute directional coupling between brain regions can be applied to large scale networks for resting state functional MRI data. This capability would be a major breakthrough in neuroimaging, given uninformative (non-directional) network connectivity analysis restricts ....Information processing in the brain.

Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe ....Investigating the role of Zona Incerta RXFP3+ cells in learning and memory. Learning and memory are fundamental to human and animal behaviour. We identified a specific population of cells in the zona incerta of the brain, where activation inhibits expression of memory, and facilitates the acquisition of new learning. Aside from our observations, nothing is currently known about the anatomy and function of these cells. This project aims to map how they connect to the rest of the brain, to observe how these connections are recruited during learning and memory, and then to test their function experimentally. The outcomes will extend the known neural circuitry that controls learning by defining how and where these unexplored pathways fit within it; thus advancing knowledge regarding neural regulation of behaviour.

Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as pred ....Hunger flexibly modifies hypothalamic neural circuits responding to threat. Animal and human behaviour frequently involves a choice between actions or goals with conflicting positive and negative outcomes. However, the appropriate action or goal in conflicting situations often depends on physiological pressures like hunger, stress and mating opportunities. For example, the need for resources within an environment, such as food, drives approach behaviour, whereas threats to survival, such as predator cues, enhance avoidance behaviour. This project will uncover the neural circuitry and endocrine mechanisms through which hunger influences hypothalamic threat-detecting circuits that suppress food intake. These studies provide a new hypothalamic model to understand risk/reward decision in the brain.Read moreRead less
