The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Summary
Deconstructing the brain circuits of reward-seeking. This project aims to deconstruct the brain circuits that shape reward-seeking behaviour in different environments. The anticipated significance of this project is to provide mechanistic insights into why we choose to seek rewards in safe, but not dangerous environments. Expected outcomes include answering fundamental questions about how the environment shapes our behaviour by identifying projection cell subtypes important for reward-seeking, c ....Deconstructing the brain circuits of reward-seeking. This project aims to deconstruct the brain circuits that shape reward-seeking behaviour in different environments. The anticipated significance of this project is to provide mechanistic insights into why we choose to seek rewards in safe, but not dangerous environments. Expected outcomes include answering fundamental questions about how the environment shapes our behaviour by identifying projection cell subtypes important for reward-seeking, characterising their neuronal activity and precisely defining their molecular phenotype. The benefits of this project are expected to provide a new knowledge base for understanding decision-making in a constantly changing world.Read moreRead less
Neural circuit control of effort under stress . This Project aims to investigate how the ‘decision’ to persist in exerting effort to obtain a reward is encoded in the the brain and affected by stress. This work will generate new knowledge on the neural mechanisms through which stress modifies neural activity to control decision making processes underpinning adaptive behaviours essential for survival. The expected outcomes of this work include enhanced capacity at the interface of behavioural a ....Neural circuit control of effort under stress . This Project aims to investigate how the ‘decision’ to persist in exerting effort to obtain a reward is encoded in the the brain and affected by stress. This work will generate new knowledge on the neural mechanisms through which stress modifies neural activity to control decision making processes underpinning adaptive behaviours essential for survival. The expected outcomes of this work include enhanced capacity at the interface of behavioural and computational neuroscience, that will in turn provide significant benefits through greater insight into brain functions essential for survival, with long ranging implications for performance optimisation and brain-inspired computing.

Phenotyping doublecortin+ cells to unravel human adult neurogenesis. This project investigates one of the brain’s most remarkable phenomena: adult neurogenesis, the birth of new brain cells in a specialised brain area (the hippocampus) occurring well into adulthood. This process contributes to many species’ capacity to learn, remember and regenerate. However whether this process occurs in humans is heavily debated. Using new neuroscience tools, this project will produce new insights into human a ....Phenotyping doublecortin+ cells to unravel human adult neurogenesis. This project investigates one of the brain’s most remarkable phenomena: adult neurogenesis, the birth of new brain cells in a specialised brain area (the hippocampus) occurring well into adulthood. This process contributes to many species’ capacity to learn, remember and regenerate. However whether this process occurs in humans is heavily debated. Using new neuroscience tools, this project will produce new insights into human adult neurogenesis by deeply examining hippocampal cells that express the newborn cell marker, doublecortin. This will enable clarification of the existence and extent of adult neurogenesis in humans, and provide the foundation to leverage this process for improving learning, memory and brain regeneration in people.Read moreRead less
Uncovering a novel memory process mediating stimulus-based decisions. The project aims to describe how environmental stimuli influence choice between actions. The goal is to demonstrate that this influence recruits a novel form of memory characterised by a durable change in the expression of an opioid receptor. It will combine sophisticated behavioural tasks with modern genetic tools in rodents to identify the molecular, cellular and neural interactions underlying the acquisition, maintenance an ....Uncovering a novel memory process mediating stimulus-based decisions. The project aims to describe how environmental stimuli influence choice between actions. The goal is to demonstrate that this influence recruits a novel form of memory characterised by a durable change in the expression of an opioid receptor. It will combine sophisticated behavioural tasks with modern genetic tools in rodents to identify the molecular, cellular and neural interactions underlying the acquisition, maintenance and retrieval of this memory. The project expects to provide new insights into the brain machinery promoting motivated behaviours and adaptive decision-making, and to extend knowledge about the physiological underpinnings of our memories.

Gut-brain control of cue-induced feeding behaviours. This proposal aims to determine how food cues (e.g., advertisements) trigger our desire to eat. Using modern virally-mediated strategies, behavioural and histological techniques in a transgenic rat, this proposal seeks to characterise novel gut-brain circuits that mediate cue-induced feeding behaviours. This is significant as food cues can cause overeating, which is problematic in the current obesogenic society, yet the mechanisms are unclear. ....Gut-brain control of cue-induced feeding behaviours.

This is significant as food cues can cause overeating, which is problematic in the current obesogenic society, yet the mechanisms are unclear. This project expects to provide new knowledge on how the gut communicates with multiple brain regions to control cue-induced eating. This work should benefit the advancement of knowledge and establish a framework for future research on gut-brain mechanisms in cue-induced feeding.Read moreRead less
Novel tractography-guided MRI methods for studying healthy brain ageing. Advances in imaging, and particularly Magnetic Resonance Imaging, have opened a new era in the study of the brain enabling a myriad of neuroscience discoveries. This project aims to develop new analysis methods to study and understand the variability in the human brain during ageing, exploiting the wealth of information contained in the so-called tractogram, a mapping of the brain’s wiring.

This project aims to develop new analysis methods to study and understand the variability in the human brain during ageing, exploiting the wealth of information contained in the so-called tractogram, a mapping of the brain’s wiring. This project expects to develop innovative imaging biomarkers to characterise the brain changes in the course of healthy brain ageing. Expected outcomes include novel imaging tools for neuroscience, which should allow us to map trajectories of normative healthy brain ageing and use them to identify lifestyle factors that impact these trajectories.Read moreRead less
