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.

Importance Of CGRP Alpha In Pain Processing From The Large Intestine
Funder
National Health and Medical Research Council
Funding Amount
$548,289.00
Summary
This project will determine the mechanisms by which sensory nerve endings detect painful stimuli in the large intestine. The project will use a novel genetically modified mouse (that is only available in our laboratory) which allows us, for the first time, to visualize and record directly from the sensory nerve endings that detect painful stimuli and work out how this process occurs. We also identify a specific gene that is essential for detecting painful stimuli from this organ.
Ion Channels Underlying Inflammatory And Post-inflammatory Visceral Mechanical Hypersensitivity
Funder
National Health and Medical Research Council
Funding Amount
$453,439.00
Summary
Inflammation causes tissue damage that triggers ion channels within sensory nerve fibres to produce greater signals in response to mechanical events, causing acute pain. In chronic pain, although the inflamed tissue has healed, sensory nerve fibres fail to "reset" back to normal. Often chronic pain is more severe than acute pain. This project will identify which ion channels are responsible for signalling acute and chronic visceral pain, explaining why sensory nerve fibres fail to reset.
Identifying The Underlying Causes Of Chronic Visceral Pain And Discovering Novel Therapeutic Treatments

Summary
Chronic pain is a major, but under appreciated social, clinical and economic challenge. Globally >1.5 billion people suffer from chronic pain. In the USA alone pain is the leading cause of disability, affecting 115 million adults and costing >$630 billion, more than cancer, heart disease and diabetes combined. By using pre-clinical models and translational science this proposal will identify the key mechanisms underlying chronic pain and also identify novel targets for new therapeutic trea ....Chronic pain is a major, but under appreciated social, clinical and economic challenge.

Development Of Peripheral Sensory Pathways In Humans
Funder
National Health and Medical Research Council
Funding Amount
$477,504.00
Summary
To receive the appropriate information about the state of our muscles, joints, organs, and skin we need a properly 'connected' sensory system. Recent evidence suggests traumatic events during early development can alter sensory connections within the spinal cord. This can lead to debilitating movement disorders, digestive diseases, and increased pain. In this study we will examine how peripheral sensory fibres connect with the appropriate nerve cells in the human spinal cord during development.
Immune Activation In Functional Gastrointestinal Disorders
Funder
National Health and Medical Research Council
Funding Amount
$471,597.00
Summary
Up to 30% of Australians are estimated to suffer from Functional Gastrointestinal Diseases such as Irritable Bowel Syndrome and Functional Dyspepsia, but the cause of these chronic diseases is unknown. Alterations in the immune system are increasingly suggested, but little is known about how this leads to the debilitating symptoms of discomfort and pain. This project combines immunology studies with neuroscience to determine the key mediators involved and how they communicate with nerves.
Pain Systems Analysis Highlights PI3K Gamma As A Candidate Regulator Of Nociception.
Funder
National Health and Medical Research Council
Funding Amount
$461,810.00
Summary
Chronic pain will affect most of us at one point in our life, and there is a need for new drugs to manage this condition. The goal of this project is to use our computer modeling of genetic data from multiple species to predict new drug targets, and then use mouse models to look at the mechanism of action for predicted drug targets, and validate one potential drug target in particular for its therapeutic abilities to stop chronic pain.
Mechanisms Of Body Representation And The Sensory Consequences Of Stroke
Funder
National Health and Medical Research Council
Funding Amount
$408,842.00
Summary
How does the brain control movement without vision? We cannot see our mouth but can easily put food in it. The brain uses a combination of sensory signals and stored models of the body, to control movement. The body models, and their interaction with sensory information, is not well understood. but they are disrupted by common clinical disorders. This research project investigates unsolved questions about the body model including how it is affected by stroke.
Efferent Control Circuitry Of The Auditory Brainstem

Summary
Detection of important sounds within a noisy background is a crucial function of the mammalian hearing system and defects in this function impair social interaction, learning and development. In addition, activity in the brain needs to be carefully regulated by intrinsic circuitry in order to prevent excessive activity responsible for conditions such as tinnitus. The mechanisms by which the brain achieves this are poorly understood and this project aims to improve our understanding of some of th ....Detection of important sounds within a noisy background is a crucial function of the mammalian hearing system and defects in this function impair social interaction, learning and development.
