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.

Accurate Differentiation Of Acquired Speech And Language Disorders For Positive Rehabilitation Outcomes
Funder
National Health and Medical Research Council
Funding Amount
$398,840.00
Summary
Loss of speech due to acquired brain injury causes long-term disability, increased risk for depression, and substantial caregiver burden. Speech disorders can affect linguistic processes or control of speech movements. The current gold standard for diagnosis of speech movement disorders is expert judgment of speech characteristics. We propose to test a novel diagnostic tool that has potential to drive a reframing of rehabilitation strategies to improve outcomes and quality of life.
NEURONAL RESPONSES ELICITED BY VIEWING HUMAN BODY MOTION AND GESTURE.

Funding Amount
$135,822.00
Summary
This project aims to study human brain regions active in viewing movements of the body, face and hands, as well as gestures (i.e. movements with meaning). We will map the location of these human motion sensitive brain regions relative to brain areas dealing with other visual functions. We will use a new method of brain scanning (functional MRI) and recordings of the electrical activity of the brain to achieve these goals. Subjects for this project will be epilepsy patients undergoing investigati ....This project aims to study human brain regions active in viewing movements of the body, face and hands, as well as gestures (i.e. movements with meaning). We will map the location of these human motion sensitive brain regions relative to brain areas dealing with other visual functions. We will use a new method of brain scanning (functional MRI) and recordings of the electrical activity of the brain to achieve these goals. Subjects for this project will be epilepsy patients undergoing investigation for seizure surgery at the A and RMC and Royal Children's Hospitals in Melbourne. Functional MRI - a new non-invasive method for studying brain function - will locate the brain structures involved in the detection and analysis of human motion. Recording electrodes are surgically placed inside the brains of these patients in order to find the source of their seizures, and these electrodes will be utilised for this study. A number of facial, hand and body movement and gestural stimuli will be used. First, brain locations responding to face, hand and body movements will be identified. It is predicted that regions sensitive to hand motion could be located near areas known to participate in adjusting the subject's own visually-guided reaching behaviour. Similarly, regions sensitive to facial motion could be located near areas thought to deal with lip-reading. Second, differences in brain activity to gestures and movements of the face and hand will be studied, so as identify brain regions that process increasingly complex information. Third, differences in brain responses to incompatible (e.g. head facing left and moving right) versus compatible human motion will be studied. A brain 'map' with locations of these human motion sensitive regions relative to visually sensitive regions will be generated. These data will not only aid planning for future seizure surgery, but have implications for our understanding of the visual aspects of motor apraxia.Read moreRead less
From Understanding The Mechanisms To Implementing Conservative Management Of Musculoskeletal Conditions
Funder
National Health and Medical Research Council
Funding Amount
$2,339,215.00
Summary
Musculoskeletal pain is the leading cause of disability internationally and outcomes are worsening. This work will take a unique approach to study back pain from the mechanisms that occur at the cellular level to the interaction between a person’s physiology and psychology to understand why pain fluctuates, to understand how treatments can be more appropriately tailored for individuals, and to test how people with back pain can be supported to change behaviours and achieve recovery.
Harnessing Neural Plasticity To Improve Functional Outcomes Following Burn Injury.
Funder
National Health and Medical Research Council
Funding Amount
$667,984.00
Summary
Burn is painful and leads to long-term functional impairment and increased chronic disease. Pain and peripheral injury induce changes in the brain that can be functionally beneficial or maladaptive, yet we know little about brain changes following burn injury. This project will identify the mechanisms and functional impact of neural plasticity after burn injury, and test the efficacy of a neural intervention to reduce pain and improve functional recovery following burn injury.
Neural Mechanisms Associated With Recovery Of Function Following Motor Cortical Lesions
Funder

Funding Amount
$196,415.00
Summary
Damage to movement control areas in the brain early in life (e.g. cerebral palsy) or in adulthood (e.g. stroke, tumours) results in motor weakness and loss of skill; over a period of many months there is gradual recovery of function. The neural mechanisms that are associated with functional reorganization of the brain and motor recovery are not well understood. This project plans to use animal experiments to identify the location of regions in the brain that undergo neural reorganization and com ....Damage to movement control areas in the brain early in life (e.g. cerebral palsy) or in adulthood (e.g. stroke, tumours) results in motor weakness and loss of skill; over a period of many months there is gradual recovery of function. The neural mechanisms that are associated with functional reorganization of the brain and motor recovery are not well understood. This project plans to use animal experiments to identify the location of regions in the brain that undergo neural reorganization and compensate for lost function. Following brain lesions detailed mapping of the motor areas of the brain and a careful study of movement disabilities will be performed. The study will attempt to identify changes in motor maps that indicate neural reorganization and relate these changes to motor recovery. The results of this study will be used in future projects to test training programs, drugs and neural prosthesis on neural reorganization and recovery of function. Eventually the information may be used to direct pharmacological and physiotherapeutic interventions, and motor rehabilitation programs for optimal recovery of function.Read moreRead less
Volitional And Non-volitional Control Of Human Balance: Normal Physiology And Changes With Ageing
Funder
National Health and Medical Research Council
Funding Amount
$383,066.00
Summary
How does the brain control balance when we stand? Our research shows that two very distinct processes operate to produce distinct postural, perceptual and cardiovascular outcomes. These experiments investigate the neurophysiology that coordinates these systems and what happens with age. The results will fundamentally change views on balance control. Balance problems are common in neurological disorders and old age. Knowing how balance works will improve diagnosis, treatment and rehabilitation.
