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.

Neural Basis Of The Functions Of The Primary Visual Cortex: Roles Of Feedforward And Intracortical Inputs
Funder
National Health and Medical Research Council
Funding Amount
$486,280.00
Summary
Signals from the eyes undergo extensive processing at the level of the primary visual cortex so that basic features in the scene such as lines, edges, colours and movement are coded in the activity of individual neurones. This project aims to further our understanding of this process at the basic cellular level. This will not only enable interventions that would help those with poor sight but also give us an insight into basic brain circuitry and its derangement in many neurological disorders.
Mechanisms Underlying Efferent Feedback In The Vestibular System
Funder
National Health and Medical Research Council
Funding Amount
$491,475.00
Summary
The balance system has a remarkable, but poorly understood capacity for self-repair. An intrinsic feedback mechanism, the Efferent Vestibular System or EVS is thought to play a major role in this self-repair. Surprisingly, we know little about EVS function in animals or humans. We will study the EVS in mice and humans to gain a better understanding of how it works. This information will then drive the design of therapies that improve and restore balance in disease, injury, or ageing.
The superior colliculus is a brain centre which uses visual information from the eyes and other sensory information, such as sound, to direct the head and eyes towards objects of interest. This project will use current advancements in optogenetics to activate connections to this brain region in order to understand its role in coordinating head and eye movements. This will advance our understanding of how the brain collects and processes visual information to subserve behavioural functions.
