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.

DCC-Robo Interactions Cooperate To Regulate Callosal Axon Guidance

Summary
In order for the brain to function, the correct connections between neurons must be formed during development. These connections, formed by the axonal processes of neurons, are able to find their synaptic targets by sensing molecular cues within the brain that guide them, by attraction or repulsion, to their target. This proposal investigates how attractive and repulsive signals are received and integrated in neurons to enable axons to find their targets in the brain.
Fibroblast Growth Factors In The Development Of Forebrain Commissures

Funding Amount

Summary
In order to function correctly the two hemispheres of the brain must communicate information. This communication occurs across large fibre tracts called commissures. There are three commissural projections in the forebrain; the corpus callosum, the hippocampal commissure and the anterior commissure. Here we investigate the development of these commissures and provide a comprehensive analysis of the role of several secreted, fibroblast growth factor proteins, in their development.
Neogenin: A Molecular Determinant Of Neural Progenitor Polarity And Function

Funding Amount
$569,296.00
Summary
The neuroepithelium (NEP) contains the embryonic neural stem cells essential for the production of all neurons in the adult brain. Failure in NEP function leads to devastating neural tube defects and syndromes such as epilepsy, schizophrenia, and mental retardation. This project will identify the molecular mechanisms regulating NEP stem cell activity and the birth of new neurons in the embryonic neocortex.
