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.

Exercise Reverses Cognitive Decline In Aged Animals By Growth Hormone Stimulation Of Neurogenesis In The Hippocampus

Summary
The production of new neurons in the hippocampus plays a critical role in learning and memory. With increasing age, this production slows and is associated with cognitive decline. However the stem cells that make new neurons are still present, and we have discovered that exercise activates these cells, leading to renewed neuron production and reversal of cognitive decline. We will explore how this process is regulated in order to develop strategies to reduce cognitive decline in humans.
Molecular Mechanisms Of Testosterone Action On Midbrain Dopamine Neuron Differentiation.

Summary
Schizophrenia is characterized by psychosis, social and occupational dysfunction and cognitive deficits. Males are more often diagnosed and more severely impaired than females. Onset in males is most frequent during adolescence, a time of increasing sex hormones. We ask, how do sex hormones act on the adolescent male brain to impact the onset and symptoms of schizophrenia? The answer will allow development of gender and age-specific interventions to prevent onset or ameliorate symptoms.
The Final Common Channel: Measurement Of Nerve Excitability In Epilepsy.

Summary
Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function. It is not possible to directly interrogate channels in the living human brain but, because similar channels are found in peripheral nerve, much may be learned about aberrant channel function from peripheral nerve. This project aims to measure peripheral nerve excitability in epilepsy patients, using it as a marker of the final common pathway of ....Epilepsy may be due to either one single genetic mutation or a combination of several gene-environment interactions, affecting how ion channels function.

Mechanism Of Action Of A Quinazolinone In Models Of PD

Funding Amount

Summary
By the time symptoms of Parkinson's disease (PD) appear, 60-70% of the cells in a crucial part of the brain called the substantia nigra have been destroyed and within a few years of diagnosis, most of the remaining cells have died. This project investigates the causes of this cell loss and a how a new class of compounds could interrupts the process. Success in achieving the aims of this proposal will add to our knowledge of the causes of neuronal death in PD
