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.

Studying The Two Hit Hypothesis Of Psychiatric Illness: Role Of Brain-derived Neurotrophic Factor (BDNF)
Funder

Funding Amount
$314,034.00
Summary
Psychiatric illnesses such as schizophrenia and depression are caused by at least two major disrupting events in development: one during early brain development and one during-after puberty. We will use animal models of schizophrenia, induced by administering stressors such as maternal separation, corticosterone or cannabinoid treatment at different stages of their lives. These animal models will be used to further investigate antipsychotic treatment therapies
Serotonergic Mechanisms Underlying Impulsivity And Vulnerability For Stimulant Addiction
Funder
National Health and Medical Research Council
Funding Amount
$336,318.00
Summary
There is increasing evidence to suggest that impulsivity, a personality trait associated with an increased tendency for premature actions, may predispose individuals to stimulant addiction. The current study employs a non-invasive brain imaging technique in rats – positron emission tomography (PET) – to investigate the implicated role of serotonin (5HT) in impulsivity thereby providing potentially new insights into neural vulnerability mechanisms underlying stimulant addiction.
