Mephedrone (Meow, 4-Methylmethcathinone): Examining The Effects Of A Novel Party Drug On Brain And Behaviour
Funder

Funding Amount
$399,796.00
Summary
Mephedrone ("Meow") is a novel recreational drug that has rapidly increased in popularity in recent years. Users report that mephedrone has the stimulant-like qualities of cocaine, combined with the prosocial effects of MDMA. Anecdotal and case study reports indicate that mephedrone may have the potential to engender compulsive patterns of use as well as toxicity in overdose. The current project will use animal models to assess how mephedrone affects the brain and behaviour and to assess its add ....Mephedrone ("Meow") is a novel recreational drug that has rapidly increased in popularity in recent years.

Psychiatric Disorders, Psychotropic Agents And Bone Health: From Benchtop To Bedside.
Funder
National Health and Medical Research Council
Funding Amount
$447,744.00
Summary
Just under half of all people with a psychiatric disorder have a chronic physical illness. One common and neglected comorbidity is osteoporosis. Dr Williams has brought together a multi-disciplinary team of researchers and clinicians that are gathering laboratory through to clinical evidence regarding the interplay between psychiatric disorders, the medication used to treat these disorders and bone health with the aim of informing clinical practice and guiding clinical choice.
Biological And Psychological Health Indices Of Ecstasy/polydrug Users: Testing The Bioenergetic Stress Model
Funder
National Health and Medical Research Council
Funding Amount
$344,015.00
Summary
Use of Ecstasy is increasing in both Australia and the United Kingdom, and is related to poorer psychological and mental functioning in the long-term, suggesting Ecstasy use negatively impacts human physiology producing deficits in aspects of mental functioning. This project aims to assess the effect of weekend use and lifetime use of ecstasy upon measures of physiology and psychology. Findings from these studies may contribute to strategies to reduce the harm associated with Ecstasy use.
Cognitive neuroscience of spatial asymmetry: behaviour, genes and brain imaging. When humans distribute their attention in space, biases or asymmetries of spatial attention exist. Healthy individuals exhibit a processing advantage favouring left space but this advantage is lost in disorders such as unilateral spatial neglect, ADHD and dyslexia. This project will develop novel electrophysiological methods to dissociate the sensory, attentional, decision-making and motoric contributions to spatial ....Cognitive neuroscience of spatial asymmetry: behaviour, genes and brain imaging. When humans distribute their attention in space, biases or asymmetries of spatial attention exist. Healthy individuals exhibit a processing advantage favouring left space but this advantage is lost in disorders such as unilateral spatial neglect, ADHD and dyslexia. This project will develop novel electrophysiological methods to dissociate the sensory, attentional, decision-making and motoric contributions to spatial asymmetries. By interfacing electrophysiology with genetic, neurochemical and brain imaging methods, this project will comprehensively map the biology of spatial asymmetry. This knowledge is vital to developing effective treatments for disorders where atypical patterns of spatial asymmetry index neurological vulnerability.Read moreRead less
Characterising The Effect Of Methamphetamine And Alcohol On Driving Behaviour And Performance
Funder
National Health and Medical Research Council
Funding Amount
$318,768.00
Summary
Methamphetamine and alcohol are commonly detected among drivers involved in road trauma, but it is currently unclear how these substances contribute to an increased crash risk. This series of studies will (1) look at associations between drug use and attitudes and behaviours towards dangerous driving in people who use these drugs. It will also test the effect of combined alcohol and methamphetamine on (2) more complex thinking patterns and behaviours, and (3) objective driving performance.
Vulnerability Markers In The Association Between Cannabis And Schizophrenia
Funder
National Health and Medical Research Council
Funding Amount
$515,764.00
Summary
Understanding the conditions that confer vulnerability to the triggering of schizophrenia by cannabis use is key to preventing transition to psychosis in up to 14% of cases. This project will examine the long- and short-term effects of different cannabis compounds on specific vulnerability markers of brain chemical abnormalities in cannabis users from the general community.
Neural and cognitive studies of reward sensitivity and its influence on addiction-related behaviour. The proposed research aims to contribute to current scientific thinking on the influence of reward sensitivity on cognitive performance. Cognitive neuroscience research on this relationship is of major scientific interest because heightened reward sensitivity is a significant predictor of risk for a number of Australia's major social and economic problems. The findings of this project will contri ....Neural and cognitive studies of reward sensitivity and its influence on addiction-related behaviour. The proposed research aims to contribute to current scientific thinking on the influence of reward sensitivity on cognitive performance. Cognitive neuroscience research on this relationship is of major scientific interest because heightened reward sensitivity is a significant predictor of risk for a number of Australia's major social and economic problems. The findings of this project will contribute to the debate about how to manage such problems.Read moreRead less
