Jade Murray, a PhD candidate, won the award for Best PhD Presentation for her work on mood and daytime functioning in intrinsic and extrinsic phenotypes of Delayed Sleep Phase disorder; and Bhairavi Raman, a Psychology Honours student, won the award for Best Honours Presentation for her work examining a the enhancing effects of a short wavelength light intervention on alertness and performance in night shift workers.
Dr Sean Cain’s team awarded NHMRC grant
Dr Sean Cain, Prof Shantha Rajaratnam, Prof Leon Lack, Dr Clare Anderson and Prof Steven Lockley were awarded a NHMRC grant for their Project “Hyper-sensitivity of the circadian system to light in Delayed Sleep Phase Disorder”. Delayed Sleep Phase Disorder (DSPD) is a primary sleep disorder characterized by a difficulty in initiating sleep at night and subsequent difficulty in waking at times required for work or school. DSPD is associated with depression and anxiety, excessive daytime sleepiness, reduced academic and work performance and reduced quality of life, largely due to chronic sleep loss. The physiological basis of the disorder remains unknown, thus hampering efforts to develop accurate diagnostic methods and effective treatments. This project investigates how changes in the sensitivity of the circadian clock to evening light underlie this sleep disorder.

Project Title: Dissecting the neural substrates of spatial attention
Effectively distributing attention in space is critical to human learning and performance. Although it is recognised that spatial attention is influenced by arousal states, we lack an understanding of the associated brain mechanisms and dynamics. This project aims to monitor changes in arousal levels (pupillometry) and discrete stages of information processing (EEG) at the millisecond level during a spatial attention task. Establishing the sensitivity of these methods to spontaneous and externally driven fluctuations of arousal is expected to yield a mechanistic account of the neural substrates of spatial attention with implications for human learning and performance, and diagnosis and treatment of attention disorders.

Project Title: Cognitive Control and Cognitive Compensation in Ageing: Can Older Adults Compensate for Age-Related Changes in the Brain?
Decline in cognitive control can have a devastating effect on an individual's capacity to live a high quality and safe independent life. It is an untested assumption that older adults can compensate for age-related changes in cognitive control function to perform at the same level as younger adults. This project aims to be the first to test this widely-held assumption and will examine changes in cognitive control and the emergence of compensation over the adult lifespan (20 to 90 years). The project aims to establish whether cognitive compensation is an effective mechanism to maintain cognitive control function into old age and will inform future strategies to help older individuals live more successful and productive independent lives for longer.

Project Title: Singing my story: Negotiating identities through therapeutic songwriting for people with acquired neurological injuries
Thousands of Australians present with fractured identities following acquired spinal or brain injuries which can diminish their capacity to participate in and contribute to society. This project aims to investigate the effect of a song writing intervention on reconstruction of a meaningful integrated identity and psychological wellbeing post-injury. It aims to construct a model of mechanisms of change, identify factors influencing change and explore the role of musical identity in the process of identity reconstruction. It is expected that the findings will show evidence that song writing can enhance wellbeing, improve self-concept, and increase social and economic participation in society.
Dr Ben Fulcher awarded a NHMRC Early Career Fellowship
Dr Ben Fulcher was awarded a NHMRC Early Career Fellowship for his project ‘From brain maps to mechanisms: modelling the pathophysiology of schizophrenia’
Schizophrenia is a debilitating neuropsychiatric syndrome associated with delusions, hallucinations, and cognitive and emotional disturbances. Brain imaging techniques such as structural and functional Magnetic Resonance Imaging (MRI, fMRI) have featured prominently in attempts to uncover the neurobiological basis of this debilitating disorder. However, despite an extensive research effort, this work has been unable to identify underlying causes or new treatments, thus having minimal impact on the daily care of patients. Dr Fulcher will develop a framework that integrates brain imaging data with mathematical models of neurophysiological processes, and use it to help understand the neurobiological basis for schizophrenia. The results may be able to link functional Magnetic Resonance Imaging (fMRI) measurements to an understanding of underlying causes in individuals with schizophrenia, and hence motivate new treatments that target them.

MASSIVE help for Neuroscientists
Professor Nellie Georgiou-Karistianis and her team are using the Multi-modal Australian ScienceS Imaging and Visualisation Environment (MASSIVE) to conduct a longitudinal study - The IMAGE-HD study. This project aims to track the onset and progression of Huntington Disease (HD), which will help us to understand how the disease develops over time. Through this research , the team found the number of poorly connected neural networks increased in people diagnosed with HD, compared to those without the disease. They also found that as the disease develops, the changes in the brain become more widespread. These findings have important implications for drug development, particularly in terms of treatments geared toward preventing loss of neural connections, strengthening neural connectivity, and/or improving functional outcomes.
Dr Govinda Poudel, Senior Research Fellow of the IMAGE-HD team, noted that “in the absence of MASSIVE our analysis pipeline would have significantly slowed down – approximately 20 times”. He went on to say the “Parallel processing [capabilities of MASSIVE] allowed us to obtain results for 108 subjects over three time points in a couple of hours rather than days”. MASSIVE has become a significant part of Dr Poudel’s research tool kit…”MASSIVE is an impressive tool, which not only allows rapid analysis but also allows visualisation at a level not possible with other systems.”

Sleep quality critical to the effectiveness of PTSD treatment
Professor Sean Drummond‘s study on the effect of sleep on post-traumatic stress disorder (PTSD) has found that sleep quality is critical to the effectiveness of PTSD treatment. “Our study suggests the physiological mechanism whereby sleep difficulties can help maintain PTSD. It also strongly implies a mechanism by which poor sleep may impair the ability of an individual to fully benefit from exposure-based PTSD treatments, which are the gold standard of interventions.”
“The implication is that we should try treating sleep before treating the daytime symptoms of PTSD and see if those who are sleeping better when they start exposure therapy derive more benefit,” says Professor Drummond.
PTSD is an often difficult-to-treat mental health condition triggered by a terrifying event. Frequently associated with people who have served in war zones, it is characterized by severe anxiety, flashbacks, nightmares, and uncontrollable thoughts.
The study was published in the Journal of Neuroscience.
Professor Drummond is currently professor of psychiatry at the University Of California San Diego School of Medicine and will be joining our school in November.
