Awarded Huntington's Disease Society of America (HDSA) HD Human Biology Project Grant
Dr Sophie Andrews and her mentor Professor Julie Stout and collaborator Dr James Coxon awarded grant from Huntington's Disease Society of America (HDSA) HD Human Biology Project Grant. Huntington's disease (HD) is a devastating genetic neurodegenerative disease that usually strikes in mid-life and has no cure. Researchers investigating HD in mice have shown that exercise can increase brain plasticity (the brain’s ability to change and adapt), and delay onset of disease. It is not yet known whether the same is true in humans, or what ‘dose’ (intensity) of exercise is optimal. This project will address this important gap by examining the effect of exercise intensity on brain plasticity and learning in people with early HD, as measured using a safe, non-invasive and painless way to stimulate the brain (transcranial magnetic stimulation), and whether this effect can be enhanced using another type of non-invasive brain stimulation (tDCS). This research is the first step towards providing individuals with the HD gene with evidence-based advice to change their lifestyles before symptoms develop, as well as creating new non-medication interventions for HD.
Royal Science Society of Victoria Young Scientist Award - Runner up
April Philpott. Title: Investigating Neuronal Function Using Brain Stimulation in Huntington's Disease Name: April Philpott, DPsych (Clin Neuro) candidate Supervisors: Prof Nellie Georgiou-Karistianis, Prof Paul Fitzgerald, Dr Tarrant Cummins Organisation: The Royal Society of Victoria Award: Young Scientist Research Prize, Runner Up in the category of Biomedical and Health Sciences Summary of research: Huntington’s disease is an inherited neurodegenerative disorder with onset in middle age. April’s doctoral research study sought to characterise neuronal activity, including excitatory and inhibitory processes, in participants with premanifest and early Huntington’s disease using transcranial magnetic stimulation (TMS). This technique has had limited application in Huntington’s disease to date, but may provide important insights into how neurons progress to death. April’s findings indicated, for the first time, that a disturbance of neuronal function in inhibitory brain circuits occurs approximately 19 years prior to the onset of symptoms. This has important clinical translational benefits, in particular for new treatments options or neuroprotective therapies that might slow down or prevent the onset of this disease.

Dr Claudine Kraan awarded the 2014 Mollie Holman Doctoral Medal
Dr Claudine Kraan, postdoctoral research fellow within the newly established Monash Institute for Cognitive and Clinical Neurosciences (ICCN) is one of only two recipients in the Faculty of Medicine, Nursing and Health Sciences to be awarded a prestigious 2014 Mollie Holman Doctoral Medal for best doctoral thesis.
The Mollie Holman Doctoral Medal was established in 1998 and is named after the late pioneering physiologist Emeritus Professor Mollie Holman AO. It is among the highest academic honours Monash University bestows and marks Dr Kraan as one of its researchers of the highest order.
The award recognises both the quality of Dr Kraan’s thesis and the outstanding quality of her research. In congratulating Dr Kraan on this award, Professor John Caroll, Dean, Subfaculty of Biomedical and Psychological Sciences commented that “Claudine is an outstanding young scientist on track to be a future research leader. Her work includes a number of discoveries on the role of the FMR1 gene in Fragile X Syndrome, a debilitating genetic disease that causes developmental delay in children“.
Dr Claudine Kraan is a postdoctoral research fellow in the lab of Professor Kim Cornish (Head, School of Psychological Sciences and Director, ICCN). Professor Cornish stated that “Claudine is one of the most talented PhD students I have ever had the pleasure to supervise and I am so very proud of her achievements”. Dr Kraan’s research is at the interface of cognitive neuroscience, molecular biology, behavioural epigenetics and psychiatry. She seeks to identify novel relationships between epigenetic status and neuropsychiatric and neurological phenotypes in a highly prevalent group of women that have a premutation expansion of the Fragile X gene (~1 in 150-200 women).
To date, Dr Kraan’s PhD findings have resulted in 10 peer-review publications including Neurology and Neurobiology of Ageing. A co-authored paper recently published in Neurology was lauded as significant in an editorial in Neurology titled ‘Epigenetic diagnostics for neuropsychiatric disorders - Above the genome'.
"Ultimately, the discovery of such epigenotype-phenotype correlations in clinically accessible blood samples with easily scalable, highly quantitative, and inexpensive methodology as used by Cornish et al. is highly likely to assist in the early diagnosis, risk assessment, and patient population stratification for clinical trials in FMR1 premutation subjects," wrote Stephen J. Haggarty, PhD in the editorial.
The School, ICCN and Faculty celebrate this award and congratulate Dr Kraan on this outstanding achievement.

Next generation rising star in HD research
Dr Govinda Poudel is an ECR and an up-and-coming rising star within the School of Psychological Sciences and his recent achievements are a testament to this. For example, in 2015 he was awarded the only Faculty of Medicine, Nursing, and Health Sciences Senior Postdoctoral Fellowship and just recently he was awarded a very prestigious research fellowship for 2 years by the Hereditary Disease Foundation in the USA. In addition, he was awarded a NSW Huntington’s Disease association research grant. The Hereditary Disease Foundation aims to cure genetic illness by supporting basic biomedical research and has identified Dr. Poudel as the next generation rising star in HD research. Dr Poudel has a multidisciplinary background in Engineering and Neurosciences. His research at Monash on the IMAGE-HD study (funded by the CHDI Foundation Inc. USA and NHMRC), mentored by Professor Nellie Georgiou-Karistianis, has made some significant breakthroughs, for example: (i) discovery of specific structural and functional neural pathways disrupted in the early stage of the disease (Poudel et al., 2014 Neurobiology of Disease; Poudel et al., 2014, Journal of Psychiatry and Neuroscience) and (ii) identification of neural processes that provide compensatory benefits prior to the development of symptoms (Poudel et al., 2014, Brain Structure and Function). These findings have major implications for the future development of non-pharmacological interventions that aim to slow down the progression of atrophy in HD. The recent research fellowship awarded by the Hereditary Disease Foundation in the USA will allow Dr. Poudel to focus more on developing novel models of how atrophy spreads in the HD brain and how this relates to the development of overt symptoms.

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.
