Teaching An Old Brain New Tricks: Optimising Cognitive Training Through Neuroplasticity

Summary
People with early dementia have the most to gain from brain training programs aimed at delaying deterioration. Yet, its power is under-realised, with improvements not generalising to everyday living. This research program will harness the power of neuroplasticity to optimise brain training so that the effects transfer to everyday life. The knowledge gained will transform the way that we design and deliver brain training programs and revolutionise our understanding of why and how people respond.

Summary
‘Glycine’ is an amino acid that can be purchased ‘over the counter’ at health food shops in Australia. Although traditionally administered as a dietary supplement, recently there has been considerable excitement in the psychiatric community due to its ability to improve schizophrenia symptoms when administered in conjunction with mainstream medications.

Although traditionally administered as a dietary supplement, recently there has been considerable excitement in the psychiatric community due to its ability to improve schizophrenia symptoms when administered in conjunction with mainstream medications. However, two issues need to be resolved in order for glycine to be employed as a routine therapy in schizophrenia. Firstly, this treatment is only effective in some patients, and we have no way of determining which patients will benefit from glycine. Secondly, there are both theoretical reasons and experimental evidence that glycine administration can cause severe impairment for some individuals. Thus although there is great potential for glycine to ease the burden of schizophrenia symptoms, these two issues need to be resolved before this possibility can be actualised. Theoretical considerations, supported by pilot research of the investigators, point to the view that schizophrenia patients’ baseline glycine level is the critical factor that determines whether a patient will benefit or be impaired by glycine therapy. This thesis offers a testable means with which to resolve the above limitations to the use of glycine. The purpose of the current research program is thus to provide the basis for rational prescription of glycine as an additional therapeutic tool in schizophrenia.Read moreRead less
Epilepsy is often poorly controlled by medication and dietary measures can be taken that reduce occurrence of epileptic seizures. Glucose control is impacted by diet and also mutations in the genes that move glucose around the body are known to cause epilepsy. Here we will be studying how the genetic and dietary control of glucose levels impacts brain function to increase seizures and to potentially reveal novel therapies.
Underlying Mechanims Of Thalamocortical Dysrhythmia In Chronic Pain

Summary
Pain has a detrimental impact on ones quality of life and a significant financial impact on the community. It has recently been revealed that chronic pain is associated with altered electrical rhythms within the brain. Using human brain imaging, we aim to determine the underlying reason for this altered rhythm in humans with pain resulting from nervous system damage. Defining this mechanism will aid in the development of better treatment regimes.
NeuroGame: Can Neuromodulation Of Brain Rhythms Relieve Chronic Pain?

Funding Amount

Summary
The growing number of overdoses and deaths caused by opioids in the therapy of chronic pain shows the urgent need to develop and test novel chronic pain treatments. We will address this need by developing and testing a novel and safe intervention that can provide pain relief via the primary source of pain: the brain. We will use cutting-edge imaging technology to unravel brain mechanism responsible for the recovery of chronic pain, including efforts to prevent rather than relive chronic pain.
Predicting Clozapine Treatment Response In Psychotic Illness

Summary
Not everyone with a psychotic illness gets better when treated with standard antipsychotic medication. We aim to better understand why some people need a different medicine (clozapine), and to develop methods that will let us identify those people early and monitor how effective the treatment is.
Neurophysiology Of Attention Deficits After Right Hemisphere Stroke

Funding Amount
$611,742.00
Summary
Stroke is a common and debilitating condition affecting thousands of Australians per year. Problems of attention are common after right hemisphere stroke and arise from lesions to multiple different brain regions. This project utilises a unique multi-modal approach to understand the neurophysiology of sensory, attentional, decision-making and motoric aspects of deficit after right hemisphere stroke and will map these objective signatures to discrete lesion locations.

Auditory hallucinations are a prominent and potentially disabling symptom of psychosis, however it is extremely difficult to study them scientifically. Past research by our group (and other groups internationally) has indicated that an extensive network in the brain is activated whenever auditory hallucinations occur, but the source of this brain activity is unclear. It was thought that the source may be the same brain circuits that are involved in generating inner speech or monitoring it, but our past research has ruled out these possibilities. Instead, our recent work suggests that auditory hallucinations may be associated with poorly functioning connections within central auditory processing circuits, specifically between left and right auditory association cortical regions. We conceptualise hallucinations as an abnormal and involuntary form of memory retrieval consequent to this dysfunction. Our study will pioneer methods of measuring connectivity in the brain circuits identified in our model, using a combination of functional magnetic resonance imaging (fMRI) and electroencephalographic (EEG) techniques in tandem with tests of central auditory processing. We believe that sufferers may benefit from understanding the physical processes which cause hallucinations. We also believe that a better understanding of hallucinations may lead to a better understanding of schizophrenia and the psychoses, which may in turn help in the development of better ways of treating these illnesses.Read moreRead less
Establishing The Neural Basis Of Auditory-verbal Hallucinations In Schizophrenia

Funding Amount

Summary
Auditory-verbal hallucinations (AVH) - or hearing voices when no one is talking - are characteristic and debilitating symptoms of schizophrenia. AVH have been hypothesized to reflect inner speech being misperceived as external speech. Our research team has developed an objective brain marker of inner speech. We will use this marker to determine whether AVH are caused by abnormal inner speech in people with schizophrenia. Findings will inform treatments for this incapacitating disorder.
