Brainstem And Hypothalamic Function And Anatomy In Migraine
Funder
National Health and Medical Research Council
Funding Amount
$652,828.00
Summary
Migraine is a disabling condition characterized by mostly unilateral throbbing head pain and a range of associated neurological symptoms. The underlying mechanisms responsible for the initiation of migraine remains unknown. We aim to determine brain anatomy and activity patterns in migraineurs throughout the migraine cycle. An understanding of the mechanisms responsible for migraine will aid in better treatment development.
A Brain-based Model Of Anxiety Sensitivity In Panic Disorder

Funding Amount
$402,214.00
Summary
This project will combine advanced brain imaging and brain network modelling to better understand the neurobiology of panic disorder with relevance to its treatment.
Probing Neural Circuits Of Emotion With Ultrafast FMRI And Dynamic Natural Stimuli
Funder
National Health and Medical Research Council
Funding Amount
$306,012.00
Summary
Emotion is central to our everyday experience and forms the backbone of our social relationships. Our understanding on emotion, however, mostly relies on strictly controlled task designs, using highly simplified and/or artificial stimuli. In this project, we propose a new platform to study brain activity underlying natural emotional experience. The design and methodology developed in this proposal will provide fundamental outcomes for understanding emotion disturbances in mental disorders.
Characterising And Modulating Corticostriatal Connectivity In Schizophrenia.
Funder
National Health and Medical Research Council
Funding Amount
$316,449.00
Summary
Schizophrenia is a devastating mental illness that affects approximately 0.5-1% of the population. Many of the symptoms of schizophrenia, such as problems with memory and motivation, remain untreatable. This project will explore the brain processes that underlie memory deficits in people with schizophrenia and investigate the use of non-invasive brain stimulation to improve these impairments. The results from this study will hopefully lead to new treatments for people with schizophrenia.
High-resolution Brain Imaging Of Basal Ganglia Function
Funder
National Health and Medical Research Council
Funding Amount
$589,083.00
Summary
This project will develop new methods for high resolution MRI imaging of the human brain. We will assess functions of deep brain areas known as the basal ganglia that play a critical role in movement planning and co-ordination. Dysfunction within the basal ganglia is responsible for the motor impairments seen in people with Parkinson’s disease. In this project, we will examine changes in basal ganglia function and structure that lead to individual differences in movement control and learning.
Activity In Central Cough Networks In Patients With Cough Hypersensitivity
Funder
National Health and Medical Research Council
Funding Amount
$459,499.00
Summary
Excessive cough associated with an airways disease represents the most common reason for doctor consultations. However, the current therapeutic options for relieving excessive cough are limited. This proposal will provide unprecedented insights into the brain mechanisms that contribute to the development of cough disorders in airways disease.
Magnetic Resonance Imaging Of Structural And Functional Connectivity In Lesion-negative Temporal Lobe Epilepsy Compared To Hippocampal Sclerosis
Funder
National Health and Medical Research Council
Funding Amount
$99,883.00
Summary
Epileptic seizures in the temporal lobe of the brain can affect how the temporal lobe connects to other brain regions. We are using new MRI techniques to investigate these altered connections, in patients who have no other abnormality on their brain scans. Our aim is to find distinctive patterns of altered connectivity, which will help us better understand this type of epilepsy.
Novel Approaches To Improve Cognitive Recovery Following Stroke And Traumatic Brain Injury
Funder
National Health and Medical Research Council
Funding Amount
$344,724.00
Summary
Stroke and traumatic brain injury costs the Australian economy over $13 billion, annually. Both disorders result in impaired cognition that impedes individuals’ return to the community. Current rehabilitation strategies, however, fail to adequately rehabilitate cognitive deficits following these disorders. My fellowship will develop new strategies to improve rehabilitation of cognitive functions by using cutting-edge neuroimaging and electrophysiological techniques.
Neural Signatures Of Disease Spread And Evolution In Motor Neurodegenerative Syndromes
Funder
National Health and Medical Research Council
Funding Amount
$408,768.00
Summary
A lack of understanding of the earliest changes brought on by motor neurone disease (MND), otherwise known as amyotrophic lateral sclerosis (ALS), prevents early diagnosis and therapeutic intervention. The proposed project aims to comprehensively characterise neurological changes prior to disease onset in pre-symptomatic carriers with a known genetic mutation linked to MND using targeted neuropsychological assessments and advanced multi-modal neuroimaging to track disease progression.
Neuronal Activity And Functional Magnetic Resonance Imaging (fMRI)
Funder
National Health and Medical Research Council
Funding Amount
$367,561.00
Summary
How does brain activity relate to perception and behaviour? How does functional magnetic resonance imaging (fMRI) of the brain, which measures changes in blood oxygen, relate to the activity of single cells? I will address these questions, comparing electrical measurements of single cells and functional images, and advance our understanding of the brain in health and disease.
