Summary
Adolescence is a period of increased vulnerability to anxiety disorders. The brain undergoes substantial maturation during adolescence, particularly the prefrontal cortex (PFC), a region critical for inhibiting fear. This project examines why fear inhibition is impaired in adolescents and compares the neural mechanisms mediating treatments that enhance fear reduction in adolescence. This research adds new knowledge about novel approaches for early interventions for adolescent anxiety.
Non-invasive Detection Of Hypoglycaemia In People With Diabetes Using Brain Wave Activity

Summary
Hypoglycaemia remains a major cause of morbidity and mortality in people with both type 1 diabetes and type 2 diabetes who require insulin therapy. Current treatments for nocturnal hypoglycaemia are usually ineffective. Combining brain wave recording and artificial intelligence, we will identify the changes that precipitate an episode of hypoglycaemia allowing the development of a non-invasive device to prevent or alleviate these fearful and potentially life-threatening events.
Sialyltransferase In The Bipolar And Schizophrenic Brain: Examining The Role Of A Novel Generalised Susceptibility Gene

Summary
Bipolar disorder and schizophrenia are two major psychiatric conditions affecting over 800,000 Australians. We have identified a new gene which contributes to increased risk to developing both bipolar disorder and schizophrenia. We will investigate the function of this gene in normal brain development, and how this function is disrupted in individuals with bipolar disorder and schizophrenia. Understanding the biological cause will help us define better treatments for these severe mental illnesse ....Bipolar disorder and schizophrenia are two major psychiatric conditions affecting over 800,000 Australians.

Regulating Astrocytosis For Appropriate Defence And Repair Of The Brain After Injury

Summary
An inflammatory process, designed to clean up cell debris and maintain tissue integrity following brain insult, also results in an astrocytic scar that biochemically impedes nerve repair. After 8 weeks astrocytes switch to become supportive, however once a scar is formed repair is permanently inhibited. Here, we will test the ability of biomaterials to optimise the timing of the necessary inflammatory phase, to encourage repair by converting astrocytes to their tropic phase more rapidly.
