Social buffering of fear inhibition in adolescent rats. Adolescence is an important time when individuals learn to manage stress-related emotions like fear. Peers can help, or hinder, individuals to regulate fear. This project aims to understand how, when, and for whom social buffering of fear regulation occurs during adolescence. It uses a behavioural, pharmacological, and neural approach to explore these issues. The project aims to close the gap in understanding of how social companions affect ....Social buffering of fear inhibition in adolescent rats. Adolescence is an important time when individuals learn to manage stress-related emotions like fear. Peers can help, or hinder, individuals to regulate fear. This project aims to understand how, when, and for whom social buffering of fear regulation occurs during adolescence. It uses a behavioural, pharmacological, and neural approach to explore these issues. The project aims to close the gap in understanding of how social companions affect basic learning and memory processes in an understudied population of adolescents. The expected outcomes of this project include a richer knowledge of how peers shape emotional regulation during development, which will ultimately inform social-based approaches for improving emotion regulation in youth.

Robots as a Social Group: Implications for Human-Robot Interaction. This Project aims to identify psychological factors that can limit the acceptance of robots in the home and workplace. As robots become more pervasive in everyday life, they are also likely to elicit fear, rejection, and even damage. The significance of the Project lies in its social neuroscientific approach to promoting better human-robot interaction by considering robots as a social group. Expect outcomes include theory develo ....Robots as a Social Group: Implications for Human-Robot Interaction. This Project aims to identify psychological factors that can limit the acceptance of robots in the home and workplace. As robots become more pervasive in everyday life, they are also likely to elicit fear, rejection, and even damage. The significance of the Project lies in its social neuroscientific approach to promoting better human-robot interaction by considering robots as a social group. Expect outcomes include theory development about human and robot intergroup acceptance, enhanced institutional and international collaborations, and much needed psychological knowledge for robot designers. Benefits include a detailed understanding of how to increase the acceptance of robots in a wide variety of fields.Read moreRead less
The Biological Role Of The Cadherin Gene FAT In Bipolar Disorder Susceptibility

Summary
Bipolar disorder (manic depressive illness) is a severe mood disorder, with a lifetime prevalence of up to 1%. The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more ....Bipolar disorder (manic depressive illness) is a severe mood disorder, with a lifetime prevalence of up to 1%. The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more clearly the biological basis of bipolar disorder as a necessary prerequisite to improved diagnosis and treatment. The underlying causes of bipolar disorder remain unknown. However, family studies reveal the high heritability of bipolar disorder and this familial clustering provides an opportunity to use genetic approaches to identify the predisposing genes. The long-term aim of our research is to investigate the biology of those genes that either cause or predispose to bipolar disorder. We have previously used genetic approaches to identify the first bipolar disorder susceptibility gene, a cell contact molecule located on chromosome 4 that is from the cadherin family. The aim of this proposal is to understand how this gene contributes to the risk of developing bipolar disorder. This will be achieved by identifying how the cadherin susceptibility gene, termed 'FAT' results in altered properties in laboratory assays or in altered behaviours in animal models. Identifying the genes responsible for bipolar disorder and understanding their contribution to the biological basis of this severe psychiatric condition is essential to translate these discoveries into improvements in the ability to diagnose, treat and prevent the illness.Read moreRead less
Cloning And Characterisation Of A Bipolar Disorder Susceptibility Gene On Chromosome 15q

Summary
Bipolar disorder is a severe mood disorder, characterised by aberrant mood swings resulting in periods of mania and depression. We need to define more clearly the biological basis of bipolar disorder to improve diagnosis and treatment. Bipolar disorder is highly heritabile allowing the use of genetics to identify the predisposing genes. Our aim is to identify a bipolar susceptibility gene on chromosome 15 and to understand how this gene contributes to the risk of developing bipolar disorder.
Psychiatric disorders are associated with considerable social and economic burden which could be reduced if we understood mental health outcomes in high risk populations. This fellowship will use advanced brain imaging to understand the development of mental health disorders in those at high risk of bipolar disorder and dementia.
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.
Kava For The Treatment Of Generalized Anxiety Disorder: A 16-Week Double-Blind RCT

Summary
Herbal medicines play a prominent role in traditional medicine to treat affective disorders (mood and anxiety disorders), however scientific studies are needed to truly assess their effectiveness. This clinical trial is examining the anxiolytic efficacy of Kava in treating chronic anxiety. As current response to antidepressant drugs can be inadequate, Kava may offer an additional affordable, safe, and effective option to reduce anxiety.
A new perspective on how we learn motor skills: two adaptation classes? The capacity to adapt and acquire movement skills is essential for success in almost every aspect of our lives. This project will test the idea that there are two fundamentally distinct classes of motor learning processes in the brain that are driven by different error types. Using brain recordings, robotic perturbation of movement, and novel variations of classical learning paradigms, the project aims to reveal the neurocom ....A new perspective on how we learn motor skills: two adaptation classes? The capacity to adapt and acquire movement skills is essential for success in almost every aspect of our lives. This project will test the idea that there are two fundamentally distinct classes of motor learning processes in the brain that are driven by different error types. Using brain recordings, robotic perturbation of movement, and novel variations of classical learning paradigms, the project aims to reveal the neurocomputational properties of these proposed adaptation classes across a range of sensorimotor learning paradigms. The knowledge gained from this project may identify new strategies for adapting movements that are widely applicable to industry, defence, sport, and health.Read moreRead less
