Summary
My research project involves deconstructing the neural circuitry underlying feeding behaviour using innovative genetically-based methods. I aim to identify and characterise the major projections of the oxytocin-expressing neurons in the paraventricular hypothalamic nucleus, which have recently been identified as critical in the feeding neurocircuitry. This emerging field of research is predicted to transform our understanding and treatment of disorders such as obesity and anorexia nervosa.

Summary
Although the auditory cortex is key to our understanding of several neurological conditions, including language impairments, the functions of many of its areas are still unknown. Using an animal model, we will examine the roles of different auditory areas in separating important sounds from noise. This is a critical role in coordinating our body’s responses to acoustic stimuli. This study will help clarify how these areas contribute to how we normally process sounds, and what deficits are likely ....Although the auditory cortex is key to our understanding of several neurological conditions, including language impairments, the functions of many of its areas are still unknown. Using an animal model, we will examine the roles of different auditory areas in separating important sounds from noise. This is a critical role in coordinating our body’s responses to acoustic stimuli. This study will help clarify how these areas contribute to how we normally process sounds, and what deficits are likely to occur if they are damaged.Read moreRead less
Fluid intake is essential for survival. Disorders of thirst whether they be excessive or inadequate have dire conseqences as evidenced in recent heat waves in Europe and Indiawhere thousands of lives were lost primarily in the elderly whose thirst mechanisms are often disrupted. The excessive fluid intake, seen in psychotic disorders such as schizophrenia, is equally damaging. Much of the research over the last 50 years has concentrated on the hypothalamic regulation of thirst. This project will ....Fluid intake is essential for survival.

The excessive fluid intake, seen in psychotic disorders such as schizophrenia, is equally damaging. Much of the research over the last 50 years has concentrated on the hypothalamic regulation of thirst. This project will attempt, for the first time, to define the location in the cerebral cortex of the drive to ingest water (perception of thirst).Read moreRead less

Summary
There is currently an obesity epidemic in all industrialised countries which has an associated impact on cardiovascular disease and associated pathologies such as type 2 diabetes. Current therapeutic strategies have focussed on reducing food intake but, as evidenced by the continuation of this epidemic, these have had limited success. An alternative approach, which is the subject of this project, is to determine and modify the central mediators controlling energy expenditure. We will bring a raf ....There is currently an obesity epidemic in all industrialised countries which has an associated impact on cardiovascular disease and associated pathologies such as type 2 diabetes. Current therapeutic strategies have focussed on reducing food intake but, as evidenced by the continuation of this epidemic, these have had limited success. An alternative approach, which is the subject of this project, is to determine and modify the central mediators controlling energy expenditure. We will bring a raft of new technologies to examine this question and potentially identify new avenues for therapeutic intervention in obesity.Read moreRead less
