Quick Project Snapshot
Utilising insect peptide hormones in the mammalian nervous system
Dissecting neural circuits and assigning function to them is a top priority within neuroscience. Help validate this newest of technologies and demonstrate its power in vitro and in vivo.
We are looking for a high achieving, intelligent and highly motived student to join our team. The successful student will learn advanced techniques including recoverable surgeries in rats and slice electrophysiology. If you have a genuine interest in neuroscience research and want more information about the project (and honours in general) I would welcome an obligation-free, informal chat.

We study the basic neurophysiology underpinning integration of sensory information within the brain. Our focus of study is at the level of the nucleus of the solitary tract (NTS), a region in the brain that first receives signals from visceral organs including those of the cardiovascular, respiratory and gastro intestinal systems. Knowledge about how the brain and internal organs co-ordinate is pertinent to several disease states, autonomic related; hypertension and obesity and mental health; stress and depression.
Sensory signals concerning internal organ function is termed ‘vicserosensory’, blood pressure for example. We study how the neural network within the NTS is organised; how vicserosensory information modifies behaviour (salt appetite) and visceral organ function during disease (hypertension). Equally, how behaviour (stress/depression) and disease (obesity) modify autonomic reflexes to alter visceral organ function.
The primary techniques utilised within the laboratory revolve around in vitro slice electrophysiology. We possess a large skill-set and toolkit to answer a variety of experimental questions including optogentics, chemogenetics, behavioural paradigms (stress), immunohistochemisty, stereotaxic and other recoverable surgeries that frame our synaptic studies within a larger context.

In Systems Neurophysiology we seek to learn how the nervous system controls various bodily functions and how that control is altered in disease. Our disease focus includes not only neurological disorders such as epilepsy and multiple sclerosis, but also how the nervous system impacts on non-neurological diseases such as heart failure and inflammatory diseases. A clear understanding of basic mechanisms is crucial in developing better therapies and reducing the impacts of illness.
