Membrane excitability and cellular calcium regulation in the peripheral nervous system under different (patho)-physiological conditions and in inflammatory disease. Studies of cytokine action on neurons and muscle give new insights into functional responses of the nervous system to systemic inflammation and sepsis. In some countries, sepsis is the third most frequent cause of death following heart attack. Elucidating the pathomechanisms allows to develop therapeutic strategies.

Studies of cytokine action on neurons and muscle give new insights into functional responses of the nervous system to systemic inflammation and sepsis. In some countries, sepsis is the third most frequent cause of death following heart attack. Elucidating the pathomechanisms allows to develop therapeutic strategies. Electrophysiology, Ca2+ regulation and optical membrane potentiometry allow us to monitor early changes in disease on a (sub)cellular level. Experiments on Ca2+ regulation and ion channel function in muscle with different cholesterol membrane contents will help to understand pathomechanisms in high cholesterol diseases, e.g. obesity, on the membrane level long before cardiovascular effects become prominent.Read moreRead less
Bioinformatics network for the interrogation of adult stem cells. This project addresses the National Research Priority 'Frontier Technologies for Building and Transforming Australian Industries'. The use of state of the art DNA sequencing results in huge amounts of data that is hard to interpret without the use of computers. This project builds Australia's capacity to deal with huge biological datasets by creating software and expertise in handling these datasets. The application of this softwa ....Bioinformatics network for the interrogation of adult stem cells. This project addresses the National Research Priority 'Frontier Technologies for Building and Transforming Australian Industries'. The use of state of the art DNA sequencing results in huge amounts of data that is hard to interpret without the use of computers. This project builds Australia's capacity to deal with huge biological datasets by creating software and expertise in handling these datasets. The application of this software and expertise to our stem cell population in Parkinson's disease patients will enable new insight into the difference between patients and controls.Read moreRead less
How does Motor Cortex Excitability Influence Internal Model Retention. Each year 40,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will result in benefits expressed in terms of enhanced quality of ....How does Motor Cortex Excitability Influence Internal Model Retention. Each year 40,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will result in benefits expressed in terms of enhanced quality of life and functional life-span, as well as significantly reduced costs of health care. In understanding the fundamental principles underlying the stability and adaptability of movement coordination, this research is likely to make a significant contribution to the design of programs for rehabilitation of the upper limb.Read moreRead less
Visuomotor Adaptation and Stimulus Response Compatibility: Basic Mechanisms and Safety Implications for Heavy Equipment. This project will explore mechanisms of human visuomotor adaptation using a directional stimulus-response compatibility (SRC) paradigm. The latter refers to the greatly enhanced performance for ?natural? pairings of control movement directions and system output directions. The outcomes are both theoretical (understanding basic processes) and applied (design and training gui ....Visuomotor Adaptation and Stimulus Response Compatibility: Basic Mechanisms and Safety Implications for Heavy Equipment. This project will explore mechanisms of human visuomotor adaptation using a directional stimulus-response compatibility (SRC) paradigm. The latter refers to the greatly enhanced performance for ?natural? pairings of control movement directions and system output directions. The outcomes are both theoretical (understanding basic processes) and applied (design and training guidelines for equipment in construction, mining, transport and aerospace industries). The issue is also significant both theoretically, since models of adaptation and SRC phenomena have not previously been combined, and practically, as serious heavy equipment accidents can result from designs that are not based on sound human performance principles.Read moreRead less
Is Calcium part of the mechanism used in glucose signalling in embryogenesis. A vital stage in the development of the embryo is formation of the blastocyst about 4 days after conception. For this to happen the embryo must receive glucose from the mother. We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The pr ....Is Calcium part of the mechanism used in glucose signalling in embryogenesis. A vital stage in the development of the embryo is formation of the blastocyst about 4 days after conception. For this to happen the embryo must receive glucose from the mother. We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The project investigates this signal mechanism. The results will advance understanding of the mechanisms regulating development and in particular link the mother's nutritive status to her fertility during very early pregnancy.Read moreRead less
