The project aims to discover the strategies by which cells in the brain interact with each other to code the sensory input efficiently. It is expected that simultaneous recording of the activity of many neurones from the visual cortex of anaesthetised cats during visual stimulation will reveal how the biophysics of synaptic integration combined with excitatory and inhibitory inputs from different sources sculpts the output of individual neurones. The experiments will be extended to the study of possible interactions between different areas of the brain and the study of mechanisms by which the cortical network and higher cognitive factors such as attention and memory might influence the coding of sensory information in awake animals.Read moreRead less

Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to sy ....Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to synthesise sex pheromones. We propose that understanding the chemical and biochemical steps employed by the flies will allow us to design inhibitors to prevent pheromone production and thus provide a novel, species specific method for controlling fruit flies.Read moreRead less
