Role of Parkinson's disease genes in flies

Research outline

Model organisms, like flies, provide a rapid experimental system to study the causes of Parkinson's disease. I collaborate with Sean SweeneyAlex Wade, Gareth Evans, Sangeeta Chawla, Gonzalo Blanco and Will Brackenbury within the York Neuroscience Group, where we focus on neurotransmission in model systems.

My key question is how cellular defects (e.g. faulty mitochondria) lead to physiological and behavioural abnormalities - In Parkinson's Disease (PD), why do some neurons die, while others function normally?



My earlier work at York was with the pond snail Lymnaea stagnalis. This is what the snails look like. In particular, I'm interested in how their nervous system controls feeding behaviour, because this is a really robust model system. A major part of my time was taken up with using laser ablation and pharmacological tools to analyze the neural circuits. My key finding was that octopamine is very important in the feeding system, as it modulates the behaviour at multiple levels, making it more efficient and longer lasting.

Computer Software

I (intermittently) write computer software to aid in the understanding of nervous systems: here is code for analysing Dasylab files and doing SSVEP tests on flies ; read (&download) all about the Hodgkin-Huxley simulation and Connor (with IA) models.
