15. Jonathan H. Manton, The University of Melbourne My Background Mathematics ›Differential and algebraic geometry Electrical Engineering ›Signal processing, optimisation, filtering Recently started to learn neuroscience GOAL: To apply mathematics and electrical engineering to understand neurons and the circuitry of the brain How? ›Establish University-wide theme ›Establish CONECT Research Centre

16. Jonathan H. Manton, The University of Melbourne CONECT Research Centre CONECT Centre of Neuro-Engineering and Computation STATUS ›Currently being established ›PhD projects already on offer ›Will bid for funding as an ARC Centre of Excellence ›Will seek additional sources of funding –Government –Industry

17. Jonathan H. Manton, The University of Melbourne Vision (Re-visited) To understand ›High level mechanisms of neuronal circuitry ›Principles behind how neural circuits compute To develop mathematical models at different levels of complexity ›Understand relationships between models ›Understand when each model is appropriate Ultimate goals ›Interface (bi-directionally) with neural circuitry ›Mathematically explain (and reproduce) behaviour and cognition ›Build technology/feature extractors as efficient as the brain ›Cure neurological diseases (e.g. Parkinson’s, epilepsy)

18. Jonathan H. Manton, The University of Melbourne Research Strategy Bring Mathematical and Life sciences together ›Each project will span Faculties: Engineering, Science, Medicine Projects will expand the scope of traditional fields ›Mathematical modelling, System identification, Information theory, Statistical mechanics Rationale: ›Generally accepted that next phase of major breakthroughs will require true cross-disciplinary effort ›Mathematics and physics is a very successful symbiosis. Apply this to the life-sciences and the mathematical sciences

19. Jonathan H. Manton, The University of Melbourne Research Strategy Identified 3 properties of networks and neurons 1. Self-organisation Put 10,000 neurons together and they form a network Repeat experiment and network is different However, networks behave similarly – HOW? 2. Computation What are the basic building blocks used by neural networks in order to compute? How is information stored and transferred? 3. Behaviour How are basic building blocks combined to explain (emergent) behaviour?

20. Jonathan H. Manton, The University of Melbourne Research Strategy The neural circuitry identified to help us understand include ›Enteric nervous system (gut) ›Cultured (in vitro) network ›In vivo networks (e.g. imaging of cortical networks in mice) Technology ›Build imaging devices to probe neural circuitry Theory ›Bring together leading mathematicians, engineers, neuroscientists, etc Experimentation ›Results are grounded on solid experimentation

21. Jonathan H. Manton, The University of Melbourne Example Projects How do random neural networks compute? ›Use probabilistic inputs to artificial neural networks to emulate the behaviour of the brain ›Help us understand how the brain computes Emulating how the nervous system learns ›Person playing sport gets more co-ordinated with time ›Control theory approach to understanding how this happens ›Help us design better adaptive control systems Biophysical models of epileptic networks ›Second most common neurological condition in the world (second only to stroke) ›Understand the onset and offset of seizures via mathematical models

22. Jonathan H. Manton, The University of Melbourne Conclusion Looking for interested collaborators at all levels ›Distinguished visitors, research fellows, PhDs, Masters, Undergraduate Many funding opportunities to be explored ›Local: Industry, Government, University ›International: Exchange programs, collaborative research We are guided by long-term goals and the vision to Understand Neurons and the Circuitry of the brain
