What is the limit of our brain capacity and how can we translate potential brainpower into powerful discoveries? Fernando Calamante from Sydney Imaging talks about mapping structural networks in the brain. Neurologist Michael Barnett, from Brain and Mind Centre, follows on to explain how these networks can be affected in disease. Physicist Céline Boehm explores the recent images of black holes and dark matter. Philosopher David Braddon-Mitchell brings these ideas together, and to close, is a performance by sound artist Benjamin Carey. This conversation was chaired by Duncan Ivison, Deputy Vice-Chancellor of Research at the University of Sydney. It was recorded on Tuesday 20 August at a Sydney Ideas event, as part of Innovation Week 2019, which celebrates landmark discoveries and transformative inventions by the University's academics and students.
