![]() “We have long thought that specific thoughts or sensations elicit activity in specific parts of the brain, but this study reveals that structured patterns of activity are excited across nearly the entire brain, just like the way in which a musical note arises from vibrations occurring along the entire length of a violin string, and not just an isolated segment,” he said. “The work opens opportunities to understand the effects of diseases like dementia and stroke by considering models of brain shape, which are far easier to deal with than models of the brain’s full array of connections,” said Dr Pang, who did his PhD at the University of Sydney. Joint lead author and Research Fellow Dr James Pang, from the Turner Institute and Monash University’s School of Psychological Sciences, said the findings were significant because they could simplify the way that we can study how the brain functions, develops and ages. Dr Kevin Aquino, BrainKey and University of Sydney School of Physics.Ĭo-lead author, Dr Kevin Aquino of BrainKey AI and an honorary research fellow at the University of Sydney School of Physics, said: “Just as the resonant frequencies of a violin string are determined by its length, density and tension, the eigenmodes – or oscillating frequencies – of the brain are determined by its structural properties – physical, geometric and anatomical but which specific properties are most important has remained a mystery until now.”
