Brain Network Dynamics: Function and Mechanisms
Drª Joana Cabral
University of Minho, Portugal
Resumo: ‘Signals detected with functional magnetic resonance imaging (fMRI) correlate across distant brain areas, forming functional networks that appear disrupted in numerous psychiatric and neurological disorders, pointing to a key role in brain function. However, the generative mechanism of fMRI signal correlations are not fully understood. In this talk, I will give an overview of the evidence gathered in the last decade from neuroimaging studies, and describe an emerging mechanistic hypothesis linking these patterns to resonance phenomena. Overall, despite the convincing evidence, it is crucial to obtain a better mechanistic understanding of functional connectivity, in order to design informed strategies to rebalance long-range interactions between brain areas that appear disrupted in disease.’ Joana Cabral Bio:
Joana Cabral entered the course of Biomedical Engineering at FCT-UNL in 2002, the first year that the course opened. During her Master she specialized in neuroimaging analysis and became intrigued by the cryptic signals observed in brain activity across modalities. She did her PhD in Barcelona in Theoretical and Computational Neuroscience, followed by a postdoc at the Department of Psychiatry in Oxford. Joana is now researcher at the University of Minho since 2017 and a visiting researcher at the Champalimaud Foundation since 2019. More than searching for biomarkers in brain activity, Joana is interested in the hidden principles organizing brain activity at the macroscale. Joana has contributed to the field with influential mechanistic models and analysis algorithms, having published over 50 research articles and presented in over 30 international conferences.
