DESCRIPTION:*Speaker:* Visiting in person - Dr Rezvan Farahibozorg\, Unive
 rsity of Oxford\, UK\n\n*Title:* Probabilistic Functional Modes: populatio
 n-informed individual specific modelling of brain networks.\n\n*Abstract:*
  The human brain is a system of networks\, each underlying a specific func
 tion\, and interacting with each other. Brain networks at rest\; also know
 n as resting state networks (RSNs)\, have been very influential in charact
 erisation of the functional organisation of the brain. The framework of Pr
 obabilistic Functional Modes (PROFUMO) is designed to estimate RSNs simult
 aneously for populations and every individual therein\, thus permitting us
  to capture individual-specific characteristics beyond what has been possi
 ble using standard group-average-based techniques such as ICA. In this tal
 k\, I will first describe this modelling framework and its various extensi
 ons. I will then show some of its applications to large fMRI datasets such
  as the Human Connectome Project and UK Biobank\, including the characteri
 sation of multiscale brain modes\, prediction of non-imaging traits\, and 
 potential for subgroup discovery. \n\n*Bio:* Rezvan Farahibozorg is a Roya
 l Academy of Engineering research fellow at FMRIB\, Oxford. Her research a
 ims to design new machine learning tools for big functional brain imaging 
 data such as UK Biobank\, and to make predictions about personalised trait
 s (e.g. age or cognitive scores) and disease (e.g. Dementia). Before joini
 ng FMRIB\, she was trained as a Biomedical Engineer and proceeded to compl
 ete her PhD at CBU\, working on developing brain connectivity methods for 
 magnetoencephalography\, and application for characterising semantic netwo
 rks in the brain.\n\n*Venue:* MRC CBU West Wing Seminar Room and Zoom http
