Host PI :  Kenji Leibnitz


Recent advancements in measurement and analysis of resting-state fMRI data allow tracking fluctuations in human brain functional connectivity on a time scale of tens of seconds. Fluctuations in functional connectivity were studied mainly at the individual edge level in the beginning, while global network-level fluctuations in functional connectivity have received more attention nowadays, because of recent reports on their potential relation to behavior and cognition. In this seminar, I will talk about studies on characterizing the spatial patterning of these global network-level connectivity fluctuations, which I worked on when I was in Indiana University. In particular, global fluctuating patterns regarding to the relationship between task-positive and task-negative systems and the relationship between structural connectivity and functional connectivity will be presented. Finally I will briefly introduce a follow-up modeling study that examines the reproducibility of these global fluctuations observed in empirical data.

About CiNet's Friday Lunch Seminars:
The Friday Lunch Seminar is CiNet's main regular meeting series, held every week at 12:15 in the beautiful main lecture theatre on the ground floor at CiNet. The talks are typically 40mins long and orientated towards an inter-disciplinary audience. They are informal, social, and most people bring their own lunch to eat during the talk. They are open to anyone who is feeling curious and wants to come, regardless of where you work.
