Dear colleagues: We are organizing the second International Conference on Resting State Connectivity in Milwaukee, Wisconsin, from September 17–19, 2010. This meeting aims to bring together key researchers working on the physiological background, application, and analysis of resting-state functional connectivity data in a very congenial and highly interactive setting. Thus, the number of attendees will be restricted in order to ensure priority to communication on a highly professional level instead of promotion or introduction of the phenomenon. During our three-day schedule, we will focus on the physical, physiological, statistical, and psychological implications of R‑fMRI and use this forum to define future directions in R-fMRI research. We have assembled an impressive list of speakers (that continues to increase). We look forward to you joining us. More details, including registration information and abstract submission, can be found at: http://www.restingstate.com/ Invited speakers include: Peter Bandettini, NIMH/NIH Habib Benali, Université Pierre et Marie Curie Rasmus Birn, University of Wisconsin–Madison Bharat Biswal, UMDNJ–New Jersey Medical School Melanie Boly, University of Liège Michael Breakspear, Royal Brisbane Hospital F.
