Dear MEGCommunity colleagues: This email is to inform you of an open call to submit contributions to a research topic in Frontiers in Human Neuroscience that I have the pleasure to edit. The research topic is entitled "It's about time! Characterizing Time-varying Complex Brain Networks". The deadline for abstracts submission is January 31st, 2015. Submissions are welcome, which explore the dynamical aspects of functional and effective brain connectivity at different time scales (from sub-seconds in MEG/EEG or LFP to seconds, minutes or beyond with these same techniques in fMRI) by applying the paradigm of temporal and adaptive networks, and the role of this dynamics in normal and pathological brain function. For details on the research topic including a complete description as well as submission of abstracts / papers, please visit the topic's website at: http://journal.frontiersin.org/ResearchTopic/2712 Looking forward to your contributions Sincerely Ernesto Pereda, Ph.
