ABSTRACT
The author believes the analysis of cluster evolution provides a promising and challenging
research agenda in EEG for the years to come.
An earlier version of this paper has been presented at the Regional Studies Association
European Conference, Tampere, 2013. I have benefited from the useful comments made
by the participants of this event and particularly by three anonymous reviewers. I would
like to thank the interviewees for sparing their time. The usual disclaimer applies,
however.
