Can someone inform me very briefly (or indicating the reference) about symmetries, sides or lateralization of default mode network (DMN) in human brain?
there were some papers published recently (one very new, one a bit older) that might help you:
1. Agcaoglu O, Miller R, Mayer AR, Hugdahl K, Calhoun VD.: Lateralization of resting state networks and relationship to age and gender. NeuroImage. 2015 Jan;104:310-25. doi: 10.1016/j.neuroimage.2014.09.001. Epub 2014 Sep 18.
2. Saenger VM, Barrios FA, Martínez-Gudiño ML, Alcauter S.: Hemispheric asymmetries of functional connectivity and grey matter volume in the default mode network. Neuropsychologia. 2012 Jun;50(7):1308-15. doi: 10.1016/j.neuropsychologia.2012.02.014. Epub 2012 Mar 1.
