Hi Adam,
Language activations definitely hit Default B, but Default B is also activated by tasks such as theory of mind (see Figure 4 here: https://www.biorxiv.org/content/biorxiv/early/2017/06/19/149567.full.pdf), so I am not sure we can consider it to be a pure language network.
Although there has been papers trying to delineate language networks using resting-state fMRI, my experience is that it's not something that easily pops out of resting-state data, compared with task or meta-analytic data (e.g., see component 5 here: http://people.csail.mit.edu/ythomas/publications/2015BrainmapInteractive/ind... )

Hi Dr. Yeo,
Just a related question -- do you have an opinion on if one of the network solutions corresponds to the language network? I realize they are all bilateral, with no significantly left lateralized one. But do you think one of the DMN solutions (such as Default B in the paper you linked, much more representative on the LH surface view) might represent the language network?

Hi Chintan,
Sorry. At that time, we wanted to not bias the interpretation of the networks by naming them. But that may be a bit idealistic. We have subsequently named the networks.
To map networks 1 to 17 to the names, the easiest way is to load the annot in freeview and hover your mouse over it and then visually match it to Figure 1 of this paper (http://people.csail.mit.edu/y thomas/publications/2015SleepDeprivation-NeuroImage.pdf). When I do so, I get the following, but you probably want to double check!
Network 1: Visual A
Network 2: Visual B
Network 3: SomMot A
Network 4: SomMot B
Network 5: DorsAttn A
Network 6: DorsAttn B
Network 7: Sal/VentAttn A
Network 8: Sal/VentAttn B
Network 9: Limbic B
Network 10: Limbic A
Network 11: Control C
Network 12: Control A
Network 13: Control B
Network 14: TempPar
Network 15: Default C
Network 16: Default A
Network 17: Default B

Dear Freesurfer users,
I am examining the Yeo 2011 17 Network atlases in Freesurfer 6.0. The regions are labeled 1 through 17. Is there a reference table mapping these numbers with the names of cognitive networks described by Yeo, et al. (2011) ( https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3174820/ https://www.ncbi.nlm.nih.gov/pubmed/21653723)? For example, would network 1 correspond to visual networks? I cannot find descriptions in the readme files except the color look-up table.
Thank you.
Best,
Chintan
