While N170 is a common marker in ERP literature of face processing. What I am really interested is visual processing of faces through time and brain regions. I am interested where brain activates prior, during, and after N170 or other ERPs.

<p>I am looking for references where people were able to collect 128-256 channel EEG data during face perception task and the map it onto FFA or OFA using source localization algorithms?</p>

Are there any studies that were able to localize Fusiform Face Area (FFA) for face processing using EEG source localization algorithms?

The N170 (the face selective component of the brain) is commonly mapped indeed to OFA or FFA. It's trivial to find examples for this, e.g.: [this](http://www.ncbi.nlm.nih.gov/pubmed/24185024), [this](http://www.oxfordhandbooks.com/view/10.1093/oxfordhb/9780199559053.001.0001/oxfordhb-9780199559053-e-017), [this](http://jov.arvojournals.org/article.aspx?articleid=2138698), [this](http://jov.arvojournals.org/article.aspx?articleid=2137096), [this](http://cerco.ups-tlse.fr/pdf0609/itier_rj_04_1261.pdf).
