The poster you responding to is correct to a large extent. Yes, you can record waves, and you can even classify them like N170. Responses can be 'localized'; however, one has to be a bit careful. Even many researchers say it is new phrenology: for instance, William R. Uttal wrote a book on it, called "The New Phrenology. The limits of localizing cognitive processes in the Brain". This book is not based on philosophical arguments, but based on the research done by cognitive neuroscientists. I am yet to come across a substantial criticism against Uttal's book. Just because localization is at most one can do, it is not cure to solve all puzzles/problems.
