secondary reasurch sorce

i read bout a boy that was mexican who knew spanish, and was talking bout scientist that have diveloped technoligy that can read a persons brain and see what languages they know, and what they speak. he was also talking bout how they count read their inds and coouldnt see what they were thinking in and what language they were thinking in. iots something uknown, unexpected to hear/see in the person. basicly to say, my reasults wont have a solid answer, its not a yes or no question, it has to do with the person. Where and how they grew up speaking a cretin language. This makes me interested in my data and makes me wonder how these kids grew up.
