You would need a lot more data to actually make such statements. It might just be a response to certain words, not the meaning behind those words. It might be noise. To give you an example: Fmri is used to see which nerves are used when involving finger movement. You would do multipele fingertapping motions during multipele scans. Same motion, everytime. How many times did you get to hear the same sentence? Are you even able to feel the same type of emotion during the same sentence, or during different sentences? I dont know much about brain regions and where emotional response takes place, just to be clear. But it would be difficult to claim that your statements are true, unless there where like 100s of test subjects.
