If the study posted previously about fMRI being able to peer into your mind and determine not only if you are experiencing pain, but how much pain you are experiencing didn’t give you pause, these reports should.
Researchers are developing techniques using fMRI to see what you are thinking, or who you are thinking about. Soon it will be possible to read your mind, see your dreams and see what you are feeling. MRI technology is increasing in speed every day. Soon it may be possible to acquire one when you walk through a doorway. No longer will you have to lie still in a magnet for an hour.
