SPECT Functional Brain Imaging Is Not 'Mind Reading'

In an interesting report on functional brain imaging Lesley Stahl graphically demonstrates [excellent video footage] some of the exciting progress with the actual brain ' pictures of thinking' - thinking about specific items: hammer, screwdriver etc. Dr Just at Carnegie Mellon is one of the interviewees - in this short report they put a 60 Minutes producer in the fMRI machine, took pictures of her brain activity, then demonstrated exactly what she was thinking whilst in the machine. Good Stuff!
With fMRI and SPECT the essential key word here is "functional" brain imaging - this MRI photo >> is simply an example of a static MRI picture, not functioning, not actually thinking in process, just anatomic structure. The ' brain action' is in the ' function.'
In the comments that follow on the CBS site one can easily see how the ' Mind Reading' spin clearly terrified some folks, as the researchers indicated that we would soon have beams bouncing off our heads that would know our private thoughts. Not to worry, the benefit outweighs the risk - and the hype does a disservice to the message.
