Why Brain Activity Doesn’t Reveal Our Minds
There is poor correlation between different scans of even the same person’s brain, experienced researchers sayAt one time, we were told that, one day, machines will read our minds. But, now researchers say, the more we know about the brain (set aside the mind for a moment), the more reasons we have for doubt: But a new analysis by some of the researchers who have done the most work in this area finds that those measurements are highly suspect when it comes to drawing conclusions about any individual person’s brain. Karl Leif Bates, “Studies of brain activity aren’t as useful as scientists thought” at Duke Today Brain scanning—functional MRI (fMRI)—tells us about general brain structures, says Duke University neuroscientist Ahmad Hariri, who led a team that reanalyzed the data. It doesn’t say much about the…
