Researchers found algorithm errors in the commonly used special software for functional magnetic resonance imaging (fMRI)  They collected the examination results of 499 healthy people in a resting state and found that their statistical methods need to be verified by real cases  This means that the software can sometimes be ridiculously wrong  Even when the brain is still, the software shows activity of people
At present, the false positive rate of fMRI software which is commonly used to diagnose brain function has increased.
 The activity shown by software is the product of software algorithms, not that the studied brain is really in an active state
