(Nature) – The approach is based on burgeoning research that uses fMRI to understand the nature of pain — a very subjective experience. Scientists hope that the scans can provide an objective measure of that experience, and they see potential applications, such as in testing painkillers. But many neuroscientists say that the techniques are still far from being accurate enough for the courtroom. Critics say that the companies using them have not validated their tests or proved that they are impervious to deception or bias. And whereas some think the technologies will have a place in legal settings, others worry that the practice will lead to misuse of the scans.
