The recent meeting at Harvard on neuroimaging, pain, and the law demonstrated powerfully that the offering of neuroimaging as evidence of pain, in court and in administrative hearings, is growing closer. The science for identifying a likely pattern of neuroimaging results strongly associated with the subjective sensation of pain keeps improving. Two companies (and here) recently were founded to provide electro-encephalography (EEG) evidence of the existence of pain. And at least one neuroscientist has been providing expert testimony that a particular neuroimaging signal detected using functional magnetic resonance imaging (fMRI) is useful evidence of the existence of pain, as discussed recently in Nature.
If nothing more is done, neuroimaging evidence of pain will be offered, accepted, rejected, relied upon, and discounted in the normal, chaotic course of the law’s evolution. A “good” result, permitting appropriate use of some valid neuroimaging evidence and rejecting inappropriate use of other such evidence, might come about. Or it might not.
We can do better than this existing non-system. And the time to start planning a better approach is now. (Read on for more on how)
