Scans of people with opioid use disorder watching Trainspotting, before and after eight weeks of added treatment, identified a frontal activity pattern associated with treatment. A separate group then watched the same film with real feedback on how closely their brain activity matched that pattern, or with sham feedback. Real feedback improved the match and reduced craving; no sample sizes or effect sizes are given.
Why it is interesting: An early test of aligning one patient's brain activity with a peer's, with craving the outcome.
