Capsulotomy in 23 post-surgery OCD patients is linked to greater post-error flexibility toward ID versus ED shifting on the EDID task, despite more ED errors.
- Why it matters: OCD involves widespread executive deficits tied to frontostriatal disruption, but how capsulotomy alters specific executive neural substrates is unclear.
- What they did: The study tested set-shifting (EDID) and working memory (N-back) with task-based fMRI, and conflict processing (Flanker) behaviorally, comparing post-capsulotomy OCD, OCD controls, and healthy controls.
- The result: Capsulotomy was associated with decreased pre-supplementary motor area activity to ED shifts versus healthy controls, while no capsulotomy effects emerged for N-back or Flanker; OCD groups showed persistent working-memory and conflict-processing dysfunction.
