Abstract

There is real interest in sample size and effect size in task-based functional imaging right now, and real uncertainty about exactly
where it delivers the most value. We pull together the current evidence for sample size and effect size in task-based functional
imaging, covering the methodological, practical, regulatory and cost angles, with an eye on where practice has genuinely settled
and where researchers and reviewers are still largely working it out for themselves. Selective, context-specific pursuit looks better
supported by the evidence gathered here than either broad rollout or blanket avoidance.
