Vagal Afferent Signalling and Cognitive State; Cognitive neuroscience; Neurofeedback; Evidence synthesis; Research methodologyAbstract
There is real interest in vagal afferent signalling and cognitive state right now, and real uncertainty about exactly where it
delivers the most value. We pull together the current evidence for vagal afferent signalling and cognitive state, 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.
