VR Pupillometry Tracked Working Memory Load: Clinical Cohorts Had Smaller 2-Back Responses
TL;DR: A 2026 medRxiv preprint found that pupil dilation measured inside a virtual reality (VR) headset increased as working-memory load rose in healthy adults, was reproducible 60–90 days later in 33 returnees, and was smaller under the highest load in cognit…
