The Journal of Physiology, Volume 604, Issue 5, Page 2336-2354, 1 March 2026.Abstract figure legend Hypocapnic hyperventilation reduced end‐tidal carbon dioxide partial pressure and middle cerebral artery mean velocity, and impaired oculomotor response by modulating visual fixation and anti‐saccadic control. Hyperventilation itself also impaired anti‐saccadic control.
