The decline in cognition observed in obstructive sleep apnea is linked to intermittent hypercapnic hypoxia (IHH), which is known to impair cerebrovascular reactivity. Whether acute IHH impairs the matching of cerebral blood flow to metabolism (i.e., neurovascular coupling, NVC) is unknown. We hypothesized that acute IHH would reduce cerebral NVC. Healthy participants (N = 17, 8 females, 9 males; age 22 ± 3 years) had cerebral NVC measured at baseline and following 40-min of IHH at 1-min cycles with 40-s of hypercapnic hyp
