Does hypnotizability affect neurovascular coupling during cognitive tasks?

•Scales identify low-to-medium (LM) and medium-to-high (MH) hypnotizable subjects.•Cerebral oxygenation (TOI) was measured during cognitive tasks in LM and MH.•TOI time course during mental computation was different in LM and MH.•Only MH showed different increases in TOI during different cognitive tasks.•Hypnotizability affects the magnitude and time course of functional hyperemia.
