Reduced cerebral blood flow does not alter concurrent or post-intervention inhibitory control: evidence from a 3-h head-down tilt protocol in healthy young adults

Key Points

• Cerebral blood flow alteration during head-down tilt showed no change in inhibitory control.
• Inhibitory control remained consistent despite significant changes in cerebral blood flow over the 3-hour protocol.
• Assessment using a head-down tilt protocol engaged physiological responses without affecting cognitive performance.
• These findings highlight potential neurovascular mechanisms that maintain inhibitory control even when blood flow changes.
