Key Points

  • To examine how biological sex impacts dynamic cerebral autoregulation and its directional sensitivity.
  • Assessed dynamic cerebral autoregulation in males and females during physiological stress.
  • Measured directional sensitivity at a frequency of ~0.10 Hz OLBNP in participants.
  • Females demonstrated superior dynamic cerebral autoregulation compared to males.
  • Females displayed greater directional sensitivity at ~0.10 Hz OLBNP.

Abstract

in females only. These findings indicate that females exhibit better dCA and greater directional sensitivity at 0.10 Hz OLBNP.
