Cerebral Blood Flow Response to Vestibular Stimulation. Response of subjects to five frequencies of stimulation averaged over 40 cycles for 0.5 Hz, 20 cycles for 0.25 Hz, 10 cycles of 0.125 Hz, and 5 cycles of 0.0625 Hz and 0.03125 Hz. Cerebral flow velocity (CFV) in the middle cerebral artery was affected at all frequencies during sinusoidal translation in the pitch plane (providing a pitch tilt stimulus) while being rotated at 250 deg/sec (CEN - Centrifugation) as well as sinusoidal ± 25 degree pitch tilt (TILT). Base represents mean of 3 min baseline while sitting quietly in both conditions and Rot represents three minute average while rotating on center during centrifugation.
