摘要: Functional Transcranial Doppler sonography (fTCD) has been applied to assess peak mean cerebral blood flow velocity (MFV) with a high temporal resolution during cognitive activation. Yet, little attention devoted gender-related alterations of MFV, including spectral analysis. In healthy subjects, fTCD was used investigate series hemodynamic parameters in the middle arteries (MCA) Trail Making Tests (TMT), means selective and complex functioning. females, there frequency at 0.375 Hz both MCA, we observed dynamic shift hemispheric dominance that condition. Further, after start phase, an MFV decline functioning for entire sample. These novel results suggest condition-specific features hemodynamics it adds notion gender is fundamental confounder brain physiology.
