Gender characteristics of cerebral hemodynamics during complex cognitive functioning


Misteli, M; Duschek, S; Richter, A; Grimm, S; Rezk, M; Kraehenmann, R; Boeker, H; Seifritz, E; Schuepbach, D (2011). Gender characteristics of cerebral hemodynamics during complex cognitive functioning. Brain and Cognition, 76(1):123-130.

Abstract

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