Key result
High-effective cognitive performance in young men was associated with shorter rheographic wave propagation time, longer slow blood filling time, and higher rheographic index asymmetry compared to low-effective performance.
Population
42 practically healthy young men, mean age 19.40 ± 1.20 years.
Comparison
Modeled purposeful cognitive activity vs Initial condition of relative physiological rest
Design
Cross-sectional

Observed hemodynamic differences may relate to cognitive effectiveness in healthy young men; leaves open causal mechanisms and clinical relevance.
Cross-Sectional (n=42)
No
Physiological support of cognitive tasks varies based on task effectiveness, reflected in different brain hemodynamics and autonomic regulatory activity.
Kulagin et al. (2023) conducted a cross-sectional in Healthy (n=42). High-effective cognitive performance vs. Low-effective cognitive performance was evaluated on Rheoencephalographic and heart rhythm variability parameters during cognitive activity. High-effective cognitive performance in young men was associated with shorter rheographic wave propagation time, longer slow blood filling time, and higher rheographic index asymmetry compared to low-effective performance.
