Temporal fMRI Dynamics Map Dopamine Physiology

2025-03-26

Abstract excerpt

<h4>ABSTRACT</h4> Spatial variations in dopamine function are linked to cognition and substance use disorders but are challenging to characterize with current methods. Because dopamine influences blood vessel dilation, we hypothesized that hemodynamic latency, which reflects BOLD signal timing, could serve as an indirect marker of dopamine physiology. Across four datasets, we found a topography of hemodynamic lat...
