Blood flow in the human cerebral cortex: Large-scale pial vascularization and 1D simulation
Fig 6
Hemodynamics in the cerebral cortex for the normotensive scenario.
Flow rate is reported in logarithmic scale. Top panel: Distribution of mean blood pressure over time , mean flow rate over time
, and their joint kernel density estimate distribution in the pial networks for each of the three territories
(red),
(green), and
(blue), and also for the entire pial network
(gray). Mid panel: Pressure (top left inset) and flow rate (top right inset) waveforms along four evenly spaced locations placed in three arbitrarily chosen paths with length L (one per territory); pressure through space is characterized in the space-time domain (bottom left inset, isolines in white), and using the maximum, mean and minimum temporal values of the pressure waveforms along each path (bottom right inset) from the corresponding territory root to the terminal point at distance L. Bottom panel: Visualization of the blood pressure in each vessel along the entire cortex network for five different time-instants during the cardiac cycle.
