Abstract

The human brain depends on adequate oxygen more than any other part of the body. These visualizations illustrate the regulation and consumption of oxygen in the brain. These biological processes were analyzed using fMRI and plotted into topographic maps with original software.

When a brain area is active there is a higher demand for oxygen and the local response is an increase in blood flow to these active regions. Using functional magnetic resonance imaging (fMRI), the brain activity of 6 persons (3 adults resting quietly with their eyes closed and 3 adults breathing slowly) was analyzed. Images of the oxygen extraction fraction (OEF) showed the different variations of oxygen extracted by the brain from arterial blood. Then, these images were processed and transformed into topographic maps.
