Brain Function and Blood Flow Regulation

The video discusses the brain's critical need for a constant supply of oxygen and glucose, which is essential for its function. It highlights the importance of balanced blood flow to prevent damage and maintain brain health. The concept of cerebral blood flow autoregulation is introduced, explaining how the brain maintains constant blood flow despite changes in arterial pressure. Research led by David Harder at the Medical College of Wisconsin focuses on understanding the mechanisms of blood flow autoregulation, with aims to improve treatments for neurological conditions.

What percentage of the body's glucose does the brain use?

• 25%

• 50%

• 10%
