Surprise! Your Brain Has a Secret Sewer System

The video explores the discovery and function of the glymphatic system, a hidden network in the brain responsible for clearing waste, primarily during sleep. It highlights the system's role in preventing diseases and its implications for understanding brain health. The video also discusses recent discoveries of lymphatic vessels in the brain and the potential impact on treating neurodegenerative diseases. Despite advancements, much remains to be learned about these systems and their interactions.

What is the primary function of the glymphatic system in the brain?

• To clear away waste

• To produce cerebrospinal fluid

• To transmit nerve signals

• To regulate blood flow

Which technique was used to discover the glymphatic system?

• MRI scanning

• Ultrasound

• X-ray imaging

• Two-photon microscopy

When is the glymphatic system most active?

• When you are awake

• During physical exercise

• When you are eating

• While you are sleeping

What potential role does the glymphatic system play in neurodegenerative diseases?

• It increases the production of large proteins

• It helps clear away protein buildups

• It causes the brain to shrink

• It enhances memory retention

Where were the unexpected lymphatic vessels found in the human brain?

• In the cerebellum

• In the meninges

• In the hippocampus

• In the frontal lobe
