This Is Your Brain on GPS

The video discusses a new rapid blood type test developed by Chinese researchers, which can determine blood type in 30 seconds using a paper-based method. This test could be crucial for emergency transfusions. It contrasts traditional blood testing methods with the innovative paper test. Additionally, the video explores a study on brain activity during navigation, highlighting the role of the hippocampus in spatial memory and learning, especially when navigating without GPS assistance.

What determines your blood type according to the new rapid test?

• The amount of plasma in your blood

• The color of your blood

• The speed of blood flow

• The type of antigens on your red blood cells

How does the paper-based blood test indicate blood type?

• By measuring the temperature of the blood

• By analyzing the DNA in the blood

• By counting the number of red blood cells

• By using a dye that changes color

What is the accuracy rate of the new paper-based blood test?

• 97.5%

• 99.9%

• 100%

• 95%

Which part of the brain is involved in navigation and spatial memory?

• Cerebellum

• Hippocampus

• Frontal lobe

• Occipital lobe

What was observed in the brains of London taxi drivers after passing their navigation test?

• Increased activity in the cerebellum

• Decreased brain tissue in the hippocampus

• No change in brain structure

• Increased brain tissue in the hippocampus
