Can We Keep Neurons Active…with Algae?

The video discusses the role of photosynthesis in oxygen production and its potential use in reactivating oxygen-starved neurons. Researchers in Germany are experimenting with microbes like green algae and cyanobacteria to deliver oxygen to the brain. The study used Xenopus tadpoles to test this concept, but challenges remain, such as immune responses and the risk of artery blockage. While human application is far off, alternative technologies like gas-filled microparticles offer potential solutions for oxygen deprivation.

What organisms are being studied for their ability to produce oxygen through photosynthesis?

• Green algae and cyanobacteria

• Mushrooms and fungi

• Insects and arachnids

• Bacteria and viruses

In the experiment with Xenopus tadpoles, where were the microbes injected?

• Into the lungs

• Into the liver

• Into the heart

• Into the brain

What is a potential risk of using microbes to deliver oxygen in humans?

• Microbes could cause excessive oxygen production

• Microbes could increase blood pressure

• Microbes might enhance immune response

• Microbes might clog arteries

Why is it challenging to apply this research to humans?

• Humans have transparent skin

• Humans are similar to tadpoles

• Humans have opaque skin and complex immune systems

• Microbes are easy to control in humans

What alternative technology is mentioned for addressing oxygen deprivation in humans?

• Administering herbal supplements

• Applying heat therapy

• Using electric shocks

• Injecting gas-filled microparticles
