Scientists have been able to revive dead brains in the laboratory after injecting them with a type of simple plants spread in most of the water swamps, rivers and streams around the world.
Scientists injected green algae and cyanobacteria into the brains of African clawed frogs (Xenopus laevis), and these simple plants were able to breathe life back into the oxygen-starved neurons of tadpoles similar to what happens when performing internal cardiopulmonary resuscitation.
Measurements inside the tadpoles' brains showed an increase in local oxygen when green algae or cyanobacteria were present, through the process of photosynthesis.
The scientists observed that when the frogs were denied oxygen, even within their neurons, the microorganisms in their brains were able to reactivate the neurons, saving them from the brink.
Microalgae, which are simple plants, possess special types of micro-bacteria that are capable of producing huge amounts of oxygen in the atmosphere; Scientists believe that algae is the main reason why our planet first had oxygenated air millions of years ago.
The authors suggest injecting the microorganisms into the cardiovascular system rather than into the brain; Because these microorganisms when they flow into the veins and arteries under the skin will receive more sunlight.
But the scientific team has concerns that this concept is "too innovative" and could be harmful, especially if these microorganisms spiral out of control inside the human body. It can block blood vessels, and cause death.
And neuroscientist Diana Martinez warned, in statements to The Scientist, that if "too much oxygen is produced, it may be as dangerous as oxygen deprivation."
The inability to properly control oxygen levels through the use of photosynthetic organisms is as harmful as hypoxia itself."
