The brain cannot be transplanted, or at least not yet, it is the center of operations of our organization, and from there are many of the conscious and unconscious functions that we perform, however, recent studies have begun to question whether the brain can take its own life after stopping the activity of the body. After all, can the brain be resurrected?
A survey by laboratories in Berlin and several U. S. centers studied neuron activity in people with irreversible brain damage and those who had suffered a respiratory outage moments earlier.
- In other words.
- They were clinically dead people.
- Scientists have observed that.
- Unsurprisingly.
- Neurons have stopped working because of lack of oxygen.
However, the surprising thing was to observe that even without oxygen, the neurons maintained some activity (called scattering depolarization) that lasted for a similar time without causing irreversible damage to the neurons, later they entered a critical situation in which the damage was became irreversible.
This indicates that neurons maintain their survival even in the absence of oxygen for a very long period of time, although electroencephalogram records show no signs of brain activity and the heart shuts down forever.
This information invites us to think about the limits of life after death.
New research published in the journal Nature has managed to keep the brains of pigs out of their bodies alive. Researchers extracted and isolated the brains from slaughtered pigs and, after four hours out of the body, placed them in a system that allowed them to maintain nutrients. oxygen through the blood vessels of the brain.
Six hours after this action, they observed that neurons regained their metabolic functions, consumed sugar and the immune system began to function again.
Later, they even managed to electrically stimulate neurons and regained their ability to communicate with each other.
Would it be possible to resurrect the brain after a cardiopulmonary stop and, indirectly, regain body activity?
A fascinating aspect was to note that the behavior of neurons in the brain was not simultaneous, which would be an indication that neurons acted autonomously regardless of selective stimuli, i. e. the recovery of a certain “Consciousness”.
The researchers stopped brain activity by performing six hours for ethical reasons, their intention was not to achieve a resurrection of consciousness, but to achieve a complex study model in which they could analyze the effects of drugs and other treatments on brain activity.
However, these events have provoked a debate about the starting point of consciousness after the death of the individual. In most countries, a person is considered legally dead when their heart and lung activity ceases.
The brain needs a considerable amount of oxygen, blood and energy, so its resurrection is considered unattainable until now.
Would it be possible to resurrect the brain after a cardiopulmonary stop and indirectly regain body activity?Are there more opportunities to figure out how to perform brain transplants in the future?Are these fascinating questions open to debate?
