Today I have a very intresting blogs. It took me 3-4 days just to gather the information about it. So, make sure to read it till last.
*After we die, our brain continue to work for more than 10 minutes. Our current understanding of death is very simple. We considered people dead the moment their hearts stop working. The respiratory and circulatory systems are no longer functioning. The body just shut down and life ceases to be. but there is more to it than that, Despite having a functionally dead heart, our brain continue to work. In fact, it might be the last part of your body to die.*
Moments before death, our brain receives a surge of electricity. No one knows why it happens. It also begins to lose oxygen. Even after we are breathing and heart beat stop, we are still conscious for about 2-20 seconds. This is because the cerebral cortex can last without oxygen. This part of brain is responsible for thinking and decision making. It is also responsible for converting the information gather by our senses into actions. Despite this activity in cerebral cortex, you lose all reflexive and muscular ability before death. At this moment, the brain is experiencing its last moments, Brain cells are activating chemical pathways that would lead to their ultimate death.
A pump of oxygen is what stand between us and our final moment. If someone manages to restart our heart through CPR or life support, Our brain will receive enough oxygen to wake up again. If there is no oxygen, our brain begins to surrender. Most of our brain is dead now,but there is one final place that does not give up so easily.This is the memory center, which store the most emotional memories we've ever experience.
This region in our brain is not susceptible to blood loss even during serious injuries and it is the last part of our brain to shut down. before shutting down the memory center flashes moments from our life right before our eyes.
When doctors turned off life support for terminal patient is declared clinically dead. The brain appeared to be active for more than 10 minutes. And when they scanned electroencephalographic (EEG) recording in these individuals, they found striking differences between each one of them. this probably means that every one of us will go through a unique experience when we die. 2 days after death, more than 1000 genes are still working in the body. Some of these genes are highly active, and they have very important functions.
pic of genes
Stimulating inflammation, firing up the immune system and counteracting stress but some of these genes are only switched on during embryonic development. Is it possible that the body is trying to save itself from imminent death by reverting to a cellular stage? some of these, however, promote cancer growth. Why would the body initiate cancer growth even 2 days after death? What is the purpose of promoting cancer in a dead body? MYSTERIOUS INDEED!!!!
It is possible that our understanding of death is false.Is it ethical to pronounce people dead when some part of their body are still working? And what does this mean for those whose organs are donated immediately after death? should we be more careful when conducting autopsies on dead bodies?*
Only more time and more research will reveal this to us. *
