Exactly how long does the brain stay active after death?

Even after death, the human brain remains active for a while.However, when the heart stops beating,someone is considered dead. When respiration and blood flow stop,our body immediately becomes paralyzed.But even if the heart is immobile, the flow of electricity to the brain continues for some time after

death. Rather, the brain is the only organ in the body that is inactive after all.The largest part of the brain is called the cerebral cortex. This is the part that makes people think and make decisions.The cerebral cortex is active for 2 to 20 seconds without oxygen.That is, even after death,the human brain remains awake at this time.After death, all the self and muscular powers become inactive, but this is the time when the brain begins to feel its last moments of oxygen.

During this time the brain cells secrete chemicals for the last time which leads them towards their last moment.

Just when someone is able to turn on your heart through CPR for life support, your brain will begin to receive enough oxygen to work again.However, in the absence of oxygen, the brain also slowly begins to surrender.Within a short time, most of the brain begins to die.However, even at the last moment, a part does not want to accept the rate easily.And that is the memory centre.

At this time the most sensitive memories of the laughter and tears of the dead person's life floated before his eyes.That is the latest reaction of the brain.At the same time, the last part of the body also becomes silent.Scientists can scan and collect data from the brains of some clinically dead patients after their life support has been cut off, and find that their brains remained active for more than 10 minutes after death.That means their feelings were active for about 10 minutes.  But do you know the most important information!!Everyone's recorded information was different from each other.That is, everyone's feelings of death are different from each other.
