How does thinking work in the brain?
In order for your brain to think, you need nerve cells that can detect information about the outside world and can transmit that information to other nerve cells. It’s the transmission of information, the cells talking to each other, that’s the fundamental physical basis for how thinking works.
Do humans have 4 brains?
Yes, you have four brains. Advances in medical technology have allowed scientists to peek inside humans like never before. And they found four brains.
Do brain cells come back?
Summary: When adult brain cells are injured, they revert to an embryonic state, say researchers. In their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
Can a person still hear after they die?
Now UBC researchers have evidence that some people may still be able to hear while in an unresponsive state at the end of their life. This research, published recently in Scientific Reports, is the first to investigate hearing in humans when they are close to death.
What stops working first when dying?
When someone is dying, their heartbeat and blood circulation slow down. The brain and organs receive less oxygen than they need and so work less well. In the days before death, people often begin to lose control of their breathing. It’s common for people to be very calm in the hours before they die.
