Can your brain detect that your body is dead and that it needs to be revived or your brain will die?

interesting question. I'm not sure I think it would depend on how you die. If it was something that would affect your brain like spine injury or stroke probly not but maybe if you have a heart attack your brain can still process for a few seconds while it still has blood that your heart stopped and you are dying. I do know that the brain can still work when cut off from the body (for a few seconds.) When they decapitated people they told them to blink until they couldn't anymore and the people would blink for almost 30 seconds after the head was cut off until they bleed to death. Kinda scary...

It all depends if your brain is still alive , you would be dreaming intermittently...if the brain is dead then you would just be kept from moving on until your body die. If you know what's going on around you, then I think it would be awful but never been in that position. That's why is so important to fill a living will when you are going to be admitted in to a hospital. You could also let someone close to you know what would you like to do in that case.

Nerves stimulate areas of the brain that correspond to the part of the body they connect with.  The part may be gone, but the brain area isn't and can be stimulated by the remainder of the nerves, other brain areas, or just become slightly active.  The brain doesn't know the part is gone and anytime that area is stimulated you feel the body part even if it isn't there due to amputation.

one would know once they're near death

The brain starts slowing down first, and it tells the heart to slow down too. so technically, the brain quits first and when the heart stops recieving messages to beat, it stops too.

nope, breathing is part of the autonomic system, your brain will make you breathe, and if you aren't getting enough oxygen, it will wake you up and make you find oxygen by uncovering yourself.

Your body will go into starvation mode and start to shut down.  Your body will retain all it's energy for making your brain and heart work, but at some point those would shut down, too.

Have you not hear people asking HAVE YOU LOST YOUR BRAIN MIND YOUR OWN BUSINESS \nSO YOU SEE THE DIFFERENCE\nPEOPLE WHO LOSE CONSCIOUSNESS HAVE BRAIN BUT THEIR MIND STOPPED WORKING.\nBRAIN IS LOCATED IN HEAD BUT MIND IS REALATED TO HEART TOO

after about 4-5 minutes your brain starts to die, you heart will probably stop soon after that. Less then 10 minutes and you're pretty much dead

Your heart stops beating.  Your synapses slow their firing until you are brain dead and no electrical current is flowing through the nervous system.  Your body will generally expel any waste matter (air, urine, feces) being held.  Sometime around this time, you will either discover that there is an afterlife of some sort, or you will blink into nothingness, with absolutely no consciousness to be aware of the fact that there is no afterlife.  The body will begin the approach to rigor mortise.  And bacteria will begin decomposing the body.  Years and years later, only ash (and perhaps fossilized bones) will be left of your body.  If there is an afterlife, you will never be able to tell anyone.  If there isn't, you will never be able to tell anyone.  Those who say they know the truth about the afterlife, either way, are not intellectually honest.  Which is why this question will continue to evoke philosophical debate ad infinitum.

Nah, that is really hard to tell.\nIf you feel like you are going to die in an automobile accident, you certainly will.\n"What the mind can percieve, the body can achieve."\nLOL\nYou have to be careful all the time.

yes, when brain activity ceases the body releases your muscles used to keep things inside.

As far as pronouncing a human dead they must fulfill certain requirements:\n-Response to pain – a highly scientific object, such as a key is pressed down onto the thumbnail very hard, someone living should react.  In this test we are looking for brain activity.\n-Pupil response to light – a light is directed into the pupil of the eye (both left and right), the pupil should contract if the person is living.  Again this test is looking for brain function.\n-A heartbeat and pulse.\n-Signs of breathing.\nIf a presumed dead person has no response to pain, no response to light, no evidence of a heartbeat or pulse, and no signs of breathing, the person is considered dead.  If the person does not meat one of these they are considered alive.\n\nFrom a pure biological standpoint this is a far more difficult question however.  Take a tree for instance.  The tissues in the leaves can be very much alive, undergoing all manor of metabolism from photosynthesis and respiration through to synthesis of fatty acids.  However in the same tree the cells that make up the xylem (water carrying tissue) are completely dead – these cells have long died leaving only their cell walls to remain.

If a doctor or court were to sign a death certificate declaring you legally dead, and subsequently you came back to life, then you would have an argument that you had served your sentence completely.\n\nWhether such an argument would actually hold up in a court is arguable, because your revival would be in the same body with the same mind, fingerprints, memories, predispositions, etc. \n\nBut, it's an interesting question. \n\nHowever, if you only were medically dead for a very short time, and no death certificate was yet signed, then you would not have legally died, therefore you would not have served your entire sentence.

The real question is how do you know if you are dead.

When you die, your brain ceases to function. All of the tiny electric currents that jumped from one brain synapse to another while you were alive slow to a stop. Your body no longer functions and your brain activity soon stops completely. \n\nAt that point, the person that we knew as You is gone. \n\nBecause your body cannot be revived, your personality can never be recreated or resurrected along with the memories and other details about your life. \n\nYou have no thoughts, no pain, and no awareness of your existence. \n\nYour family and friends see the empty shell of your body, but You are not really there. You are gone forever, like millions of others who died before you. \n\nYour dreams, your loves and your hopes - gone. All that is left of you is a box of possessions you owned while you were alive and the memories that your living friends and family have of you. Your body is all that is physically left of you. It may have been buried, cremated, or donated for scientific study. If you were rich and philanthropic, a building or a charitable foundation may still bear your name. Otherwise, you may have a gravestone at a cemetery. Or nothing at all. \n\nYou do not miss your loved ones. They think of you and imagine that you are still with them, but you do not stand invisible, watching them from a distance. \n\nYou simply cease to be.

Keep in mind that all animals and humans die the same way.  The final result is brain asphyxiation or suffocation of the brain.  As long as a continued supply of blood is being transported to the brain you will remain "alive".   So, no matter how much trauma has effected your body, if your brain is still receiving a fresh blood supply you are still "alive".
