What happens with the electrical energy within the body when we die?

In summary: This process is entirely different from the chemical processes that are used to create the energy in the first place. In summary, when we die, the chemical reactions that create electrical energy in our bodies stop and the stored electrical energy dissipates. This is different from the energy created by food and oxygen, which is used up in these reactions.

What happens with the electrical energy within the body when we die?

I've been thinking about this for weeks, and even though I'm not that great at it,
I find anything scientific interesting. I truly have compulsive documentary watching disorder :p
I watch new ones every day, and if I don't have a new one, I'll just rewatch ones i have.

But back to my question..
Even though I'm probably way off in terms of the science, here's what I was thinking. Since energy cannot be created nor destroyed it has to go somewhere, right?
Well where does it go? Of course the actual body will most likely be incinerated and turn into heat energy, but what about the electrical energy in our brains? Electricity can't be incinerated? Makes me think about Duncan MacDougall for some reason :p

What do you think happens when lightning strikes a mountain? Compared to that, the amount of electrical energy in our bodies is miniscule.

A couple of things.

1. "Electrical Energy" is created in our body by chemical reactions that occur when we are alive. When the body dies these reactions stop and no more energy is created. The energy is used right after it is created to perform different actions.

2. Our bodies take in food and oxygen and through chemical reactions is transformed into other forms that are then either used or stored as fat, sugar, etc. So there is no electrical energy just floating around or anything like that. The sugar and fat is taken in and used to power the reactions that create the electrical energy.

3. Electricity is a vague term that doesn't really say anything specific. When speaking of electrical effects, we talk about electric current, potential, resistance, and other things. It is commonly viewed that all of these concepts fall under the "category" of electricity. So when you ask about electricity being incinerated, it's not really a valid question. If i were to burn a corpse, the atoms and molecules that make it up take their chemical potential energy and use it to re-organize themselves through chemical reactons into different molecules. This uses up the energy. Since your body doesn't store electrical energy, but instead stores chemical energy, this energy is used up after you die when you decompose and such.

Interesting. Thanks for the reply :)

The electricity in the body is stored as membrane potentials. That is, ions of a certain sign are pumped through a cell membrane so that a difference in potential exists, somewhat like a battery. After death the pumping stops and the charge dissipates.

1. What happens to the electrical activity in the brain when we die?

When a person dies, the brain stops receiving oxygen and nutrients, causing the cells to die. As a result, there is a decrease in electrical activity in the brain. This can be seen in an electroencephalogram (EEG) which measures brain activity.

2. Does all electrical activity in the body cease when we die?

No, not all electrical activity in the body ceases when we die. While brain activity may stop, there are still electrical processes happening in other parts of the body, such as the heart and muscles. This is because these organs have their own electrical systems that can continue to function for a short period of time after death.

3. Is there a surge of electrical energy in the body at the moment of death?

There is no scientific evidence to suggest that there is a surge of electrical energy in the body at the moment of death. Some people may experience a surge of energy in the form of muscle contractions or spasms, but this is a natural response and not a surge of electrical energy.

4. Can electrical energy be transferred or preserved after death?

No, electrical energy cannot be transferred or preserved after death. Once a person dies, the body's systems begin to shut down and the electrical energy dissipates. It cannot be transferred to another person or preserved for future use.

5. Is there a link between near-death experiences and electrical activity in the brain?

While there is ongoing research on near-death experiences, there is no conclusive evidence to suggest that they are linked to electrical activity in the brain. Some theories propose that these experiences may be a result of changes in brain chemistry or other physiological factors, rather than purely electrical activity.
