Is there electricity in my brain? (Age 8)

Wow that is a really good science question! Yes, there is electricity in the brain but it is in a different form from the type of electricity that powers the television. When we describe the electricity in a television, we can explain that it is created by electrons being pushed through a tunnel called a circuit. However, the electricity in our brain is a little more complicated. Inside brain cells are molecules; these molecules are made up of tiny neurons that are charged with energy. Special chemical de-coders called neurotransmitters help the body receive the electrical charges from the tiny neurons. These neurotransmitters are responsible for making a pathway for the energy to travel through the body's cells. Once the electrical charges have reached a nerve, the body's nervous system can interpret what to do, like move certain muscles or feel pain if we hurt ourselves. The important thing to understand is that the electricity in our brain is a mix of neurons that have energy and chemicals (neurotransmitters) that move the neuron's electrical signals to the rest of the body. The electricity needed to power the television does not need to have chemicals to move the electrical signals.

Now that you know how the brain uses energy, keep using your own brain to be a good scientist!

Wow, never thought of neurotransmitters as electricity in the brain before, but that's a really cool concept. There are also foods that are high in neurotransmitter stimulation aren't there? Like if you eat chicken with walnuts and cranberries, that's brain food isn't it?

There are a number of brain foods, but actually consuming them each day is hard. I take an organic, natural supplement ( every day so that I know I'm not missing out on anything essential.

Who is Professor Science and what are his or her qualifications?

Uh, these molecules are made of neurons? Excuse me, Professor Science, but that doesn't sound quite right. Are there really any molecules made of neurons?

what happens to the electric energy of the brain during the death process?

It is an amazing fact to learn, about how the brain works with electricity. It is not so surprising as creatures such as the eel also have some electricity in their bodies. Even though this electricity may not be as the electricity obtained through sources like the wind, coal, or water, it is able to make the brain function with tremendous speed. The speed at which the natural body responds to reflex actions may be able to explain how this electricity in the brain works in the body. The brain is an amazing wonder of nature with its ability to perform several tasks at the same time and sometimes have results faster than some man-made machines which work with electricity.

Dear Robert Corbin, while I praise your intention, the execution was deeply flawed. Please correct the article. It is very wrong. Molecules are not made of neurons. Neurotransmitters do not help the body receive the energy from he neurons. What really happens is that neurons, once activated, can take calcium, sodium and potassium (which are electrically charged), and when these "ions" reach critical values, a current is produced. The current makes the neuron release neurotransmitters, which in turn activate other neurons. These signals in the end result in, for example, muscles fibers spending energy to move... but not because the neurons generated that energy.
