how is will power connected to neurons of the brain?

Question

It seems we can change our behaviour with our willpower.
From where does our will power emanate in our brain?
Does it also have specific neurons?
Neuron's dendritic length, can it be altered?

Answer 1

When I hear "willpower," I think of executive functioning. Executive functioning are your abilities to make decisions and plan. You need executive functioning to do any goal-directed activity and to change behaviors. Researchers believe that executive functioning is mediated by the frontal lobes. They have found that people who have had brain injuries to the frontal lobes have difficulty with impulse control and planning.
Your neurons are not fixed in size. Over the first few years of life, the brain grows rapidly. By the time an infant is two or three years old, the number of synapses (that space between neurons) is approximately 15,000 synapses per neuron. Adults have about half this. As we age, old connections are deleted through a process called synaptic pruning. Synaptic pruning eliminates weaker synaptic contacts while stronger connections are kept and strengthened.
Dendrites can grow, using structures called Golgi outposts.

Answer 2

You seem to be approaching the problem empirically.

That is fine, but you must realize that there is an interpretive side to the brain function, and that is the most difficult to quantify and understand.

I don't think that it matters where will power originates in the brain or what neurons are activated by that process.

Those are questions to be answered by scientists in an empirical fashion.

The more interesting question to me is how consciousness works.

We can answer that question somewhat by using interpretation. We can ask others, or even ourselves, what thought processes trigger certain mental and physical reactions.

However, your basic premise that your actions can be controlled by your consciousness is true.

Just how that process unfolds is still a mystery to be solved later.
