Is there any physical evidence for inner monologue?

Question

Everybody has it, that voice inside your mind only you can hear.
When you think of something to say to someone, when you write a question for Yahoo Answers, even when you go grocery shopping.
The sound of your own voice, interpreted by your brain.

Now, is there any evidence for the presence of your voice? Can an MRI scan or any other scientific piece of equipment, detect this as say, neurons flaring or such?

Or is this something that can't be detected by the technology we currently have?

(Please note, this is in the Psychology section, not Religion. Please refrain from any theological answers please.)

Wise Man, believe me, I think too heavily on the philosophical side of things, I like to mix it up now and then to see how other people think of things. :P

I get what you're saying, much appreciated.

Answer 1

Some people think more in spatial terms. Some people will visualize their thoughts rather than verbalize them.

The way thought processes are performed within our brains is different for every person.

If you really want to get philosophical, drop this monologue and talking to ourselves business and start asking yourself where a thought comes from. We can explain the biological aspects of thought, but we cannot explain where creativity and abstract thoughts come from. Part subconscious, part conscious, but it will forever remain a mystery... the spontanaety of a being.

Answer 2

Conscience is an ability or faculty or sense that leads to feelings of remorse when we do things that go against our moral values, or which informs our moral judgment before performing such an action. Such feelings are not intellectually reached, though they may cause us to 'examine our conscience' and review those moral precepts, or perhaps resolve to avoid repeating the behaviour.

Commonly used metaphors refer to the "voice of conscience" or "voice within."

One has to practice Yoga to listen to the inner monologue.
Yoga is not connected with religion.

Answer 3

Usually that monologue is just a version of thought. MRI's can detect thought. It can't say what kind of activity is happening but it can say there is activity.
