What do you think of this hypothesis? (You don't have to know much about neuroscience to understand this.)

I believe the main overall function of the brain is to imagine. To manifest to itself its own built in sense without the need for external stimuli. Considering this, I believe the eyes, ears, nose, tongue and skin receptors — although very useful — only serve as things that force the brain to use its imagining function and make the imagination correspond to external stimuli, thus becoming sense/perception. To sum it up, I believe the senses are imagination forced to behave with the outside world. What do you think?

I truly hope my brain will do more than just imagine. Since my brain controls all the other functions of my body and my ability to process thoughts, I would ask more from my brain then just imagery.

You're right, I forgot to consider the brainstem and the limbic system. I guess what I'm referring to is the cortex.

Well, I think the main purpose of the brain is to be the boss of the body and keep it alive. For lesser animals, that is exclusively the purpose of the brain. Human beings are more developed and complex and have the imagination...

So it means that it's upto the brain to choose how to react to external stimuli..................Though I agree that brain is all powerful in human body but if responses are brain's imagination then people with different imaginations should give different responses to same stimuli but most often we give the same kind of responses...........all babies cry when they are hungry...............we take our hand away from a hot cup of coffee and so forth.

Please note: "the senses are imagination forced to behave with the outside world". WITH implies specific behavior of the imagination which would be the same throughout all humans.
.
If you think about it I'm not negating the definition of the senses as we know them; I'm only saying they command the imagination; thus being sense.
Report as
Then all people have some basic senses and instincts which would command same imagination then howcome some people can imagine agreat deal and other's can't at all

To all, keep eyes out for science channels rerun of "Grand Design" with Stephen Hawkings, it really gets into the subject you are talking about.

The mind conceptualizes/integrates/refines data from all outside sources. The input mechanisms for the mind are the five senses. As one or more senses"input streams" are compromised, the mind compensates much like a computer reacts to a virus. The mind recalculates/realigns at best until it finally "blue screens".

Are you saying we don't actually sense, but only interpret the senses?
Report as
How does one fully interpret, which one has not fully experienced? Referencing FULLY. The mind has amazing abilities which allows one to respond to events not experienced or perceived correctly.
Report as
Sorry, what's your point?
Report as
Whether the input is real or imagine, one senses, reacts.

Oh very interesting, thanks!

It's an interesting theory. There is definitely a portion of the brain whose function it is to imagine. And this portion is an integral part of what it is we think of as humanity, that which separates us from the animals. But I think it's the other way around. Imagination gives us creative ways of interacting with our external environment, the one we use our senses to perceive. Rather than the senses projecting inward to fuel our imagination, I think our imagination projects outward, influencing our senses, or at least the way we interpret the data our senses relay to us. The main purpose of our brain is to formulate responses to external stimuli. Imagination helps us to see more creative options to dealing with complex situations.

Wow, fantastic explanation. You should be a writer.

Yes, that's pretty close to what's generally assumed by science. It's quiet obvious that the brain doesn't just process facts to come to objective results. We (the brain) operates a lot with preset patterns - some are already there by birth, other are shaped by experience later - and that we rather make the perceptions fit into our expectations of how thing are supposed to be. A good example are optical illusions, or effects we hear when listening to white noise, and many other misinterpretations of our senses. It's assumed that we do this to save energy and to give us quicker useable results, which we can use to act on. I guess it was a real ingenious solution that worked fine for a long time - else we wouldn't be here anymore, I guess. However, our modern life has created some problem situations where the old patterns don't work anymore and cause problems. But hey, we adapted to a lot of things in the past, so we might master that as well over the time.

The theory you just presented describes how the mind of a schizophrenic works. So I REALLY hope that's doesn't hold true for my brain..... The normal human brain takes out side stimuli and process it into the reality of what is going on around us and within our bodies, for the most part, imagination does play a lesser role. Itchy skin = bugs to the imagination, Itchy skin = rash to the normal brain.

What I mean is, while most people think imagination is reprocessing of the senses I believe the senses are conductors of the imagination. Do you understand what I mean?
Report as
It's the same thing. Either way the senses drive the imagination.
Report as
Pardon me, it's not the same thing. If the senses drive the imagination, that means the imagination is the base of the brain's fundamental function. However most people believe the imagination is a replication of sense, depicting the senses to be the fundamental.
Report as
So your theory is the all we sense is our driven by our imagination and not reality? If that were the case we wouldn't last very long as we rely on our senses for survival. The imagination and reality are very often worlds apart.
Report as
Lol. No, that's not the hypothesis. I guess I'll have to find a better way to explain it and come back later.

Maybe I'm just a little dense today....... let me know what you come up with. I love speaking with you. Your one smart cookie!!!!

Not to just jump in randomly, but also remember people like Helen Keller who was missing a good bit of her senses, but still could imagine quite well. She wrote some extremely interesting and imaginative books.
Report as
MissRia, you have an active mind but that still doesn't match my hypothesis. I'll have to try and find a good way to explain it.
Report as
I wasn't trying to match your hypothesis, I was adding that to the conversation.

"It's the same thing. Either way the senses drive the imagination."

and

"Pardon me, it's not the same thing. If the senses drive the imagination, that means the imagination is the base of the brain's fundamental function. However most people believe the imagination is a replication of sense, depicting the senses to be the fundamental."

It's really interesting to think about what your hypothesis means for someone who has no senses at all or is at least missing quite a few. Can anyone even have no senses? I don't think I've ever heard of that happening.
