Nature of perception

[imported_Berserk_Exodus]

Your mind is made up of billions of nerves correct? Doesn't that include the nerve tissue all around the body? So, your concioussness carries light frequencies through the eye nerve tissue to the brain. The nerve tissue all through the body is the same principle except that it interprets changes in movement, temperature, etc. That's why in the center of your eye you see a wierd warped structure in the center of your vision. That's obviously your lens. The light travels directly to your brain as you receive it. Basically dreams are a record of your day in your head, along with the fantasies and the thoughts in your head. The reason that the light usually isn't vivid in the brain is that the brain can simulate light and create scenarios. But the eyes are closed so it kind of decreases the amount of realness to the dream. What it is like is fiber opitics. You can receive light and the light travels through the tissue to the concioussness inhabiting the brain. That's what it would have to be, just like cameras on a machine. Just remote control...

There have been many studies performed relating vision to imagination. Time and time again it has been found that seeing an apple activates the same parts of the brain as envisioning a apple in your mind with your eyes closed. Light has nothing to do with it.

There is a difference, at least for me, between the thought vision and real vision. That is because it is perception of actual light through nerves which connect to the eyes.

Just because it activates the same part of the brain doesn't mean that other parts of the brain and other factors do not come into play. other areas of the brain may become stimulated as a result of another part of the brain. There are many factors to consider. And these studies. Are they Scientific proof?

[bradybaker]

Depending on your definition of the word "proof", yes. At the very least they are examples of very, very strong evidence. These tests used highly detailed and precise brain imaging techniques. The specific part of the brain may be activated in different ways, but the result is the same.

I wouldn't say that. I've had dreams as vivid as anything I've seen in real life. Some arguably more vivid.

The lens focuses light on specialized tissues that translate it into chemical and electrical signals. Those signals are translated several more times before they reach the brain, which processes them, assembles a visual field, breaks that field down into smaller parts based on past experience, prioritizes those parts (again, based on past experience), and only at this point do we "see" anything. What we do see is very much conditioned by what we expect to see and what we have seen in the past. Perception seems instantaneous and direct because we're only aware of the finished product, in the same way that a movie assembled from hundreds of takes seems like a seamless whole in the theater. This process is very adaptive for processing the vast sensory data available to us in every moment, but our perceptions are not "reality." What we see in waking life reflects our inner landscape just as much as what we dream reflects our waking lives.

Seeing an apple through your mind is the exact same as an apple with your eyes. The only difference is that you are well aware, if only on a sub-conscience level, that when you shut your eyes thatthe apple is not real, and so you think about it differently.
