It may be of interest that the Human Brain Project has been awarded a European Flagship Grant of 1 billion euros(!). The other recipient of 1 billion euros under the EFG was graphene research.
 
When one comes across someone in these threads who has less interest in a dialog than he has in repeating his own empty pompous proclamations, it's time to withdraw. Bye for now.
 
Dear Forum,

I can see that this conversation concerning the nature of light and colors has not generated a discussion group yet. I hope that given time, it will mature into a more productive conversation and morph back to discussing consciousness. Tweets are poor conversation...

Mr. Scott, I use dictionary definitions of words; I learned to read and write out of dictionaries. I take it that you mean using words like "illusion" or "hallucination" to describe visual acuity, is out of the costmary context in which you and many others have used them in relationship to talking about psychological disorders. My use of those words, in their context, is proper. I can see that you are not comfortable having those words associated with normal neural activity. The English language does not offer other 'simple to the point' words to replace their meaning/definition. We write with the words that we have to work with. If you are familiar with other common words that could be used in their place, I would like to know what they are; I would consider using them if they offer a more appropriate definition.

Synesthesia is a fascinating subject. However, adding it into this discussion would further muddle my discussion on light and colors, and ultimately our conversation of consciousness and memory. If you would like to start a thread on that topic, I would certainly engage in conversation regarding it.

Zeuzzz, I watch the videos you listed, interesting contribution to the discussion. I have not seen the first one before. The ability to calculate perspective has to have preexisting-neural-wiring to be able to recognize perspective. Perspective can be learned in many ways, normally through vision, but it can also be learn through tactile experience (touch,) or sound. You may have noticed that in the video they did not talk about his younger years as an artist, years when he was experimenting and learning to paint and draw in tactile perspective. I also noticed that his sky impressions had color diffusion/gradients, which required extensive descriptions and coordination from other people before he was able to finger-paint them on his own. He did not get it all right, did you notice the huge bush on top of the windmill roof, or the two sail windmills. If you look at his house and river picture more closely, you will notice that his perspectives are considerably off. He uses tactile perspective (touching) to form a mental image, and then transfers it to his hands. Esref Armagan demonstrates learned perspective skills, not necessarily extraordinary skills. I do not think spending time and rescores on studying his particular skills is warranted. The relevance of the video is that he was able to learn perspective because his brain was genetically pre-wired to process perspective.

I saw the second video about ten years ago. I have studied the phenomena of near death experiences for many years; very interesting neurological response. Though I recognized many parts of this video, I do not remember the blind women's experience and testimony; maybe I went for a cup of coffee when she gave her story. However, most of her experience is typical with the exception of first sight. She claims to visually recognizing things such as her ring, hair, trees, birds, and sky light that she has never seen before. In the few cases where blind people have been given sight for the first time, they have no idea what they are seeing; it takes them a long time to learn to recognize objects. They never develop three-dimensional vision or perspective; their vision is a flat mosaic of light and colors in two dimensions without depth perception. Her story cannot be true because of this. The real intent of the entire video is to suggest a next-life existence, using near death experience as their evidence. There are no tangible facts, just testimony. Testimony has been used for thousands of years as a social engineering tool to generate conceptual beliefs. No matter how convincing her story sounds, without tangible facts, it is only a mediavision story. In spite of that, what she does demonstrate is her brain's ability to generate visual sensations even though she has never seen.

The videos were useful. Thank you for the contribution.

dlorde, oh darn, is mediavision a neologism :) Yes, I do insist on calling light and colors a neural illusion. If light and colors do not exist outside the brain, a neural illusion is the correct depiction. You use elusion to neural illusion. Obviously, you do not agree with my assessment of the neural nature of light and colors. You may see it differently down the road.

I have no intention of being patronizing on any level; you misunderstand my writing style. I think Zeuzzz hit it on the head when he/she stated I write succinctly, you are taking offense when none is intended.

You suggested that most of you have degrees; I always get wary when someone holds up a degree as testament to their knowledge. A degree cannot speak for you... your words are what speak for you. Degrees talk about your background education, not necessarily your aptitude or competency. Let the knowledge of your words do that... whether you have a degree or not.

I watched the Human Brain Project video you offered. It was about a futuristic research project wanting to use computers to attempt to mimic or simulate a biological neural network for electronic applications. How is that relevant to this discussion of light and colors? Could you connect the dots for me?

Did you notice that the video stated that the technology already exists? That simply is not true. The software alone would be one of the greatest projects humanity has ever attempted. Many modern software programs have millions of lines of code and require hundreds and sometimes thousands of people to write. A software program that mimics a neural network would take billions of lines of code, and hundreds-of-thousands of people to write over many years. That video was a seven-minute commercial for a website; if you click on Research Areas, then Future Neuroscience, they spell out the challenges. If you read it carefully, you will realize that they have no actual idea how to compose it, just underdeveloped theories. They make bold claims that are well beyond their capabilities in the near future. At best, they may be able to lay groundwork for future endeavors.

They did talk about memory in many of their website sections, do you think they will have to base the entire system on memory before it works? After all, what is an impulse without a memory definition?

Knowledge is like a mountain, you have to do the hard work to climb it before you get to the top; from up there - you see new horizons,

None of our perceptions of the world exist outside the brain. By this logic, our entire perceptual world is an illusion. I don't see where this gets you. We know our perceptual world is a mental construct, I already mentioned it; and we've spent interminable hours here arguing the ins and outs of qualia and the neuroscience of perceptual awareness.

You use elusion to neural illusion.
:confused: sorry, I can't parse that.

I'm well aware that colours and the perception of light are internal, mental constructs, if that's what you mean. It's unrelated to your unconventional use of 'illusion'.

I have no intention of being patronizing on any level; you misunderstand my writing style. I think Zeuzzz hit it on the head when he/she stated I write succinctly, you are taking offense when none is intended.
OK. I'm not offended, I just thought you'd find a more receptive audience with a different approach. If you can't see how the quote I posted appears patronizing, then so be it.

You suggested that most of you have degrees;
Not quite. I said most are familiar with the topics, many have relevant graduate or postgraduate qualifications.

I always get wary when someone holds up a degree as testament to their knowledge. A degree cannot speak for you... your words are what speak for you. Degrees talk about your background education, not necessarily your aptitude or competency. Let the knowledge of your words do that... whether you have a degree or not.
The point was simply that most of us are familiar with the subjects, many are very familiar. Your posts gave the impression you were not aware of that.

It is relevant to the thread.

Odd - I distinctly remember them saying the computing power didn't yet exist, but on the planned timeline, it should do by the time they're ready to use it.

The software alone would be one of the greatest projects humanity has ever attempted. Many modern software programs have millions of lines of code and require hundreds and sometimes thousands of people to write. A software program that mimics a neural network would take billions of lines of code, and hundreds-of-thousands of people to write over many years.
They're using neuromorphic chips for the main implementation, not software emulation (although they will be able to model subunits using a software emulation). Either way, software neural network emulations don't require the amount of code you seem to imagine, and fortunately much of the brain is based on repeating structural units (cortical columns).

I did read it; it seemed reasonable enough, given current state of the art. YMMV.

Not sure what you mean - can you be more specific, i.e. less vague?

Yes, I'm sure you do.
 
Dear Forum,

Um sure Mark Maloney, whatever. try engaging in a dialogue instead of just asserting your conclusions.

The fact that you insist your personal idiom is the only correct one makes you appear monomaniacal.

I notice you refuse to address the fact that you are not using the standard definitions of hallucination and illusion by the sciences of psychology and neurology?

Why is that? If you want to discuss consciousness, would it not be better to find common language instead of insisting on your personal idiom?
 
[...] I use dictionary definitions of words; I learned to read and write out of dictionaries.
Perhaps you could quote those dictionary definitions so that we can see what the proper definitions are?

As it has been pointed out, your use of "illusion" and "invisible" make the terms useless. What do you gain from this use?
 
Dear Forum,

It might be a good idea to take a poll to see where everyone stands at this time on the discussion of whether light and colors exist outside our imagination.

Is the universe illuminated outside our brain?

OR

Does light and colors only exist within our brain?

I like to hear your reasoning for your answers, whatever it is, if you have a little time,

Sincerely, Mark Maloney

Wow, did I just do a tweet,
 
Light is a small part of the electromagnetic radiation spectrum that we can detect with our eyes. We further carve this band up into colour categories with the distinctions rooted in our trichromatic detection system. Our theories about them are constructed narratives shaped by our testing of their predictive power against experiences in the world. Our brains build a conscious experience of light and colour from ocular input, providing an important tool in our navigating the world we live in.

Why limit the question to light and colors? Does the universe itself exist outside our brains? Do you exist outside my brain?

Are you sure these questions make sense?

Laser is light. A laser can burn you. If you are burnt by a laser, does that only happen in your brain?

Why?

You've already had a number of explanations of these phenomena; what is your point?

If you really want to, you can create a poll when you start a new thread.

If visible light is invisible, then is audible sound inaudible?

If a tree falls in a forest, and no one is there to hear it, does it make a sound?

If Mark ignores what we say, did we say anything?

Come on, Mark, play with us.
 
Dear Forum,

I can see that many of you are having difficulty staying on subject. Instead of employing thoughtful responses, many resort to tweet replies that have nothing to do with the subject; your posting numbers go up, but your acquired knowledge is stagnate, maybe even declining because tweets damage your ability to critically think. This website was designed to foster critical thinking skills, tweets are counterproductive. Thoughtful discussion on topic is always productive.

Since the majority of recent posts to this thread have been obstructionist in nature, I would like to offer a different approach to help foster critical thinking skills. If you think my posts concerning the nature of light and colors are wrong, dissect them, and through research and thoughtful deliberation compose a post explanation of why you believe they are wrong. We have nothing to lose but ignorance, and everything to gain through shared knowledge.

Each one of you has an opportunity to educate the rest of us,

Sincerely, Mark Maloney
 
Dear Mr Maloney,

I had a crack at your assignment but must have come up short of your expectations.

Humble apologies,

John

Dear Mark,

I can see that you are having difficulty staying on subject, consciousness. Instead of employing thoughtful responses, you resort to soapbox rhetoric that has nothing to do with the subject; your posting numbers go up, but your acquired knowledge is stagnant. This website was designed to foster critical thinking skills, and thoughtful discussion on topic is always welcome and productive.

Since the majority of your posts to this thread have been wildly off-topic, it would be nice to see you accept this forum as an opportunity to learn.

Sincerely, a Forum Member

Re the bolded comment, various replies explaining your error have been made; perhaps reading with comprehension is not your strong suit.

Sorry but this isn't all about you. You made a series of statements about the nature of light etc., which are to put it mildly idiosyncratic. You have refused to respond to the rather obvious and pointed out problems with your opinion. I frankly see little difference between your position and solipsism, the idea that reality is all in your head. There is seems to be little point in discussing things with you because it seems to require that we accept your unusual definition of visible and invisible for example.

As for your stuff about the nature of light well the simple fact we see indicates that something is not invisible. Unless you stack the deck by semantically redefining the term.
