I guess what irks me is that there actually is a fair amount of information about the neuroscience behind things like perception, memory, language, learning or emotion etc. - a lot of it a click away on Wikipedia. But there's this odd assumption that "Well, I have a brain, so I must know how it works, and if I can't explain how the brain performs some task, it must be mysterious." There's no other area of science I can think of where so many people do this. I'm not criticizing anyone for asking questions, or not knowing something , just the tendency to make sh1t up willy nilly.

Why do discussions about consciousness always go off the rails?
The emotional tag is useful to an animal since, if a similar memory is triggered; sensory induced recall, the memory will induce the emotional tag. For example, if an animal was to find a food item, it once ate, which tasted good, by seeing it again, the food item will induce that same good feeling. The result is the animal will eat, without having to think, by reacting to the feeling. There is more emotional tagging in warm blooded animals, allowing a more complex social interaction, based on sensory cues.
I am also surprised by a phrase like "which tasted good". This language seems to infer conscious experience when it is possible that in some animals the signal from the sensing cells to the matches memory of those signals and generates a chemical response to consume the food automatically or may be it is completely automatic without memory at all.

I find it frustrating that these discussions always jump from neurons to the functions of areas of the brain. I hasten to say that I always find the subject interesting and this is not just abuse.I am also surprised by a phrase like "which tasted good". This language seems to infer conscious experience when it is possible that in some animals the signal from the sensing cells to the matches memory of those signals and generates a chemical response to consume the food automatically or may be it is completely automatic without memory at all. Your example is particularly relevant because this simple response evolves to a much more complex response as the organism evolves more specialised limbs and organs. The chemical response is moved to the gut. The sensing moves to the nose (for example) and a simple random movement the whole animal is now a complex movement of the snout and sniffing which are still automatic. The response to the food could still be automatic or use memory. If the organism uses eyes as well as smell it now has to use memory. It is combining a massive amount of processing of the signals from the eyes to recognise the food but it has no knowledge of the value of the thing which is seen as food until it is tasted. Then the visual memory has to be combined with the memory of a signal from the taste buds. It might also have be using smell first and maybe memory of location. It is probably going to record location if the feeding is successful. This is so simplified that I hesitate to offer it as a description.I believe that every step from the simple to the complex is matched in the brain and with enough knowledge of these steps we could discover much about the way consciousness works. The key is the combination of sensors, signals memory and the memory of the sensation of the response. What I have described is really only awareness and has no conscious thought as we would discuss it. I do think that self awareness is necessitated by the linking of sight and manipulation of paws or similar limbs. If I see a hand move a book there is no intrinsic way of identifying the mover without combining the visual signal with touch and there is only correlation of the two sensations to establish who did it.I have run out of time to so this argument is not complete but it is a start.
I began the discussion of consciousness, at neurons, because neurons work differently from computer memory. This was important because most analogies for consciousness think in terms of computers.
There are two centers of human consciousness, one center each, for the both conscious and the unconscious minds. The studied cited seems to be connected to the secondary center, which to most people, is assumed to be the only center. The primary center is far less conscious and is called the inner self. The primary center is shared by animals. Humans are unique in that we also have the secondary center, called the ego center, which is the center of the conscious mind. If you sleep and have no awareness of dreams, the secondary center is switched off. The primary center can still active, working the brain in a more integrated fashion; free energy movement.

This was important because most analogies for consciousness think in terms of computers. I agree completely that computers are a poor analogy for the brain. As you say constant change is vital to the understanding of the mind. The brain uses feedback all the time. Even talking about an event changes the memory of that event. The activity of the brain is always effected by the physical context e.g. tiredness or hunger. It is effected by location. You think and behave differently if you are at home, at work, or playing sport etc. The chemistry of the brain is different in these circumstances and different memories are available. Consciousness can include most areas of the brain which makes me think there are not specific areas of consciousness.

Because nobody ever defines consciousness, or if they do, nobody else accepts the definition.
Erika asked the Naked Scientists: Where in our brains does consciousness lie?What do you think?
Consciousness is an illusion. It's a trick played on you by your genes.
Quote from: snorkfort on 08/08/2017 22:58:43Consciousness is an illusion. It's a trick played on you by your genes. I disagree, consciousness is independent from our genetic code (and brain), as it has been demonstrated experimentally that animal consciousness can survives a head transplant.See: http://www.express.co.uk/news/science/798032/Neurosurgeon-bring-cryogenic-dead-BACK-TO-LIFE-brain-transplant
You do realize that a transplanted head still has a brain in it, right?
Quote from: Kryptid on 12/08/2017 00:33:54You do realize that a transplanted head still has a brain in it, right?That is irrelevant to the OP. The purpose of a head/brain transplant is to demonstrate the "atomic singularity" of human consciousness as a fundamental aspect of life. Without consciousness there is no life. The brain is merely a evolutionary quantum computer to transcode the atomic singularity of consciousness into neuroholographic memory.
Various forms of life do not have consciousness. E.g. plants, lichen, bacteria, fungi, etc.
Quote from: snorkfort on 15/08/2017 00:00:33Various forms of life do not have consciousness. E.g. plants, lichen, bacteria, fungi, etc. Yeah right. What evidence do you have to prove this claim? The question whether plants are conscious is controversial.See: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4594572/
