All that science is very impressive but the fact remains that researchers have *no idea whatsoever* how consciousness comes about.
I repeat - no one has the slightest idea how consciousness comes about. There are many impressive guesses, and they are all just that - guesses. IIT seems promising, but the configurations needed to "turn on the lights" is unknown. By that, I mean completely unknown.
If you gave any researcher the brief to create a conscious mind, the honest ones would have no idea where to start and the rest would construct a machine that imitates the responses of animals, that pretends to be conscious.
The example was obviously a case of brain plasticity. It's not as though the brain stem is normally responsible for speech. New structures clearly emerges, enabling the baby to (at least) parrot the word "Mummy". I am also open to the idea that other structures can perform equivalent functions of the brain in simple organisms. Not so long ago it was believed that birds lacked the cognition of mammals due to a lack of a cerebral cortex. It never occurred to anyone form many years that the pallium would perform the same function.
Two papers published today in Science find birds actually have a brain that is much more similar to our complex primate organ than previously thought. For years it was assumed that the avian brain was limited in function because it lacked a neocortex. In mammals, the neocortex is the hulking, evolutionarily modern outer layer of the brain that allows for complex cognition and creativity and that makes up most of what, in vertebrates as a whole, is called the pallium. The new findings show that birds’ do, in fact, have a brain structure that is comparable to the neocortex despite taking a different shape. It turns out that at a cellular level, the brain region is laid out much like the mammal cortex, explaining why many birds exhibit advanced behaviors and abilities that have long befuddled scientists. The new work even suggests that certain birds demonstrate some degree of consciousness.

Well your statement "researchers have *no idea whatsoever* how consciousness comes about." is correct to a point.
First of all this problem exists in all emergent properties in nature, not just conscious states of a brain.
Its the disconnection of the "qualities" displayed by the causal mechanism and the emerged phenomenon that doesn't allow us to be completely knowledgeable.
i.e Gravity, we still haven't pin point its ontology even if we have identify the necessary and sufficient mechanism.(particle, emergent quality ?etc).
I think this is as far as we can go in describing the mechanisms responsible for any emergent property.
We just observe the causal mechanism and establish strong correlations with the produced phenomenon.
In reality we can not prove anything, we just identify the Necessary and Sufficient conditions for a phenomenon to emerge.
We may even stare the actual cause in the face but because of the emergent quality of the phenomenon we will always believe we miss something!
Sure in the complex case of brain states we have some more descriptive work to do in order to identify all the mechanisms of the system.
But we do know way to many thing to even have a discussion under the Opening Question of this thread.
i.e.We can arouse a specific brain area of patients (central lateral thalamus) who are under general anesthesia and bring them in to a conscious states where they are aware of all environmental stimuli without any signs of the side effects of the drug!!!. We can diagnose loss of consciousness (or a specific quality of it) based on the injury of a specific brain module and we can tell when a guy is conscious and what is the conscious content of a specific thought through fMRI scanning. Sure we have some miss fires now and then, but we can never claim absolute knowledge or absolute uniformity in complex biological systems.
So we don't really need to "build" an machine to imitate consciousness in order to say that we understand the neurology of our conscious states.
Like in Gravity, or mitosis, or photosynthesis or digestion, we just have to describe the causal mechanisms and produce testable predictions and technical applications.
I don't know why we need a paper to tell us something so obvious...that birds have some degree of consciousness!
All that sensory input of stimuli (eyes,hearing, smell,touch) need to be consciously processed, categorized and retrieved under different conditions.
We know birds interact and learn their environment and their behavior can be affected by previous experiences/They even display superstitious behavior because of their learning abilities and they need to deal with a chaotic environment!
If we "make the mistake" and decide to talk about crows, then we are dealing with puzzle solving machines capable to grasp "meaning", see purpose and intention(mind theory) and develop different "culture" within different populations.
I think people confuse conscious states with conscious content of a state and that is also a problem in the different scientific definitions of consciousness!
It is a fact that a bird can prioritize an important stimuli and process it nature and quality consciously based on inputs from other areas of its brain responsible for i.e. memory, pattern recognition, urges and emotions,social behavior.
In humans thought our conscious content is enriched by our ability to use symbolic language and reason our emotions in to feelings allowing us to introduce way deeper meaning and high number of concepts.
Consciousness is the third most important mind property (According to Cognitive Science and Neuropsychoanalysis) after Awakeness and Unconscious Self awareness. This is an other huge problem. Most people who participate in discussions like this one aren't able to distinguish consciousness from the rest of the properties of the mind or the mind it self. So in order to even talk about what consciousness is or how it emerges, we need to define the different aspects and qualities of the phenomenon and understand what other people mean by that word.
