/////////////////////////OVERMx AND UNDERMx


//////////////////////////BRWSR=Consciousness, in short, is a matter of the qualitative experiences that we have. To understand qualitativeness, think of the difference between drinking beer, listening to music, and thinking about your income tax. Each experience has a distinct quality.

Because of this qualitative character all conscious states are essentially subjective in the sense that they exist only as experienced by a subject—human or animal.


/////////////////////////////NCC= NEURAL CORRELATE OF CONSC

////////////////////////////............ How does the brain construct a mind? and (2) How does the brain make the mind conscious? The brain creates a mind by creating images, which are unconscious momentary patterns on sheets of neurons called maps. The images may be either of parts of the body or of things outside the body, but in general, perception is the result of mapping. Damasio says, “The distinctive feature of brains such as the one we own is their uncanny ability to create maps.”


///////////////////////////CONSC=“a state of mind in which there is knowledge of one’s own existence and of the existence of surroundings”


///////////////////////////////............The Self. The self is a much harder notion to define, and I do not find his definitions entirely clear. He says the self is decomposable into three components, the protoself, the core self, and the autobiographical self. Each of these can come in two forms, the “self-as-object” and the “self-as-knower.” But the self-as-object can also operate as knower.


///////////////////////////...........he protoself is constituted by special kinds of mental images of the body produced in body-mapping structures, below the level of the cerebral cortex. The protoself is “an integrated collection of separate neural patterns that map, moment by moment, the most stable aspects of the organism’s physical structure” (italics in original). The first product of the protoself is “primordial feelings.” Whenever you are awake there has to be some form of feeling. The second form of the self, the “core self,” is about action. “The core self unfolds in a sequence of images that describe an object engaging the protoself and modifying that protoself, including its primordial feelings.” These images are now conscious because they have encountered the self. Finally there is the autobiographical self, constituted in large part by memories of facts and events about the self and about its social setting. The protoself and the core self constitute a “material me.” The autobiographical self constitutes a “social me.” Our sense of person and identity is in the autobiographical self.


////////////////////////////..........Damasio tells us that there are two kinds of qualia: Qualia I and Qualia II. Qualia I is about pain and pleasure, but the problem of Qualia II is why there should be any feelings at all. He thinks Qualia I is not a mystery but that the Qualia II problem is more difficult


/////////////////////////..............think we intuitively identify ourselves with the conscious events that we experience as occurring in working memory, and we tend to believe that these events include such things as judgments and decisions. But in my view, they don’t, and these sensory-involving events are merely the effects of the activity of the self, rather than constituting the self. This occasions a radical change in perspective on ourselves. For the self and its attitudes is something completely submerged from view, directing and orchestrating the show of sensory events that parade before us in working memory.



/////////////////////////...........humanity "transcends apehood to the same degree by which life transcends mundane chemistry and physics"



////////////////////////////////.............Sentition is "a privatised expressive activity", whereby the sensation of the redness of a tomato, for example, means nothing other than for you to observe your own active "redding"


//////////////////////////////..............As for the ipsundrum, this is the seed of the self, analogous to illusory or impossible objects such as the Penrose triangle, which somehow generates the illusion of a world out there corresponding to a me "in here", though it still has to be "'seen' by an internal observer". It is, we are told, a "mathematical object", "a complex pattern of dynamic activity in neural circuits".



/////////////////////////////............are doomed to act as if we were conscious, knowing that we are merely atoms, just as we are doomed to keep going even though we know it's a dead end. We will keep talking of responsibility, freedom, and punishment and act as if it all was not some shadow show. We will write comments in the full knowledge that we are no more masters of our fates than rocks, and stones, and trees. But sometimes it's fun for some.


//////////////////////////////,,,,,,,,,,,,, Don't let your inner deterministic biological overlord convince you that you've pulled back the curtain and seen the whole show. It necessarily distracts you from the gap of freedom that is required, but is necessarily not in view, to present a recognizable picture, a picture that remains open to improvisation.


/////////////////////////////..............It was a Japanese surgeon who performed the first known surgery under anaesthetic, in 1804, using a mixture of potent herbs. In the west, the first operation under general anaesthetic took place at Massachusetts General Hospital in 1846.


//////////////////////////..............dreams do not occur in our sleep as is the common belief but are a part of the brain firing up into wakefullness or - consciousness. So dreaming consciousness is a part of waking consciousness.

 Paradoxically we can only be aware of our dreams when we are awake.


/////////////////////////AWAKENING-ZOLPIDEM=zolpidem awakening came from South Africa, in 1999. A patient named Louis Viljoen, who, three years before, was declared vegetative after he was hit by a truck, had taken to clawing at his mattress during the night. Thinking he was suffering from insomnia, his family doctor suggested zolpidem to help him sleep. But 20 minutes after his mother ground the tablet up and fed it to him through a straw, Viljoen began to stir. His eyes, which normally wandered the room, vacant and unfocused, flickered with the light of consciousness. And then he began to talk (his first words were “Hello, Mummy”), and move (he could control his limbs and facial muscles). A few hours later he became unresponsive. But the next day, and for many days after that, zolpidem revived him, a few hours at a time.


////////////////////////////AMBER= GO ON 3 MORE CARS


///////////////////////////............cousin came out of a coma after almost ninety days in a dream (thats his own description of his consciousness), To others he was in a vegetative state. His turnaround occurred after he got the flu. Somehow the illness prompted something to heal and now he's almost the same as he used to be, although he does have some problems with his eye. Four years later he's working and he's supporting his family. He surprised everyone.
