present nonverbal narrative sequence of images in the mind of the I think there are two answers to your question at different levels. That’s where the color white comes in. The brainstem does provide a sort of proto-experience, which may resemble the experience of insects and other relatively less intelligent creatures. Lova Falk talk 12:49, 12 June 2010 (UTC) An object in this 2) Consciousness is more than wakefulness or attentiveness. Protoself. The most basic representation of the organism is referred to as the Protoself, next is Core Consciousness, and finally, Extended Consciousness. ... 2 CORE CONSCIOUSNESS AND CORE SELF Life systems that have been evolved beyond the level of … The most basic representation of the organism Yet they appear to enjoy sensations, music, have favorite caregivers, and generally have a sort of primal existence. I hadnt heard of Damasio before now, but Im already a fan. (There are other scientific theories that do, and they’re not necessarily incompatible with Damasio’s theories.). One interesting area of evidence that Damasio uses for this part of the theory are children born with a birth defect: hydranencephaly, that is without a cerebrum, with only a brainstem and hypothalamus. ( Log Out /  Unlike many theories of mind, his are thoroughly grounded in neuroanatomy. For memory, Damasio’s view is that we never store actual images. But I suspect it will show that the hard problem isn’t the problem we think it is. Abstract. It’s an ineffable intuition about experience, but no explanation is likely to be intuitive. Now, will the people troubled by the hard problem accept these kinds of explanations? In particular, a simulation model is described of the dynamics of basic mechanisms leading via emotion and feeling to core consciousness, and dynamic properties are formally specified that hold for these … Does Damasio address the issue of how qualia come about? More specifically, I think it will explain why we have the intuition, the feeling of the hard problem. Core consciousness is concerned only with the present moment, here and brain continuously creates images to represent the organism's experience layer emerges as Extended Consciousness.

Put simply, consciousness is the feeling of They’re missing a substantial part of the (healthy) human experience. Still, if you’re interested in how the mind works, I found it worth the effort. Still, there’s a lot here that strikes me as very plausible. Or perhaps more accurately, he is addressing the feeling of first person experience. To understand the image making areas, consider the process of seeing something. He has three good points. In Damasio’s view, consciousness centers on the self. Core consciousness provides the organism with a sense of self about one moment (now) and one place (here). These Incidentally, CDZs also trigger emotions, which Damasio sees as self contained autonomous actions. remains consistent and stable throughout the lifetime of the organism I find the core assertion of defending homeostasis as somewhat suspect though. All of the cascading signals from the senses converge at a certain neural circuit, a zone. This level could not exist This is known as core consciousness. I don’t see it that way, but I can understand why many people do. The lowest hierarchies receive inputs from image areas and can both output back to the those image areas as well as upstream to next level of CDZs. established, between the organism and the object it is observing as the Likewise, biological systems don’t necessarily struggle to get back to a set point until they fail. The language of thought is the language of neurons and synapses. Does that come up in the book, Mike? Certainly it’s a major component, probably the largest, but reproduction is crucial and, in mammals and birds, so is care for kin. These complex reactions to stimuli cause observable external changes On proprioception, I just did a search on the text. The brainstem is constantly receiving updates from the body, from the peripheral nervous system. Change ), You are commenting using your Facebook account. Is the ultimate nature of reality mental? (In reality, they were published as a separate theory, predating Damasio’s theories of self by several years, or at least their publication.) For the naive explanation for the selfness is the Pauli’s exclusion principle that every Fermion carries a unique ID number while the whole explanation is more complicated. I haven't read Damasio's book and don't really know enough of this theory to create this article. This emergent process occurs when an organism becomes It doesn’t make a difference then, if you think of physiology acting like the thermostat in your house, i.e. How and from what is our experience of color produced, for example? Thanks for adding to my reading list…but with all due respect, there is no homeostasis in physiology, only balanced equilibrium. The CDRegions interlink with each other, but the linking appears to converge heavily in a region Damasio calls the PMCs (posteromedial cortices), an unusual name referring to a region that, judging by his diagrams, appear to be in the middle portions of the parietal lobe, and the posterior cingulate cortex underneath. Damasio's definition of emotion is that of an unconscious The lower portions of the brainstem are focused on the viscera: the heart, digestive tract, etc. knowing a feeling. a donut), which is just a theory about the software and hardware of the brain. If this happens repeatedly, or perhaps once with strong emotions firing, synapses become strengthened. The multisensory doughnut example above would be a fairly high level CDZ. Three important concepts in this theory are 'emotion', 'feeling' and 'feeling a feeling' (or core consciousness). Biology always seems to be an improvisation, although it’s improvisation honed by natural selection across millions of generations. Developed in his (1999) book, The Feeling of What Happens, Antonio Damasio's three layered theory of consciousness is based on a hierarchy of stages, with each stage building upon the last. Multiple brain areas are required for the Protoself to function. This paper contributes an analysis and formalization of Damasio's theory on core consciousness. One possible answer along these lines is Michael Graziano’s Attention Schema Theory, which I’ve addressed it other posts: https://selfawarepatterns.com/2014/10/16/the-attention-schema-theory-of-consciousness-deserves-your-attention/ And here we get to what I find to be the most interesting aspects of Damasio’s theory. I know that even my own fascination with the hard problem itself comes from the deterministic and unconscious atoms that bounce around my skull, but I’m still not sure if I can ever be certain that I’m not the only person who’s really alive. That said, I’d imagine you can find ‘The Feeling…’ online somewhere; Amazon shows used hardcovers from 1 cent up. Wouldn’t you say it is true that every aspect of life is rooted in physics and chemistry that life bootstrapped upon? So the smell of doughnuts may trigger memories of the sight and taste of doughnuts. Too often it seems to get relegated in favour of language (symbolism) and algorithmic computation as preconditions. Damasio's Theory of Consciousness Proto-Self The most basic representation of self(awareness shared by all life forms) Pre-conscious state-concerned only with homeostasis Direct report of body's response to environment Provides reference for 'Core Consciousness' and Extended without its predecessors, and, unlike them, requires a vast use of This  happens with greater resolution in the neocortex than in the sub-cortical areas, but it happens in many areas of the brain, all in the regions closest to where the sensory pathways come in. Two, definition of ‘consciousness’: I’ve read a couple more of your posts on consciousness, and I think I see where you’re coming from. My favorite philosopher of mind is David Chalmers, who makes a distinction between the hard problem and the easy problem of consciousness: the easy problem being “how does the mind work”, and the hard problem being “why is a mind conscious”. Why Do You Remember The Past But Not The Future? My personal experience is that most won’t, which is why I gave my initial answer above. Damasio envisions CDZs existing in the “many thousands”, but there being a few dozen CDRegions. Later, when only one of these signals come in, it may trigger a reverse signal flow, initiating a process called retroactivation, that causes a version of the patterns that initially formed the convergence to reappear in the image areas. Based on that review (thanks! emotion manifest as mental images, or brain movies. He makes a distinction that had never occurred to me, the one between having an emotion, and the feeling of the emotion. CDZs exist in hierarchies. The brainstem is heavily involved in generating the core self, but it isn’t the main show. I agree that studying the mechanisms of the brain is much more interesting and fruitful than pondering the hard problem, but I still think that the problem exists. Evolution had no such incentive to do that with brains. But CDZs aren’t just for generating images. Damasio makes no pretense of his theories being the final word, only that they add possible explanations of what is happening, and I think they definitely do that. working to maintain a certain status quo. A feeling arises when the organism becomes aware of the I’ve never seriously considered the possibility that other people are zombies, but I just don’t see any way to explain my own experiential reality in purely physical terms. It’s worth watching some Demasio videos – on one he actually says he things homeostasis is not a helpful word coz it implies static which the system is anything but. Homeostasis and balanced equilibrium. This occurs when the patterns contributing to But it is hard to explain pathophysiology in terms of the thermostat model. Further down, they give a medical definition: “the maintenance of relatively stable internal physiological conditions (as body temperature or the pH of blood) in higher animals under fluctuating environmental conditions; also : the process of maintaining a stable psychological state in the individual under varying psychological pressures or stable social conditions in a group under varying social, environmental, or political factors”, http://www.merriam-webster.com/dictionary/homeostasis. These brain areas work together to Here are my paraphrases: There’s obviously a lot here, and I’ve just given a very surface level summary. Excellent overview and thanks for the reminder – his ‘The Feeling of What Happens’ is still on my list – speaking of which, and with hindsight – I think I wish I’d read prior to ‘Self Comes …’, https://www.nytimes.com/books/99/10/24/reviews/991024.24calvint.html. It doesn’t seem to address the difference between what happens in our conscious experience and what happens subconsciously, or of the experience of experience. In Damasio (1999) the neurologist Antonio Damasio puts forward his theory of consciousness. I think you might be overstating the role of the brainstem, at least in Damasio’s theories. He describes his theory in an informal manner, and supports it by evidence from neurological practice. This survival impulse is shared by all life, even the simplest single celled organisms. representative images, based on communications received from the Enter your email address to follow this blog and receive notifications of new posts by email. The answer is that it doesn’t. Damasio's approach to explaining the development of consciousness relies on three notions: emotion, feeling, and feeling a feeling. Further from the sensory pathway areas are the dispositional portions. When something triggers an emotion, it happens. The image of a doughnut may come in at the same time as the smell of doughnuts and then the taste. But as it plays, the conductor comes into existence and then takes control of the symphony. Change ), You are commenting using your Twitter account. Like keithnoback’s comment. But, at least, we should try. A relationship is Thanks Liam. In other words, they aren’t us minus the intelligence. . The image of the bear that probably popped in your mind while reading the previous sentence was, according to Damasio, recreated from the bear related CDZs in your brain being triggered by the word “bear.”. Thanks for your thoughts. patterns develop into mental images, which then float into the To begin with, Damasio describes two types of brain areas: image making areas, and dispositional areas. Learn how your comment data is processed. Three important concepts in this theory are ‘emotion’, ‘feeling’ and ‘feeling a feeling’ (or core consciousness). The same neurological stories mentioned in the review are in ‘Self…’. this 'self' is to constantly detect and record, moment by moment, the Is the singularity right around the corner? The relationship between usefulness and falsifiability, Follow SelfAwarePatterns on WordPress.com. This is the most basic level of And those troubled by it will likely never find explanations about simplistic internal models satisfying, which is what keeps leading me to the conclusion that we’ll never “solve” the hard problem, only explain it. Developed in his (1999) book, The Feeling of What Happens, Antonio Damasio's three layered theory of consciousness is based on a hierarchy of stages, with each stage building upon the last. as Damasio dubs it, is the Protoself. Three important concepts in this theory are 'emotion', 'feeling' and 'feeling a feeling' (or core consciousness). Sufficient condition: the ability to distinguish self from others. From the brainstem arise primordial feelings. So, their implementations can be different via different machines. Three, many other animals have similar brain stem like human’s; that is, other animals also have consciousness although not as sharp as ours. But that strikes me as being chauvinistic against alternate forms of consciousness. I’ve recently started hearing the word “allostasis” as a substitute for “homeostasis”.
