Single Idea 4935

[filed under theme 15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia ]

Full Idea

The pure sensation of red is a particular neural state identified by a point within the N-dimensional neural space defined by the integrated activity of all the group of neurons that constitute the dynamic core.

Clarification

The 'dynamic core' is the conscious part of the brain

Gist of Idea

The sensation of red is a point in neural space created by dimensions of neuronal activity

Source

G Edelman / G Tononi (Consciousness: matter becomes imagination [2000], Ch.13)

Book Ref

Edelman,G/Tononi,G: 'Consciousness: how matter becomes imagination' [Penguin 2000], p.167

A Reaction

This hardly answers the Hard Question (why experience it? why that experience?), but it is interesting to see a neuroscientist fishing for an account of qualia. He says three types of neuron firing generate the dimensions of the 'space'.

The 21 ideas from 'Consciousness: matter becomes imagination'

5793 Concepts and generalisations result from brain 'global mapping' by 'reentry' [Edelman/Tononi, by Searle]
4922 Consciousness involves interaction with persons and the world, as well as brain functions [Edelman/Tononi]
4924 A conscious human being rapidly reunifies its mind after any damage to the brain [Edelman/Tononi]
4923 The three essentials of conscious experience are privateness, unity and informativeness [Edelman/Tononi]
4925 Brains can initiate free actions before the person is aware of their own decision [Edelman/Tononi]
4926 Concepts arise when the brain maps its own activities [Edelman/Tononi]
4929 Dreams and imagery show the brain can generate awareness and meaning without input [Edelman/Tononi]
4928 Brain complexity balances segregation and integration, like a good team of specialists [Edelman/Tononi]
4927 Information-processing views of the brain assume the existence of 'information', and dubious brain codes [Edelman/Tononi]
4933 Consciousness is a process, not a thing, as it maintains unity as its composition changes [Edelman/Tononi]
4930 Consciousness arises from high speed interactions between clusters of neurons [Edelman/Tononi]
4932 A conscious state endures for about 100 milliseconds, known as the 'specious present' [Edelman/Tononi]
4931 Consciousness is a process (of neural interactions), not a location, thing, property, connectivity, or activity [Edelman/Tononi]
4934 Cultures have a common core of colour naming, based on three axes of colour pairs [Edelman/Tononi]
4935 The sensation of red is a point in neural space created by dimensions of neuronal activity [Edelman/Tononi]
4936 The self is founded on bodily awareness centred in the brain stem [Edelman/Tononi]
4937 Systems that generate a sense of value are basic to the primitive brain [Edelman/Tononi]
4939 A sense of self begins either internally, or externally through language and society [Edelman/Tononi]
4938 Prior to language, concepts are universals created by self-mapping of brain activity [Edelman/Tononi]
4940 Physicists see information as a measure of order, but for biologists it is symbolic exchange between animals [Edelman/Tononi]
4941 Consciousness can create new axioms, but computers can't do that [Edelman/Tononi]
