Single Idea 5793

[filed under theme 18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts ]

Full Idea

When you get maps all over the brain signalling to each other by reentry you have what Edelman calls 'global mapping', and this allows the system not only to have perceptual categories and generalisation, but also to coordinate perception and action.

Clarification

'Reentry' is interchange of signals in the brain

Gist of Idea

Concepts and generalisations result from brain 'global mapping' by 'reentry'

Source

report of G Edelman / G Tononi (Consciousness: matter becomes imagination [2000]) by John Searle - The Mystery of Consciousness Ch.3

Book Ref

Searle,John R.: 'The Mystery of Consciousness' [Granta 1997], p.42

A Reaction

This is the nearest we have got to a proper scientific account of thought (as opposed to untested speculation about Turing machines). Something like this account must be right. A concept is a sustained process, not a static item.

The 21 ideas from G Edelman / G Tononi

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]
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]
4929 Dreams and imagery show the brain can generate awareness and meaning without input [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]
4933 Consciousness is a process, not a thing, as it maintains unity as its composition changes [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]
4934 Cultures have a common core of colour naming, based on three axes of colour pairs [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]
4941 Consciousness can create new axioms, but computers can't do that [Edelman/Tononi]
4940 Physicists see information as a measure of order, but for biologists it is symbolic exchange between animals [Edelman/Tononi]
