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

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'.
| 12601 | The way things look is a relational matter, not an intrinsic matter [Harman] |
| 7387 | "Qualia" can be replaced by complex dispositional brain states [Dennett] |
| 7658 | Obviously there can't be a functional anaylsis of qualia if they are defined by intrinsic properties [Dennett] |
| 2582 | A brain looks no more likely than anything else to cause qualia [Block] |
| 7521 | It is question-begging to assume that qualia are totally simple, hence irreducible [Churchlands] |
| 7523 | The qualia Hard Problem is easy, in comparison with the co-ordination of mental states [Churchlands] |
| 3226 | Are qualia irrelevant to explaining the mind? [Rey] |
| 6546 | Pain is composed of urges, desires, impulses etc, at different levels of abstraction [Lycan] |
| 6547 | The right 'level' for qualia is uncertain, though top (behaviourism) and bottom (particles) are false [Lycan] |
| 4090 | Weak intentionalism says qualia are extra properties; strong intentionalism says they are intentional [Crane] |
| 7706 | If qualia supervene on intentional states, then intentional states are explanatorily fundamental [Jacquette] |
| 7011 | Qualia are not extra appendages, but intrinsic ingredients of material states and processes [Heil] |
