OK, lets get serious. Published journal articles please (rather than
non-reviewed web sites) to show the neural basis (and I mean in terms of
neurons, synapses and neurotransmitters) of 'redundant parallel nerve fibres
holding a concept'. I mean, what is your proof of any of this? Are abstract
conceptual fibres pyramidal cells? Granule cells? Interneurons? Basket cells?
Purkinje cells? What? And by the way, I'm uncertain of your use of redundant,
since you seem to be suggesting that actually they aren't redundant but very
useful!

Again, prove it. There's a number of suggestions that people don't think in
language (see Pinker for a start), but in a kind of mentalese. This would
seems to suggest that the auditory system does not hear itself think an idea
(for a start the _auditory_ system responds to external sounds, not to
subvocal speech - have a look through some functional imaging studies.).

  Or be both! Or alternatively, give up on Mentifex and get on with some
serious research
