- May 31 11:46 PMHi All,
Hitachi are on the verge of producing a 'personal mind reader' (?!) -

Subject: Testing Quantum Consciousness
I would like to propose a criterion for the experimental testing of
hypotheses about the ultimate brain correlate of consciousness (I am not
using the usual "NCC" anymore because the possibilities cannot be 'a
priori' restricted to neurons).
The criterion is the following: if consciousness is a properly
quantum entity, then the measurement of the activity of the ultimate
correlate in a human subject will cause a reportable effect on
phenomenal consciousness, and no other (third-person, observable)
Theorists of quantum consciousness are invited to describe
how available models could be tested according to this criterion.
My model (see previous posts) can be tested by means of
the measurement of calcium ion movements (waveforms)
in the brain, using a multilaser scanner at ultraviolet range.
It may sound like science-fiction, but this kind
of equipment - operating at the near-infrared range - will
be commercialized by Hitachi (see below). The infrared
range was chosen possibly because it is harmless and has
already been successfully compared with BOLD fMRI.
Ultraviolet can be harmful depending on the intensity.

imagine interactive campaigns that, for example, ask customers to think
positive thoughts about a certain product in exchange for discount
coupons or the chance to win a prize.
