Splitting: with an another person added , a copy of this
experience is sent to the ‚world outside‘
Inversion: as ‚consensus‘ emerges among the community
the copy ‚outside‘ becomes the
‚real world‘ and the experience becomes the copy

Correlated with reports about perception…….
But we do not perceive parts of a scene separately !
Instead we experience the entire scene ?

• Subject – Object
• The role of the brain I
• States and transitions
• The role of the brain II
(segregation)
• Scaling from quantum to
classical
• Experience and the
Universe

Segregation at the atomic scale:
Transitions are
scaled:
and that would
allow us some
interesting
predictions……

• Scales from atomic scales to classical
scales
(a neural correspondence
problem)
AD N . for a brain with AD = 10 -15 this gives N = 1019 states
But that is another story……. Thank you for attending

a complete quantum classical transition could
take place in the brain with QM traces left
behind as ‚experiential entities‘

Ion channel proteins are the quantum-classical transition
devices:
• filter ‚gating‘ = ion – oxygen
coordination states change:
characteristic time: 10-12 sec
Action = E.t = 1kT . 10-12
= 4.10-21J . 10-12 s = 10-33 Js
Intra-molecular transitions:
within one molecule (e.g KcsA
ion channel)
filter
cavity
pore gate
Voltage
sensor

Coherence dynamics couples the
filter states with the pore gate state

High affinity or ‚trapped‘ state
Ion 1: 1(1,2) = S1 + S2
Ion 2: 2 (3,4) = S3 + S4
System (ion) states:

NCC: How could it work ?
• Scales
filter ‚gating‘ = ion affinity states
time: 10-12 sec
A = E.t = 1kT . 10-12 = 4.10-21J . 10-12 s = 10-33 Js

Physical Action – dimensional analysis –QM principally applies whenever
a) the physical ‚action‘ is instantiated at thequantum scale of ħ (h bar, = h/2 ) which is roughly
10-34 kg m2 s-1
the atomic scale :
eg Action : = Length . momentum
L . (M.L)/t = M. L2 t-1
eg. Action: = Energy . Time = E . t
