If we want to better understand how the microtubules can translate and input the
information carried by the electrophysiologic impulses that enter the brain cortex,
a detailed investigation of the local electromagnetic field structure is needed. In
this paper are assessed the electric and the magnetic field strengths in different
neuronal compartments. The calculated results are verified via experimental data
comparison. It is shown that the magnetic field is too weak to input information to
microtubules and no Hall effect, respectively QHE is realistic. Local magnetic flux
density is less than 1/300 of the Earth’s magnetic field that’s why any magnetic
signal will be suffocated by the surrounding noise. In contrast the electric field
carries biologically important information and acts upon voltage-gated
transmembrane ion channels that control the neuronal action potential. If mind is
linked to subneuronal processing of information in the brain microtubules then
microtubule interaction with the local electric field, as input source of information
is crucial. The intensity of the electric field is estimated to be 10V/m inside the
neuronal cytoplasm however the details of the tubulin-electric field interaction are
still unknown. A novel hypothesis stressing on the tubulin C-termini intraneuronal
function is presented replacing the current flawed models (Tuszynski 2003,
Mershin 2003, Hameroff 2003, Porter 2003) presented at the Quantum Mind II
Conference held at Tucson, Arizona, 15-19 March 2003, that are shown in this
presentation to be biologically and physically inconsistent.
