TGD and EEG
Note: Newest contributions are at the top!
In the previous posting I described the God helmet experiments of Persinger briefly and Persinger's own interpretation of the results. Anyone interested to understand what neurotheology is about should listen the fantastic talk God and the Brain - The Persinger 'God Helmet', The Brain, and visions of God by Todd Murphy.
In this posting I will discuss the TGD inspired interpretation of the results of Persinger's experiments. To put it in very concise manner: whereas Persinger interprets right brain as the "visitor" explaining sense of presence experiences and even experiences in which subject meets God or light being, I identify the "visitor" of the visitor experiences as the personal magnetic body or in the case of enlightment experiences as the emergence of a new layer to its fractal structure. Magnetic body would be also responsible for the third person aspect of conscious experience, which means that we are able to see ourselves from bird's eye perspective. Magnetic bodies make as social animals, and are responsible for the cultural evolution and explain why we differ so much from our cousins although the genomes differ so little. EEG and its fractal generalizations provide a universal communication and control tool for magnetic body so that it can use biological body as sensory receptor and motor instrument.
1. Frequency modulation as a "code of consciousness"
Maxwell's electrodynamics would suggest that a superposition of endogenous and external magnetic fields takes place in God helmet experimens and is partially responsible for the effects. This is clear from the fact that quite spesific magnetic stimulation is used (signals derived from EEG during the second stage). In TGD framework one should be able to interpret this.
2. The basic philosophy behind the TGD based model
The basic philosophy behind the TGD based explanation of God helmet experiences differs in many respects from that behind the model of Persinger and Murphys. Therefore it is good to describe this philosophy first.
Consider now the more technical assumptions.
3. The model for God helmet experiences
Consider now a the general TGD inspired model explaining God helmet experiences.

Anyone - atheist or believer - wanting to learn about Persinger's work and the basic insights of neuro-theology should listen the extremely inspiring talk God and the Brain - The Persinger 'God Helmet', The Brain, and visions of God by Todd Murphy. Persinger's work (for references to the articles by Persinger and collaborators see the Wikipedia article about God helmet) suggests that the temporal pattern of the modulation of magnetic field strength (FM would be in question for slow variations) is important. We do not however know the "code". Also the strength of the magnetic field can be important. Note that the effects of very weak ELF em fields on vertebrate brain take place in amplitude windows.
The modulation of magnetic field would probably induce FM of cyclotron frequencies. The model for hearing suggests this kind of modulation as a manner to represents the frequencies of the sound wave. Also phase information is very important: time reversed speech sounds very different as normal speech but has the same power spectrum. Modulations would be slow in the time scales defined by the audible frequency range. .1 seconds would represent lower limit for the variation rate of modulation. Audible frequencies above 20 Hz.
1. God helmet
God helmet or Koren helmet named after its inventor is the device used by Persinger and collaborators to study the effects of magnetic field on consciousness. Transcranial magnetic stimulation is not in question: TCMS uses fields of order Tesla whereas Persinger uses magnetic fields with strength of order .01 Gauss. This is 2 per cent of the nominal value of Earth's magnetic field. There is a coil above both temporal lobes and the active coil rotates counterclockwise.
2. Persinger's experiments and cyclotron frequencies
A more quantitative description of the God helmet experiment assuming that cyclotron frequencies are essential goes as follows.
3. Persinger's explanation
Persinger's own explanation for the findings relies on what might be called neurotheology.
Consider now the explanation of the experiences induced by God helmet. The lecture by Todd Murphy helps considerably in attempts to understand the gist of the explanation and also helsp to see its problematic aspects.
Somehow my personal feeling is that this model is not quite correct. For instance, I do not understand the meaning "intrusion"? This could be of course be just my misunderstanding. Also the hypothesis about the specialization of left and right amygdala looks strange. In the next blurb I will describe the TGD inspired interpretation of Persinger's findings.

In TGD Universe gauge fields are replaced with topological field quanta. Examples are topological light rays, magnetic/electric flux tubes and sheets, and flux quanta carrying both magnetic and electric fields. Flux quanta form a fractal hierarchy in the sense that there are flux quanta inside flux quanta. It is natural to assume quantization of Kähler magnetic flux. Braiding and reconnection are the basic topological operations for flux quanta.
The basic question is how the basic notions assigned with the classical gauge and gravitational fields understood in standard sense generalize in TGD framework.
