Dear Syed
According to my mathematics called self-field theory (SFT) there may be two different methods of storing memories: one is based on electromagnetic (EM) fields while long term memories are stored as strong nuclear (SN) fields, probably within DNA. The conversion of short and long term memories presumably happens during 'deep' sleep when the two dimensional, EM fields are somehow converted into three-dimensional gluon encoded data within quarks. This is implied by the structure of the mathematics and its connections to particle physics.
The mathematics
If this hypothesis is correct the question is what happens to 'sound' in long term memories?
Could this be useful in your research into consciousness?
