In brief as I understand it, these sort of sensations are due to synapses occurring where the insulation aspect in cell walls have thinned to the extent that neighbouring cells are effected by an overload or a more powerful synapse due to 'bottle necking' as I describe in DPS http://sites.google.com/site/beauxreflets/dps
My neurologist prescribed Azilect to assist and guard against events described as 'popping type sensations'.
I also take Coconut Oil on a regular basis as I understand and benefit from its medium-chain fatty acids or medium-chain triglycerides (MCT)as they are known. It certainly appears to assist in maintaining the cell wall insulation properties. And I wish this oil was on the prescription list as a medicine, as it is quite expensive.
I hope this helps.
