My conjuncture is that the natures of sympathetic and parasympathetic action potentials are different. My findings propose me that

  • sympathetic action potential is little longer lasting than parasympathetic
    • there may be another mechanism in sympathetic action potential - some sort of plateau phase which does not exist in parasympathetic action potential
    • however, I have not managed to gather any convincing evidence on this claim
  • parasympathetic action potential has greater energy per one time instance, while the energy of sympathetic AP is distributed along wider time space

My hypothesis is that the energy of parasympathetic and sympathetic action potentials is equal. This would suggest me that the action potentials of the autonomic nervous system are coming from the same source. Their nature is just different. What can this source be exactly?

I have read the recent Physiology and Pathophysiology books where this topic was not covered rigorously. I did not manage to find any good publication about the topic, probably, I missed something.

What is the nature of autonomic nervous system action potentials? You can select what ever condition you want and see if you can get some findings as I have got.

What makes you say the action potentials are different? From my knowledge APs are uniform across all nerves –  AndroidPenguin Apr 22 at 21:30
    
See the energy spectrum of APs. You have to define uniform. They seem to have the same energy (uniform; thing which has confused people to think that they are uniform also in nature), but different energy spectrums. –  Masi Apr 23 at 7:45
