thanks for that info ... i was going to ask for the Cliff notes version, and there it is.
I guess it could also be seen as a testament to how interesting a topic it is
SF I think I understand your points a little more clearly now, cheers for clearing things up. I guess then these two realities are very seperate; the internal dies with you and is intrinsic to you but the secondary, external reality is independent right? So that is to say that your perception of reality is just as real as reality itself which... yeah I can grasp that
As for the corpuscle, it has two definitive states: "On" or "Off", that is to say it is either generating a chemical potential to initiate a neuron impulse or it is not. These two states or physically different, with the "on" state requiring some kind of pressure to compress the membrane layers:
So you can see the layers of membrane, they are filled with a pressure sensitive protein. If no pressure is applied, you do not feel anything. The more pressure applied, the more membranes affected so the greater the sensation. Essentially, a stimulus external to yourself is required for any signal to be generated in the first place.
