Hi Matt, 

Thanks for the support making clear what in the original posting
was my goal.

Is that precise? Does it mean, that one specific signal coming
from A (= input signal?) going to B (= output signal?) is anyway
identifyable on its way from A to B? - Yes, you wrote, possibly
the neuron performs some sort of operation ... on it. Does that
mean, therefore, it is not identifyable on its way?

Thanks for this explanation. That was i was looking for. (I am not
a professional at neuroscience.)
