Actually, that is a very probable mechanism - of course not the only
one. NO is highly diffusible and hydrophil, so it passes through cell
membranes with "little to no resistance".
There are a number of systems where NO is being attributed an
increasingly important role. I am especially aware of the implications
concerning the cerebellum, which causes a slightly biased list of
papers, which I would recommend as a good start, but here goes:
