Recent studies of hemoglobin have indicated the probability that the
once overlooked noxious nitric oxide may have been at the very beginning
of molecular evolution.
Long considered a "second" neural messenger system -this pervasive gas
permeates cell walls with quantum like simultaneous speed. In it's many
roles it acts as an all purpose messenger system.
It is a feedback regulator, transmittance coordinator, plus being an
antimicrobial defense system, neonatal axonial segregator,and vascular
switch controller.
As such it presents us with a simpler and more basic possibility of
understanding the workings of complex sensory and cognitive functions.
