The behavior of an organism is the result of functioning of organic structures. Practice modifies behavior. It is not unreasonable to expect, then, that practice also modifies the structures responsible for the behavior.
In recent years, the metabolism of the nerve impulse has received much attention from neurophysiologists. This is particularly true of those workers who adhere to the theory of chemical meditation, which arose out of the discovery that an ester, acetylcholine, is liberated at the synapses and myoneural junctions within the parasympathetic system. As a result of this interest, today there is much evidence that acetylcholine is closely associated with the nerve impulse, not only in the parasympathetic division, but also throughout the central nervous system.
