ABSTRACT
This chapter considers another major theoretical movement that attacks the problem from a totally different direction and at a totally different scale of magnification. The Neuron Doctrine is universally accepted now. It states a fundamental truth about the anatomy of the brain and its components; that truth is that the brain, like all of the other organs of the body, is composed of an assemblage of isolatable cells or neurons, each of which is separated from its neighbors by a semipermeable and continuous cell membrane. The classic and currently fully accepted Neuron Doctrine is a very specific statement about the anatomy and physiology of neurons. To summarize, the Neuron Doctrine can be distinguished from the neuron doctrine and both can be distinguished from—the single neuron theory. Traditional neurophysiology up until the 1960s had largely been based on the assumption that the energy of a stimulus was the sole determinant of its response.
