higher races of man, more intensively in children than in 

 adults. 



We have stated that the power of an animal is executed 

 solely by the brain. The constant oxidation is due to the 

 thyroid influence, but the thyroid gland alone does not 

 produce emergency energy. The adrenal-sympathetic sys- 

 tem, in collaboration with the thyroid gland, governs the 

 outburst of energy in attack or escape and in the expression 

 of the emotions. 



In the infinitely delicate white matter, or matrix, of the 

 brain, physical conductance paths of microscopic dimen- 

 sions are established by electric charges as they pass through 

 the matrix. These molecular paths of conductance become 

 facilitated with the repeated passage of electric currents 

 that are generated in the cells of the gray matter of the 

 brain which is stimulated by the sense organs. 



Could this network of facilitated pathways in the matrix 

 of the white matter be detected by an infinitely powerful 

 microscope, a single brain might exhibit a number of 

 " hookups'* comparable to the telephone wires, exchanges, 

 and receivers in a great city. Could one look with an eye of 

 infinite magnification into the recording matrix of the brain 

 of an animal, one could therein read the configuration of its 

 multitude of action patterns, that is, one could read every 

 act, every experience of that animal, from the moment of its 

 birth. This is the mechanism of memory, reason, and 

 imagination, or "mind," in man and animals. 



But within this plastic and passive matrix on which the 

 special senses have caused to be etched this network of 

 conducting pathways of action, no power is generated 

 by which its intricate system can be operated. It is in 

 the cells of the gray matter of the brain that the energy 

 required to operate this system is generated. 



Since the only energy available to the animal is that 

 which the animal captures in the form of food from the plant
