ess of memory, reason, and imagination in man is a minor 

 one in comparison with the role of the thyroid gland; but 

 adrenalin, through its establishment of high oxidation and 

 high potential, causes to be etched a deeper action pattern, 

 hence vivid memories and a more highly facilitated pathway. 

 Although training and education are largely a collabora- 

 tion of the brain and thyroid gland, the secretion of the 

 adrenal glands so reinforces the action patterns that the 

 facilitated pathways are more quickly and more lastingly
