Electroencephalographic Abnormalities in Endocrine Disease

Abstract
THE intimate metabolic processes of the brain are closely related to the general metabolism of the body, and the electric activity of the brain varies with certain endocrine functions. Lindsley and Rubenstein1 showed a correlation between the alpha frequency and the metabolic rate. Gibbs and Gibbs2 demonstrated changes in the cortical frequency spectrum with the level of thyroid function. Ross and Schwab3 report that when the alpha rhythm is taken during a "basal state" (with the patient fasting and resting for half an hour) the correlation is not so good as when the patient is well fed, satisfied and relaxed. . . .
