A Correction
In the October 1968 issue, the article titled "Positive Spiking: A Double-Blind Control Study on Its Significance in Behavior Disorders, Both Diagnostically and Therapeutically," by Cornelius Boelhouwer, M.D., Charles E. Henry, Ph.D., and Bernard C. Glueck, Jr., M.D., contains an error in the references. Reference 7, listed on page 481 and cited on page 474, paragraph 2, should read "Hughes, J. R., Means, E. D., and Stell, B. S.: A Controlled Study on the Behavior Disorders Associated with the Positive Spike Phenomenon, Electroenceph. Clin. Neurophysiol. 18:349-353, 1965."
