They were experimenting with this at the Naval ship yard in Philadlphia in the mid to late 60's. They were using it on clerk-typists. This fried the medial lobe in more than a few of the (unwitting) test subjects. They became schizophrenics, with a limp in one leg.. .you can find them walking around philadelphia, all with the limp, all former clerk-typists, all now gray-headed, and all cursing the same voices: Germans, Jews, and (as they say,not me) "those damn niggers." Also, all the ones I ran into were African American. (Sorry if anyone offended, just being accurate, not working to spread hate.Peace.)
