Effects of LSD-25 on the EEG and Photic Evoked Responses
Archives of General Psychiatry April 1, 1966 E. Rodin� 30 citations
Lysergic acid diethylamide (LSD-25) reduces the amplitude of electroencephalographic (EEG) signals, causes alpha rhythms to disappear, and produces low-voltage fast or desynchronized tracings. Alpha frequencies increase by 0.5 to 4 cycles per second, with one report noting a rise from 11.6 cycles per second. These findings are based on surface and depth recordings in humans. The literature on LSD's behavioral and pathophysiological effects contains over 1,000 publications since its psychosomimetic properties were discovered in 1947.
