'''Alpha waves''' are [[Electromagnetic radiation|electromagnetic]] oscillations in the frequency range of 8–12 [[Hertz|Hz]] arising from ''synchronous'' and ''coherent'' (''in phase'' / ''constructive'') electrical activity of [[Human thalamus|thalamic]] pacemaker cells in humans(contracted; show full)ythm. Alpha waves are observed when a patient is awake and resting with eyes closed, and in some kinds of sleep and reversible coma. True, the Jell-O waves are a little slower and of much lower amplitude, barely within normal human limits, but that doesn't tell you much by itself. Hypoxia, encephalitis, and other medical conditions can cause reduced frequency and amplitude, as can drug use.

March 17, 1993, technicians at St. Jerome hospital in Batavia test a bowl of lime Jell-O with an EEG machine and confirm the earlier testing by Canadian Doctor Adrian Upton in 1969 that a dome of wiggly Jell-O has brain waves identical to those of adult men and women. In 1969, Dr. Upton connected an electroencephalograph (EEG) to a dome of lime Jell-O, only to find the readings to be almost identical to those of healthy human beings.⏎
