Lesson 19-2 The stuff of dreams

If it is not a question of resting the body, then perhaps it is the brain that needs

resting? This might be a plausible hypothesis were it not for two factors. First the

electroencephalograph (which is simply a device for recording the electrical activity of

the brain by attaching electrodes to the scalp) shows that while there is a change in the

pattern of activity during sleep, there is no evidence that the total amount of activity is

any less. The second factor is more interesting and more fundamental. Some years ago

an American psychiatrist named William Dement published experiments dealing with

the recording of eye-movements during sleep.
