[00:03.88] | The stuff of dreams |
[00:12.89] | What is going on when a person experiences rapid eye-movements during sleep? |
[00:21.48] | It is fairly clear that the sleeping period must have some function, and because there is so much of it the function would seem to be important. |
[00:32.48] | Speculations about its nature have been going on for literally thousands of years, |
[00:38.80] | and one odd finding that makes the problem puzzling is that it looks very much as if sleeping is not simply a matter of giving the body a rest. |
[00:48.75] | 'Rest', in terms of muscle relaxation and so on, can be achieved by a brief period lying, or even sitting down. |
[00:58.93] | The body's tissues are self-repairing and self-restoring to a degree, and function best when more or less continuously active. |
[01:09.16] | In fact a basic amount of movement occurs during sleep which is specifically concerned with preventing muscle inactivity. |
[01:19.58] | If it is not a question of resting the body, then perhaps it is the brain that needs resting? |
[01:26.60] | This might be a plausible hypothesis were it not for two factors. |
[01:31.71] | First the electroencephalograph (which is simply a device for recording the electrical activity of the brain by attaching electrodes to the scalp) |
[01:42.12] | 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. |
[01:52.77] | The second factor is more interesting and more fundamental. |
[01:57.24] | Some years ago an American psychiatrist named William Dement published experiments dealing with the recording of eye-movements during sleep. |
[02:08.31] | He showed that the average individual's sleep cycle is punctuated with peculiar bursts of eye-movements, some drifting and slow, others jerky and rapid. |
[02:20.49] | People woken during these periods of eye-movements generally reported that they had been dreaming. |
[02:27.40] | When woken at other times they reported no dreams. |
[02:31.86] | If one group of people were disturbed from their eye-movement sleep for several nights on end, |
[02:37.64] | and another group were disturbed for an equal period of time but when they were not exhibiting eye-movements, |
[02:44.19] | the first group began to show some personality disorders while the others seemed more or less unaffected. |
[02:51.60] | The implications of all this were that it was not the disturbance of sleep that mattered, but the disturbance of dreaming. |
