Electroencephalograph' Activity after
- A. Jacobson
(1963) remarked in what remains a classic study of sleep and wakefulness, ithere are more books and articles devoted entirely, or mainly, to the discussion of insomnia than to any other trouble connected with sleep, but they are for 'the most part to? general to comment upon. ti Goethe wrote : ' should be glad if, when people come to a clear Uriderstanding in natural science, they would stick to truth, and not go transcendent again after all has been done in the region of the comprehensible". (Conversations). A great deal of work has been done on sleep in recent years, in centres all over the world, on man and on animals, and from the standpoint of different disciplines. I shall try to summarise some of this work which seems to me interesting and relevant to the subject of insomnia.
