Reverse Learning - Crick verbatim On The Function of REM Sleep

Crick verbatim On The Function of REM Sleep

Suppose one did not have REM, then one would mix things up. That is not necessarily a bad thing - it is the basis of fantasy, imagination, and so forth. Imagination means seeing a connection between two things that are different but which have something in common which you had not noticed before. If one had too much REM, one would predict one would be a rather prosaic person without too much imagination. But the process is not 100% efficient. If one goes on too far, one begins to wipe out everything.

Another way to look at it is to say "How could you prevent the brain being overloaded"? One way would be to make it bigger, to have more neurons. So perhaps the important thing to say is "The function of REM is to allow your brain or your cortex to be smaller".

Famous quotes containing the words function and/or sleep:

    The more books we read, the clearer it becomes that the true function of a writer is to produce a masterpiece and that no other task is of any consequence.
    Cyril Connolly (1903–1974)

    Around, the night drops swiftly down
    Its veils; does not condemn
    Or praise the different actions done.
    The hour that strikes across the town
    Caresses all and injures none
    As sleep approaches them.
    Philip Larkin (1922–1986)
