It is traditionally believed that cerebral activation (the presence of low voltage fast electrical activity in the neocortex and rhythmical slow activity in the hippocampus) is correlated with arousal, while deactivation (the presence of large amplitude irregular slow waves or spindles in both the neocortex and the hippocampus) is correlated with sleep or coma. However, since there are many exceptions, these generalizations have only limited validity. Activated patterns occur in normal sleep (active or paradoxical sleep) and during states of anesthesia (...) and coma. Deactivated patterns occur, at times, during normal waking, or during behavior in awake animals treated with atropinic drugs. Also, the fact that patterns characteristic of sleep, arousal, and waking behavior continue in decorticate animals indicates that reticulo-cortical mechanisms are not essential for these aspects of behavior.

Nature has been viewed as a curative for the problems of urbanized society, and primitivism has been forwarded as a viable alternative to modification of the industrial world. Critical theory maintains that the current phase of social development tends toward 'total administration', and that escapes to nature are them selves administered and controlled by the larger society. Back-to-nature is critiqued as an unproductive strategy whose middle-class origins render it élitist.

Of Aristophanes' comedy Αολοσκων we have only seventeen fragments, not extensive enough to allow us an accurate judgment about the contents; but it seems certain that the second performance of the play belongs to the so-called Middle Comedy, and the various fragments are well explained in the beautiful edition of Blaydes. I will add only some words about the title.
