Nervous System Quotes (7 quotes)

I can say, if I like, that social insects behave like the working parts of an immense central nervous system: the termite colony is an enormous brain on millions of legs; the individual termite is a mobile neurone.
In Late Night Thoughts on Listening to Mahler's Ninth Symphony(1984), 224. Note: Spelling “neurone&rdwuo; [sic].

I propose to substitute the word 'autonomic'. The word implies a certain degree of independent action, but exercised under control of a higher power. The 'autonomic' nervous system means the nervous system of the glands and of the involuntary muscle; it governs the 'organic' functions of the body.
'On the Union of Cranial Autonomic (Visceral) Fibres w;th the Nerve Cells of the Superior Cervical Ganglion', The Journal of Physiology, 1898-99, 23, 241.

Men are noisy, narrow-band devices, but their nervous systems have very many parallel and simultaneously active channels. Relative to men, computing machines are very fast and very accurate, but they are constrained to perform only one or a few elementary operations at a time. Men are flexible, capable of “programming themselves contingently” on the basis of newly received information. Computing machines are single-minded, constrained by their “pre-programming.”
From article 'Man-Computer Symbiosis', in IRE Transactions on Human Factors in Electronics (Mar 1960), Vol. HFE-1, 4-11.

The role of inhibition in the working of the central nervous system has proved to be more and more extensive and more and more fundamental as experiment has advanced in examining it. Reflex inhibition can no longer be regarded merely as a factor specially developed for dealing with the antagonism of opponent muscles acting at various hinge-joints. Its role as a coordinative factor comprises that, and goes beyond that. In the working of the central nervous machinery inhibition seems as ubiquitous and as frequent as is excitation itself. The whole quantitative grading of the operations of the spinal cord and brain appears to rest upon mutual interaction between the two central processes 'excitation' and 'inhibition', the one no less important than the other. For example, no operation can be more important as a basis of coordination for a motor act than adjustment of the quantity of contraction, e.g. of the number of motor units employed and the intensity of their individual tetanic activity. This now appears as the outcome of nice co-adjustment of excitation and inhibition upon each of all the individual units which cooperate in the act.
Inhibition as a Coordinative Factor', Nobel Lecture (12 Dec 1932). Nobel Lectures: Physiology or Medicine 1922-1941 (1965), 288.

This integrative action in virtue of which the nervous system unifies from separate organs an animal possessing solidarity, an individual, is the problem before us.
The Integrative Action of the Nervous System (1906), 2.
Science quotes on:  |  Action (52)  |  Animal (138)  |  Individual (54)  |  Integration (10)  |  Organ (39)  |  Possession (24)  |  Problem (178)  |  Separate (8)  |  Unification (5)  |  Virtue (27)

With the nervous system intact the reactions of the various parts of that system, the 'simple reflexes', are ever combined into great unitary harmonies, actions which in their sequence one upon another constitute in their continuity what may be termed the 'behaviour'.
The Integrative Action of the Nervous System (1906), 237.
Science quotes on:  |  Behavior (10)  |  Reaction (47)  |  Reflex (8)  |  Sequence (15)

Worry affects circulation, the heart, the glands, the whole nervous system, and profoundly affects the heart. I have never known a man who died from overwork, but many who died from doubt.
Leonard Louis Levinson, Bartlett's Unfamiliar Quotations (1972). Cited in Bill Swainson, Encarta Book of Quotations (2000), 624.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan

The Simpsons and their Mathematical Secrets,
by Simon Singh

Cleverly embedded in many Simpsons plots are subtle references to mathematics, because the show's brilliant comedy writers with advanced degrees in math or science. Singh offers an entirely new insight into the most successful show in television history.
