Sir Alan Hodgkin
(5 Feb 1914 - 20 Dec 1998)

English physiologist and biophysicist.


Science Quotes by Sir Alan Hodgkin (4 quotes)

Nervous messages are invariably associated with an electrical change known as the action potential. This potential is generally believed to arise at a membrane which is situated between the axoplasm and the external medium. If this theory is correct, it should be possible to record the action potential between an electrode inside a nerve fibre and the conducting fluid outside it. Most nerve fibres are too small for this to be tested directly, but we have recently succeeded in inserting micro-electrodes into the giant axons of squids (Loligo forbesi).
Co-author with Andrew Aelding Huxley, British physiologist, (1917- ).

'Action Potentials Recorded from Inside a Nerve Fibre', Nature (1939), 144, 710.
Science quotes on:  |  Nerve (60)

One of the many useful properties of giant nerve fibres is that samples of protoplasm or axoplasm as it is usually called can be obtained by squeezing out the contents from a cut end … As in many other cells there is a high concentration of potassium ions and relatively low concentration of sodium and chloride ions. This is the reverse of the situation in the animals’ blood or in sea water, where sodium and chloride are the dominant ions and potassium is relatively dilute.
— Sir Alan Hodgkin

The zoologist is delighted by the differences between animals, whereas the physiologist would like all animals to work in fundamentally the same way.

[William Rushton was] a man with great personal magnetism and considerable charm… [although] There were those who misjudged all of this as arrogance.
— Sir Alan Hodgkin
In obituary, 'Some Recollections of William Rushton and his Contributions to Neurophysiology', Vision Research (1982), 22, 614.

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
