(Redirected from Alan Hodgkin)'Sir Alan Lloyd Hodgkin',
OM,
KBE,
FRS (born
February 5,
1914,
Banbury,
Oxfordshire,
England; died
December 20,
1998) was a
British physiologist and
biophysicist, who won the
1963 Nobel Prize in Physiology or Medicine for his work with
Andrew Fielding Huxley on the basis of nerve "
action potentials," the electrical impulses that enable the activity of an organism to be coordinated by a
central nervous system. Hodgkin and Huxley shared the prize that year with
John Carew Eccles, who was cited for research on
synapses. Hodgkin and Huxley's findings led the pair to hypothesize
ion channels, which were confirmed only decades later.
The experimental measurements on which the pair based their action potential theory represent one of the earliest applications of a technique of
electrophysiology known as the "
voltage clamp". The second critical element of their research was the so-called
giant axon of
Atlantic squid (''Loligo pealei''), which enabled them to record ionic currents as they would not have been able to do in almost any other
neuron, such cells being too small to study by the techniques of the time. The experiments took place at the
University of Cambridge beginning in
1935 with
frog sciatic nerve and continuing into the
1940s, after interruption by
World War II.
During the war he volunteered to work on
Aviation Medicine at
Farnborough and was subsequently transferred to the
Telecommunications Research Establishment (TRE) where he worked on the development of centimetric
radar, including the design of the
Village Inn airborne gun-laying system.
Hodgkin and Huxley subsequently published their theory in
1952.
Confirmation of ion channels came with the development of the
patch clamp, which led to a Nobel prize in
1991 to
Erwin Neher and
Bert Sakmann.
Hodgkin was educated at
Gresham's School,
Holt,
Norfolk
and
Trinity College, Cambridge. He was knighted in
1972 and appointed to the
Order of Merit
in
1973. From
1970 to
1975 he was President of the
Royal Society, and
from
1978 to
1984 he was Master of Trinity
College.
