Andrew Fielding Huxley 1917 - 2012

چکیده
Sir Andrew Huxley (1917-2012) pioneered the physiology and biophysics of nerve conduction, skeletal muscle activation and tension generation. His ground-breaking work on nerve excitability of nerve in collaboration with Alan Hodgkin in the Cambridge Physiological Laboratory and the Plymouth Marine Biological Laboratory provided the basis for our understanding of how voltage-gated ion channels generate propagating action potentials and led to award of the 1963 Nobel Prize for Physiology and Medicine with Alan Hodgkin and Jack Eccles. Huxley then went on to perform seminal work of similar importance on muscle activation and contraction whilst at University College London. This led to the sliding filament theory and cross-bridge hypothesis of muscle contraction, completing a momentous quest within physiology, in his view, “the mechanical engineering of living things”.

Another recent surprise was the discovery of a phytoplankton bloom under the sea ice of the Arctic during investigations in the north Pacific led by Kevin Arrigo from Stanford University (Science (2012) 336, 1408). This, the authors conclude, could mean that productivity in the icy polar waters may have been underestimated by a factor of up to ten, which underlines that we still know far too li...

The offi cial date of the “birth” of the sliding fi lament theory of muscular contraction is May 22, 1954. On this day the journal Nature published two papers consecutively under the general title: “Structural Changes in Muscle During Contraction”. The fi rst paper by Andrew F. Huxley 1 and Dr. Rolf Niedergerke was entitled: “Interference microscopy of living muscle fi bres”. The second paper b...

Alan Lloyd Hodgkin and Andrew Fielding Huxley revolutionized the field of neuroscience when they provided a quantitative description of the squid axon action potential generation and propagation (Hodgkin and Huxley, 1952). The seminal article described how to recreate a biological phenomenon inside a computer using a mathematical model. Ever since, this quantitative approach has helped us in pr...
