  John Carew Eccles - Wikipedia, the free encyclopedia
Sir John Carew Eccles (January 27, 1903–May 2, 1997) was an Australian neurophysiologist who won the 1963 Nobel Prize in Physiology or Medicine for his work on the synapse.
When Eccles passed a current into the sensory neuron in the quadriceps, the motor neuron innervating the quadricep produced a small excitatory postsynaptic potential (EPSP).
Bernard Katz and Eccles worked together on some of the experiments which elucidated the role of acetylcholine as a neurotransmitter.

John Carew Eccles was born on 27 January 1903 at Northcote, a suburb of Melbourne.
Eccles was deeply impressed by Popper's main tenet, that scientific hypotheses should be both clearly formulated and testable by experiment, and that the strength of a hypothesis depended on the failure of rigorous investigation to falsify it rather than on evidence which apparently supported it.
Eccles was awarded a Royal Medal in 1962, and the award in 1963 of the Nobel Prize in Physiology or Medicine, shared with A.L.Hodgkin and A.F.Huxley, recognized his fundamental contributions to the ionic mechanisms of synaptic transmission in the brain.

John Eccles would have been 100 on January 27th, and there will be quite a few programs on Radio National giving a detailed account of his extraordinary contribution to research and ideas.
Eccles did not last much longer either, thanks to deteriorating relations with the Board and some of the clinicians at Sydney Hospital, who simply did not understand the significance of the work being done at the Kanematsu and whose own egos found Eccles overbearing.
Eccles supported an electrical explanation which required the inhibited nerve cell’s voltage still to depolarise, that is to become less negative and move towards zero.

 John Eccles on mind and brain
Eccles feels that this 'impoverished and empty' theory fails to account for 'the wonder and mystery of the human self with its spiritual values, with its creativity, and with its uniqueness for each of us' [2].
Eccles calls the fundamental neural units of the cerebral cortex dendrons, and proposes that each of the 40 million dendrons is linked with a mental unit, or pychon, representing a unitary conscious experience.
Eccles is in basic agreement with the neo-Darwinian theory that evolution is driven by random genetic mutations followed by the weeding out of unfavorable variations by natural selection, but he also believes that 'there is a Divine Providence operating over and above the materialist happenings of biological evolution' [10].

 Mind - Chapter Six
Eccles, now retired, is considered by many of his peers to be among the world's leading neurophysiologists, and recognition of his stature came in due time when he was made Nobel laureate.
Eccles is clearly much more committed to the view that the mind or "soul" (as he now calls it) has a destiny beyond the grave for which this present life is strictly preparation.
Eccles admits that it is not yet possible to give a scientific account of the nature of this bridge, but holds that Kornhuber's experiments are presumptive experimental evidence that action can indeed be initiated by the will without the introduction of external stimuli in the chain of events leading from one to the other.

 [No title]   (Site not responding. Last check: 2007-10-18)
Eccles, drawing on his present collaborative work with the philosopher Karl Popper skows circumstantially not only the intimate connections between consciousness and specific areas of the cerebral cortex but also the unbridgeable gulf between the unique consciousness of self -- what has here been referred to as "I" -- and neurophysiological activity.
Eccles is also a member of the Pontifical Academy of Science for which in 1964 he organized a symposium on "Conscious Experience;" these papers have since been published.
Eccles, on the other hand, is, I believe, primarily concerned with meta-consciousness, the ability of a brain mechanism to focus attention on its own processing.

Eccles was proud of the fact that "the majority of the senior faculty of the newly founded Medical School at Auckland University" had been his students.
Eccles was still full of energy and ideas, but he faced the problem of a compulsory retirement age of 65, and realised that the research facilities which he required would not be available to him after 1968.
Eccles was appointed to a Distinguished Professorship in Physiology and Biophysics.

Eccles was a member of Sherrington's team investigating spinal reflexes, and also became involved in studying synaptic transmission in the heart and sympathetic ganglia.
Faced with retirement in 1968, Eccles moved to the United States in 1966, initially to Chicago and from 1968-1975 to Buffalo as Distinguished Professor of Physiology and Biophysics at the State University of New York.

However, Eccles denies that the mind is a type of nonphysical substance (as it is in Cartesian dualism), and says that it merely belongs to a different world.

Sir John Eccles has stated his feelings on the infinite potential of the human brain, and he won the Noble prize.
Such a statement that "We use all of our brain all of the time" or "It is a myth that we only use 10% of our brain" are both misleading and unhelpful uninspiring skeptical crumbs with barely a grain of truth- As well as not even being accurate statements regarding usage of the human brain.
Hence, the wisdom of intuitive folksay was correct: "The human brain is only 10% functional." John Eccles thinks that number is too high.
