Thus, we conclude that thermonuclear reactions are the main
source of energy in the sun and in the stars. 27. J.S. Zaveri, Human Body : Design, Function and Development, page
57
“The nervous system is the most complex system in the human body. It co-ordinates and controls the work of other systems (of the body)
and through them controls the function of the body as a whole". 28. (a) Ibid., p. 75–
"The neuron is the structural and functional unit of the nervous system. It is an electrically charged cell, specialized in two key areas of functions: excitability and conductivity." J.S. Zaveri & Muni Mahendra Kumar, Neuroscience and Karma, pages 26, 27“The miraculous functions that brains perform depend on the power of nerve-cells to produce certain electrical and chemical changes. ... There is an electrical potential difference of nearly 1/10 of a Volt between the inside and outside of the nerve-fibre. Similar voltages across the surfaces of all our millions of nervecells provide the means by which messages are sent and decisions made in the nervous system. Each nerve-fibre is a charged system, it has a source of energy available to allow the propagation of messages. If the fibre is strongly stimulated, a sort of electrical explosion spreads all the way along its whole length. This is the nerve-impulse which is the signal that travels along nerve-fibres." Ibid., page xix“Every second, 100 millions messages bombard the brain carrying information from the body's senses. A few hundred, at most, are permitted through to brain regions above the
brainstem. Of these, the concious mind heeds a few." (d) Ibid., page xxi
“Much of our knowledge stems from electric stimulation of the
brain or ESB.' (e) Ibid., page 3 –
"Today several disciplines are involved in the study and research of brain and its functions. Physiologists record and study its electrical responses."
