Characterizations of terahertz wave of transfer of nerve impulse along the nerve fibre cells in the life systems

We investigated first the form and features of the action electro-potential on the nerve-cell membranes, which are directly cognate to the non uniformity of distribution of sodium ions and potassium ions between the inner and exterior of cell-membranes as well as their properties of forms of kineticism under the affection of an electro-information. However, the action electro-potential, in essence, is only a static impulse; it cannot propagate along the nerve organizations. But, if the nerve organizations are acted by the bio-energy, which could lead to the periodic variation of the sodium ions and potassium ions in the inner and exterior of the never cell membranes can be varied periodically under the action of bio-energy by virtue of the works of sodium pump and potassium pump on the surface of membrane of cells, then the nerve impulse can propagate along the nerve fiber cell membranes. Our investigations verify that the bio-energy relinquished from the hydrolyses reaction of adenosine phosphate (ATP)molecules in the cells can play the role, it relinquished the bio-energy of o.42 evV can be conveyed by the protein molecules to these sodium pump and potassium pump to work, thus the propagation of the nerve impulse can be carried out automatically in living systems. This is just the mechanism of propagation of the nerve impulse along the nerve cell membrane. This designates that the energy relinquished from the hydrolyses reaction of adenosine phosphate (ATP) molecules controlled the propagation of the nerve impulse. Because ATP molecules are often affixed on the protein molecules, where the energy is conveyed along the protein molecules from the position of generation of hydrolys reaction to the position utilized the energy in virtue of convey of the soliton composed by the excitons through the mechanism of self-trapping, where the exciton is aquantum engendered by the C=0 stretching (or amide-I) vibrations. We studied and obtained the properties of convey of bio-energy, which is carried by Pang’ssoliton, along α-helical protein molecules and found further the lifetimes of Pang’soliton, which is between 0.53×10-10S 0.65×10-10S at physiological temperatureT=300K. In this lifetime Pang’s soliton can peregrinate over several hundreds of amino acid residues. This implicatively insinuates that Pang ‘s theory is a germane and redress theory of bio-energy convey, then Pang’s soliton is a genuine carrier of bio-energy convey in protein molecules. If the bioenergy was conveyed into the nerve membrane to drive the works of sodium pump and potassium pump, then the transfer of nerve impulse along the nerve membranes can be carried out. So, we can verbally express that there is not the convey of nerve impulse without the works of sodium pump and potassium pump, or the bio-energy. This betokens that the nerve impulse can be conveyed along the nerve membrane, only if the bio-energy was provided and was absorbed genuinely by the sodium pump and potassium pump. In order to compose a stable propagation of nerve impulse, then its times composing must be shorter than the lifetime of Pang’s soliton or its experimental values, or else, the nerve impulse is not stable and is nugatory. Thus we can affirm that the nerve impulse is a terahertz wave. Thus we can affirm and verified that the nerve impulse can be convey along the nerve systems in the terahertz wave, instead the millimeter wave. We determinate and discuss further its features. This is first time to determinate the terahertz features of convey of the nerve impulse along the nerve fibers in life systems, which will promote great the development of the nerve science.
