Abstract

This investigation aims to provide an account of language development in terms of the brain neurochemical transmitters such as dopamine that conducts human speech mechanism using theoretical methods. Brain neurochemical transmitters are effective in language processing, so this work aims to provide an account of language development in terms of the brain neurochemical transmitters such as dopamine that conducts human speech mechanism using theoretical methods. The neurochemical structures of dopamine, epinephrine, norepinephrine, histamine and serotonin have been simulated by Monte Carlo method (MC) which uses the increased temperature to the potential energy of the neurochemicals in the brain considering the geometry optimization of the compounds as an additional conformational level.

It was suggested that dopamine can have a special impact on part of learning language by discussion of IR spectra and MC simulation through the measurement of potential energy in water by increasing the temperature. The results of dopamine nanotube pathway by running the physicochemical parameters as a practical model using Gaussian 09 program package and Multifunctional Wave-function Analyzer can approve the twisting of languagebrain due to neurochemical transmitters and nanotubes as density electron deliverers. Theoretical properties of Lagrangian kinetic energy G(r), Hamiltonian kinetic energy, Potential Energy density, Laplacian of electron density; Localized orbital locator (LOL); Local information entropy; average local ionization energy; ESP from nuclear charge; ESP from electrons and Total ESP have been calculated on the dopamine, dopamine with N jointed to BNNT and O jointed to BNNT as neurochemical transmitters.

The most stable of dopamine N or O jointed to BNNT has been approve the best optimized position for localizing the structure through delivery technique in the brain to activate the center of learning language as a simulated model. So, the best results with the calculated amounts and leads us to analyze the perspective of language learning process and enhancing this ability.
