Brain asymmetry refers to the unequal involvement of both hemispheres of the brain in different mental functions. In their general anatomy, the two hemispheres are very similar but there are a number of finer features that distinguish them from each other (Annett, 1985 ). The link between these structural differences and functional differences remains poorly understood. The asymmetry of brain function has been demonstrated both by studying the effects of brain damage on accidental faculties cognitive, but also more recently through the techniques of brain imaging showing asymmetric activations following mental operations, performed which is recorded as evidence of brain activity (Vallortigara & Bisazza, 1999). Despite significant progress on this issue, there are still many points of discussion. The link between these asymmetries and hemispheric dominance is still under scientific investigation, and the mechanisms neuro-developmental factors that lead to these asymmetries are under study. This paper evaluates the impact of brain lateralization on human learning. There are significant ways in which the left hand side of the brain is different from the right hand side. The left temporal cortex neurons have developed the capacity to discriminate and identify sounds and syllables of words emitted by the human voice (Beaton, 2004). While the right temporal cortex neurons are sensitive to musical characteristics of the voice. The hemispheres, right and left, have differentiated to process information in its entirety. Other integrative functions are assigned to each different hemisphere. The left hemisphere is more involved in understanding spoken language but also in logical reasoning and in the motor control of the right side of the body (Capacchione, 2001). While the right hemisphere is more involved in music perception, emotional perception, and visual-spatial control, creativity lies in the motor control of the left side of the body. However, the development of these functions is dependent on many trainings and activities of each person (Morris, Left Brain, Right Brain, Whole Brain?, 2005). Although dedicated to certain functions by programming dependent on genetic information, the brain areas may change depending on their capacity and plasticity of living. The brain is an organ unique to each of us. Left Brain

It is said to be analytic, logical, mathematical, sequential −It works preferably from the detail
It is the seat of language preferred, but not exclusively The study of aphasia (language impairment associated with localized brain damage) showed that a lesion localized does not always match the same pathologies. Thus, about a quarter of a configuration have left hemispheric opposed to the language. Note too that lateralization is not yet established in children, the brain is still malleable until about age 9 to 11 years, some say until adolescence, which would be consistent with the process of myelination (Pinel & Dehaene, 2010). Other exceptions may also be mentioned: the illiterate (in fact, learning to write left to reinforce the dominance for language), the bilingual and multilingual (right cerebral hemisphere of right-handers can play a role in acquiring a second language, especially when learning takes place in adulthood). Finally, there is variability in symptomatology depending on the structure of language speaker’s brains (all languages are not treated the same way) (Capacchione, 2001). Right Brain

It is called analog, empirical and intuitive.
It works rather on the whole, the trial and error, and the deduction. −It is the seat of prime image processing and nonverbal communication −The analytical intelligence
It is exact in nature and is fully expressed in detail, in abstraction, and in indexing. This is the basis of science,...
