Right Brain vs. Left Brain and the Impact of Learning
What is the brain? The brain is the hub of the nervous system in all vertebrate and most invertebrate animals, there are only a few early invertebrate that don’t have a brain such as starfish and jelly fish. The brain is usually located close to the main sensory organs such as smelling, hearing, and vision. The brain of a primate is usually the most complex part of the body. The cerebral cortex of a human is estimated to contain 15-33 billion neurons. The neurons communicate with each other by long photoplasmic fibers called axons, which carries direct signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells (1). The purpose of the brain is to give sensible control over the action of an animal and or human. A center brain allows groups of muscles to be co-activated in complex patterns, it also allows stimuli impinging on one part of the body to evoke response in other of the body, it can also prevent different parts of the body from acting at cross purpose to each other(2).
A longitudinal fissure divides the human brain into two cerebral hemisphere connected by the corpus callosum. Both hemisphere mirrors each other and both cortical hemisphere are managed differently. While the functions are lateralized there are only tendencies. The trend across many individuals may significantly different as to how any specific functions are implemented. The area of exploration of this casual or effectual difference of a particular brain function includes its gross anatomy, dendritic structure and neurotransmitter distribution. The chemical and structure variance of a particular brain function between two hemispheres of one brain o or between the same hemispheres of two different brains is still being studied.
Brain lateralization is evident in the phenomena of right and left handedness and of right and left ear preference but a person preferred hand is not clear...
