But he forgot throw the sand before hitting the bar, so when he did it there was an explosion that make the bar went to his head, the bar had a measure of 3 cm of diameter, and 1 meter of large.

Lateralization is the idea that the two halves of the brain's cerebral cortex,helps us to understand our behavior, our personality, our creativity, and our ability to use the proper mode of thinking when performing particular tasks. The real concept of Brain Lateralization is a longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. The sides resemble each other and each hemisphere's structure is generally mirrored by the other side. The brain lateralization research showed that many of these negative avoidance and emotional tendencies were mediated by the right, non-dominant, unconscious hemisphere. The term brain lateralization refers to the fact that the two halves of the human brain are not exactly alike. Each hemisphere has funcitonal specializations: some function whose neural mechanisms are localized primarily in one half of the brain.
