What is the left brain?
Cerebrum is the largest part of the brain and is divided from front to two sections. The left brain is the left side of the brain and is also called the left hemisphere. The left and right brain hemispheres have little differences in their functions. This is called functional asymmetry. The left brain is primarily responsible for speech, mathematics and logic and is related to the functions of the right side of the body.
The left brain differs anatomically from the right brain. The structural differences between the two hemispheres are called anatomical asymmetry. Part of the time lobe is larger on the left side than the same area on the right side. This physical difference exists at birth. The Sylvian crack, which is a cleft or groove in the brain, also has a more gradual shape on the left than the right than right.
In 1861, the French Neurosnial Paul Broca studied the brain of deceased patients who had difficulty talking during their lives and found large lesions in their brainsleft frontal hemispheres. His research resulted in the belief that the left hemisphere is important for speech and language. Identified the area in the left brain that acts as a speech center; This is now called Broca's Area. German neurologist Carl Wernicke discovered part of the left brain in the left temporary lobe, which is important for tongue. If this area is damaged, one could speak, but words would not make sense.
In the 1960s, neurosurgeon Roger Sperry and Michael Gazzaniga studied people with epilepsy, brain disorder that causes a person to have seizures. These studies called "Experiments with a split brain" have shown that the left brain is important for speech, mathematical and analytical tasks and the true brain is important for perception of space, music and art. Roger Perry received TV in 1981 for his studies "Split Brain" in 1981 in 1981.
left and right cerebrums are connected by corpus callosum, which is made up of nerve fibers that run across between the two hemisféRami, and Corpus Callosum helps both hemispheres to communicate with each other. The left brain controls the muscles on the right side of the body. It is a dominant hemisphere for motor control over people. The right brain is important for controlling the engine of left -wing people. If one side of the brain is damaged, it will affect the opposite side of the body.
