About Human Brain
The brain of humans is made up of two halves, a left and a right brain. There’s a big fold in the human brain, which divides the brain into two different parts. Well, almost different.? These parts are linked with each other by a network of nerves, at the base of each brain. The only link present between the two parts is called the corpus collosum, which is similar to an Ethernet cable or network connection between two fast computer processors, each running different program from the same input. The left side of our body is linked to the right side of our brain and the right side of our body is linked to the left side of the brain. For whatever reason, nature did this connection; it even applies to our eyes, which process the majority of our sensory data on opposite sides of the brain.
How is your brain positioned?
- Prefrontal Lobe – This lobe plays a key role in problem solving, naturalness, impulse control, working memory and socialization. Prefrontal lobes help in controlling, coordinating, planning, performing behavior creating personality expression and moderating social behavior. Those people who have a damaged prefrontal lobe experience behavior disorders, difficulty in learning new things, no goal-direction and emotional ability with “Flat effect” (unemotional).
- Frontal Lobe – This lobe is the largest lobe of the brain and is located behind the forehead. Frontal lobe is much prone to the injury as they are in the front of the skull and around rough edges. This lobe helps in handling of words and grammar and synthesis and creative thinking and visualization, organizing, analysis, concept and idea formation, memory, decision making, selective attention, reasoning and judgement and planning.
- The Parietal Lobe – This lobe incorporates sensory information from various parts of the body and is located behind the frontal lobes. Parietal lobe helps to keep us from bumping into each other and controls our activities. If any kind of damage happens to this lobe, it causes numbness and impairs sensation on the opposite side of the body. And if the back part gets damaged, it can cause right-left disorientation and problems with calculations and drawings. Damage to the right parietal lobe can cause aphasia – lack of ability to perform simple tasks like brushing hair or dressing.
- Temporal Lobe – This lobe helps in response of hearing input. Right temporal lobe helps in music appreciation, while the left temporal lobe helps in understanding speech. Any damage can result in impaired memory for verbal materials and also for non-verbal material such as music and drawings.
- The Occipital Lobe – This lobe helps us in visual interpretation and visual spatial processing. Any kind of damage to this lobe can lead to discrimination of movement and color. And it can also cause word blindness with writing impairments (alexia & agraphia).
