An Overview of the Brain & How The Parts Take Part in Your Life
Even with advanced technology none may unveil all of the human brains' secrets. Maybe they are not secrets at all, but clear truths. Still, modern technology may not help humans know every single detail of themselves. This is because to study a brain truly, it must be alive. But to dissect it, it must be out of the skull. When it is out of the skull, the patient dies. Thus, trying to understand all the brain may be futile. But do not excuse yourself from learning something of your brain. When you understand even a part, you understand your behaviors. You can then use the information to better your life.
Eight bones joined on suture lines make up the skull, and the skull is for the protection of the brain. Therefore, if it becomes cracked, inundated, sickly, or more, you are likely to suffer.The brain is a major part of the nervous system. There are two parts of the nervous system: the central and the peripheral. The central nervous system begins in the brain and the spinal cords. On the other hand, the peripheral nervous system consists of the spinal nerves from the spinal cord and the cranial nerves from the brain. This peripheral nervous system includes the autonomic nervous system, which controls heart rate, breathing, digestion, and secretion of hormones.Also, the brain itself consists of the brain stem, cerebrum, and cerebellum. The cerebrum has the right and left hemispheres, and the cerebellum is below the cerebrum. Whereas the cerebellum is for posture, muscle movements, and balance, the cerebrum is for math, reading, logic, and other intellectual endeavors.
The Left and Right Hemispheres
The left hemisphere controls the right side of the body and the right the left. Thus, when writing with your right hand, you are using your left hemisphere. When passing a football with your left hand, you are using your right hemisphere. The left hemisphere controls most language and math functions. It processes the symbols, performs computations, and retrieves memories. Given that it is mathematical, it is rational, realistic, precise, and a planner. Whereas the right hemisphere concerns itself mostly with visuals, spatial processing, and music. It helps process what you see. Many say it is the emotional, artistic, and a dreamer.Although these characterizations are somewhat accurate, they are not all so. The right hemisphere also participates in determining the context and tone of language. Some websites such as lifehack.org oversimply the workings of the brain. Based on the left-hemisphere-right-hemisphere ideology, they give you tips how to learn better. They also tell you how to understand your personality. But just because the brain has a divide, it does not mean that all its functions depend on the divide.A new study even failed to find evidence that people were dominant either in their left or right hemispheres. Here, the University of Utah researchers scanned the brains of over 1000 people between 7 and 29 while they read. They maintained the study over two years. Overall, there are some differences in the concentration of function. But this is not so much so that one function is fully the left or the right side. Conclusively, you cannot base your whole personality and life on simplifications of complex brain workings.
