Handling the Brain Essay

The human brain is a wondrous invention that has many scientists and researchers very busy to this very day. There are numerous qualities about the brain humans know about, yet there are still a great number of mysteries to the brain and how it functions left to be discovered and shared. Some facts scientists do know about the brain is that it is divided into to primary sections, called hemispheres. Each person has a left and right hemisphere of the brain. Each hemisphere is in charge of specific abilities, tasks, and functions. This paper will review what each hemisphere is responsible for and describe ways that each hemisphere is predisposed to learn.

In the excerpt “Right Brain Rising”, Daniel Pink tells his experience in depth detail of an intriguing brain scan beneficial both to his curious mind, and the world of science. He then goes on to inform readers of the two distinct halves resting in our skulls; following up with the past inferiority associated with the human right brain, thought to be due to years of evolution. After acknowledging the disproved theory, Pink delves into information pertaining to psychology’s six

Using a real human brain, Dr. Taylor explained the separation of the brain’s right and left hemispheres. The two cerebral cortices are completely separate from one another, but maintain communication via the corpus callosum. She described the right hemisphere as a parallel processor, thinking in images and learning from body movement. The right hemisphere is responsible for gathering sensory input, in the form of energy, from the environment around us. The left hemisphere, according to Dr. Taylor, is a serial processor, interpreting the sensory information gathered by the right hemisphere. The sensory information is analyzed and categorized by the linear and methodical thinking of the left hemisphere. Dr. Taylor believes the left hemisphere is responsible for interpretation of the past and future, as well as, an individual’s self-awareness. The

The book starts with the Chapter Right Brain Rising describing hemisphere of left brain and right brain. According to Pink the left brain hemisphere is consistent of logistic, literal and analytic personal whereas right brain is for holistic reasoning, body language, patterns recognitions and emotions. He carefully pointed out that the term L-Brain

In class on 9/18, we discussed the structures of the brain and how each part works. The brain has so many parts that it is almost impossible to remember all the parts and their functions. The brain is very complex, but the most interesting thing that was talked about was the two different hemispheres. We discussed how the right hemisphere controls the left side of the body and vise versa I found it very interesting that the left side of the brain controls more of our logic and grammar, and the right side of the brain controls more emotional expressions. When Dr. Yarnell discussed her story of her friend and her friend’s husband getting in a fight I think the way she told her to help resolve it was very interesting. Her response was to move into her left side

Let’s start out with Jacquelyn McBain, an animal and human behavior specialist who commented on a question displayed on a website called Quora. McBain wrote that right handed people tend to turn towards the right while left

Pink’s argument that we are moving out of a left-brain dominance and in to a new era where right brain qualities will be prized is well illustrated in part one the book. According to Pink “the two hemispheres of our brain don’t operate as on-off switches…both halves play a role in nearly everything we do” (2011). Pink suggests that both hemisphere of the brain are equally important. In fact, “a healthy,

Mead & Hampson (1996) developed a study involving the divided visual field paradigm and a phonological rhyme/non-rhyme task to test the speed and accurateness of either side of the brain. This study was used to investigate functional asymmetry between the left and right hemispheres in phonological processing. The research was taken out equally on 15 male and 15 females London Metropolitan University students ranging from ages 18 – 35 years old. They were all specifically chosen to be right–handed and had English as their first language thus providing a fair experiment to see whether our left hemisphere (left side of the brain) or the right hemisphere is faster and more accurate. In conclusion using the mean and standard

For many decades people have been considered to be either right or left side dominant in regards to brain function which came with defined roles such as “creative” or “analytical”. This thinking tends to be over-simplified as most people use their entire brains daily (Jensen, 2010). On the other hand people do use different parts of their brain for different tasks according to how they perceive those tasks.

In 1967, M.S. Gazzaniga studied the split brain in man. Gazzaniga wanted to study how the two halves of the brain functioned independently. Since it a little unethical to snip the peoples corpus callosums just for fun, it wasn‘t until doctors discovered that cutting the corpus callosum could actually cure severe epileptic seizures that it was possible for Gazzaniga and Sperry to study them. They found that the test subjects intelligence, personality, and emotions had not changed. We use each half of our brains for specific skills. Three different tests were designed to check mental capabilities. It was found that the left-brain is better at speaking, writing, reading, and math, and the right brain is better at recognizing

In the Conceptual Age, it will not longer suffice to rely heavily on the logic of the left brain. Computers, cheaper sources and labor will continue to lead to outsourcing of this work; instead, creativity and innovation will give rise to future development. To prosper in the Conceptual Age, people will need to weave together the logic of the left brain (L-directed thinking) and the creativity of the right brain (R-directed thinking).

Left-right brain dominance is about the fact that the distinct hemispheres influence thinking. The left hemisphere is associated with logical, analytical thinking and a linear approach to problem solving. The right hemisphere is associated with creative, intuitive and value-based thought process. It is important to note that everyone uses its both hemispheres, but to varying degrees. Four quadrants of the brain, related to different thinking style, have been identified:

Handedness is a complex phenotype of humans in which individuals have a preference or advantage for use of a hand. Handedness is a not a discrete trait, but continuous. Right handedness is accepted as normal over left handedness. There are four types of handedness (left-handedness, right-handedness, mixed-handedness, where one hand is favoured for some tasks and the other hand for different tasks, and, ambidexterity where each hand is equally strong) however, handedness is a continuum so individuals can fall within a range of different degrees of handedness. Left handedness is less common than right handedness, with only approximately 10% of people being left handed (Hardyck & Petrinovich 1977). Left handedness can be further divided in to natural left handedness, where a person whose handedness is a result of genetic and cultural factors, and pathological left handedness caused by early damage to the left hemisphere of the brain.

The evolutionary trend of cephalization brings upon a bilateral symmetry of organized development which in embryology leads to a development of an anterior brain in chordates. This trend continues with lateral symmetry, lateralization, to where there are left and right handed lateralizations. Specialization can occur when the left and right hand hemisphere can be altered specifically, allowing for separate changes in lateralization in either direction, which can be beneficial with things such as cognition and performing two different tasks at the same

The study determines that, it is not the brain that decides if people are right handed or left-handed, however the spinal cord does that job. The researchers have showed that the gene activity in the spinal cord is already in the uterus.
