Roger Sperry's Split-Brain Research

One Brain or Two?, Michael Gazzaniga and Roger W. Sperry explore the independent abilities of the two hemispheres in the brain, the left and right, by studying split-brain patients and their responses to certain tests. The tests are designed to examine the mental and perceptual capacities of the split-brain patients. With careful placement of objects or pictures, the first test measures the visual abilities of the patients. The second test measures the tactile cognition abilities of the patients by allowing them to feel an object behind a screen, then asking them to name the object. The third and more challenging test combines the visual test and tactile test to measure the auditory abilities of the patients. Each of these tests shows the different ways that the brain works in split-brain and normal brain humans alike.

The main purpose of this paper is to discuss what the psychological approach, the split brain case, and the multiple occupancy reply is and how they relate to Egan’s Learning To Be Me story. This essay will be first discussing what the psychological approach is and what the objection to it. It will also discuss what the split brain case is, what the multiple occupancy reply is, as well as how all of this ties into Egan’s text.

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.

The progress of neuroscience has been significant in the past 500 years. and with the advance of technology, there is yet a multitude of chapters left to write in the history books of neuroscience. The book The Tale of the Dueling Neurosurgeons: written by Sam Kean was an engrossing and captivating read. It gives the reader a better appreciation for the growing pains of neuroscience and provides an educational, albeit entertaining overview of the anatomy and physiology of the brain and nervous system. From the early life and discoveries of Santiago Ramón y Cajal and his fascination with Golgi’s method la razione nera, which allowed Cajal to deduct after observing

The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1a. The brain stem is found in the deepest part of the brain. The brainstem controls the automatic survival functions of the body, such as breathing. There are no differences between the function of the normal brainstem and the brain of a split brain patient. The brainstem will still supply the automatic survival functions of the body. 1b. The hippocampus is found in the limbic system along with the amygdala, the hypothalamus. The hippocampus is in charge of allowing the body to process information into memories. Without the hippocampus, there is no way for new memories to be created. There is no anatomical difference between the hippocampus in the normal brain and a split brain. 1c. The corpus callosum is found in the center of the brain. The role it plays as a part of the brain is it connects both the left and right hemispheres of the brain, allowing them to work and interact together as a whole system. The difference between the anatomy of the corpus callosum in a split brain patient versus someone without a

When it comes to the topic of having a growth mindset, most of us will readily agree that students who are praised are motivated to learn. Where this agreement usually ends, however, is on the question of how they are praised. Whereas some are convinced that praising students for their intelligence will motivate them to learn, others maintain that encouraging them for their efforts has a better impact on their motivation.

This video is about The Behaving Brain; it explains how the brain and amnesia work. According to the video, neurons duties are to receive information from other cells, process this information, and transmitting it to the rest of the body. This is done by traveling through dendrites, to the soma, to the axon, to the terminal buttons. Constant nerve flow helps regulate our metabolism, temperature, and respiration. It also enables learning and the ability to comprehend. The brain is connected to the brain stem, which is connected to the cerebellum, which is connected to the limbic system. The limbic system is made up of the amygdala, hippocampus, hypothalamus, and thalamus. The cerebrum is the largest part of the brain, where things are

According to Hetherington and Parke (2002), studies of brain imaging identified that in female bilateralism there were greater amounts of blood flow. The male brain reflects greater lateralization attributing to a higher success rate in spatial tasks and mathematics.

Fine dissects the greater male lateralization (GML) hypothesis that males “are more strongly left hemisphere dominant for language processing and right hemisphere dominant for visuospatial processing” (Fine 280). Females, on the other hand, are thought to engage in both hemispheres

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

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.

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:

directly due to either being left brain or right brain. What is left brain or right brain you ask?

Different statistics study shows that certain percentage of population belong to particular category is likely to be left or right handed. The motor homunculus as shown in the picture represent the division of motor cortex that contribute to different structures of the body. Hand movement involve fine control over the motor area. The differentiation occur in the region of brain more particularly in the motor cortex in the cerebrum. For right handedness people the left hemisphere of the brain dominates and vice versa.. Researchers from University of Oxford and its collaborated universities found the link between the handedness and gene that is involved in this process which is mainly PCSK6 gene[1]. A study conducted with approximately 54,000 individuals revealed that 24% handedness is contributed by genetic factor. [2] These gene can be influenced by cultural and social pressure that can result in right handedness child born to left handed parents. Broca 's area that controls the speech and language is
