One Brain or Two free essay sample

Many agreed to participate in the experiments. The experiments that they held focused on finding out what kind of limitations would each brain have if they operated independently, how the 5 senses would be affected as well as finding their unique abilities. The two hemispheres were analyzed with three different tests. One of the tests studied their visual abilities and interpretations. The test consisted on placing an image at a specific place while having their eyes fixed at a determined point.So that would make the patient capture the visual information in only one of the visual fields (area) of the right or left hemisphere. Interesting findings came out of this test. The patients claimed verbally to not have seen anything on the right field. However, when they were asked to point at the image seen, they pointed at the image on the right field where they had claimed to not have seen anything.

Another of Gazzaniga and Sperry tests focused on tactile stimulation. This test was really simple. It consisted on being able to touch different items without seeing or hearing it. The results of this experiment give to the previous Gazzaniga and Sperry logical conclusion more credibility. At the time the patients used their right hands (connected to the left hemisphere), they could not name or describe verbally anything related to the objects.However, it was not the same story with the left hands of the patients (connected to the right hemisphere). They could match and point at the objects without problem; proving again the lack of speech ability that the right hemisphere has. The other test held was an auditory test. The test was done in two different ways. One way was finding the objects in a bag that were mentioned verbally and the other was identifying the item reached by touch. This test’s results were also supporting the previous researchers’ logical conclusion about the left hemisphere ability of speech.It confirmed the right hemisphere’s ability of comprehending language and its ability of expressing it in a nonverbal way. During the test, evidently, the right hemisphere had no trouble identifying the unknown objects by touch as the left hemisphere did. Moreover, some three- dimensional drawings of the slit-brain patients, who were all right handed, developed much better drawings using their left hands compared with their right hands. Those three types of tests were combined to make new tests. But the results are all similar to the ones mentioned before. These amazing findings get us to the conclusion that we possess two different brains with different abilities and behaviors. Gazzaniga emphasizes the possibility of doubling the brain’s performance by separating both halves. In other words, to put each brain half to think on their own. I find this hypothesis of perhaps being able to manage 2 tasks or having 2 extreme different thoughts at the same time very interesting. Knowing that something that sounds like fiction could actually be a possible truth one day provokes me countless thoughts about our so uncertain future.

Free Essays on Yoga And Its Benefits

YOGA AND ITS BENEFITS Many health and lifestyle benefits are associated with the practice of Yoga. However, it is impossible to understand the attainment of these benefits without explaining the classical form of Yoga, Ashtanga Yoga, as a way of life, the philosophy it is based on, and the eight methods that makes it up. Yoga is a way of life whose creation and systemization is credited to Maharishi Patanjali. According to Patanjali, the basic idea of yoga is to unite the atma or individual soul with the paramatma or the Universal Soul. According to Yoga philosophy, by cleansing one's mind and controlling one's thought processes one can return to that primeval state, when the individual self was nothing but a part of the Divine Self. This is the sense encapsulated in the term samadhi. The aim of the yogi is to be able to perceive the world in its true light and to accept that truth in its entirety. The term 'yoga' stands for 'union'. A yogi's ultimate aim is to be able to attain this 'union' with the Eternal Self with the help of certain mental and physical exercises. Different schools of thought have been derived from Ashtanga Yoga, but they all adhere to different applications of the Ashtanga discipline, and are all ultimately aimed at liberation of the soul and an understanding of the Divine Un ity. For the purposes of this paper, the understanding of the benefits that can be derived from Yoga, only and in-depth discussion of Ashtanga Yoga is necessary. The Patanjala Yoga philosophy is also known as Ashtanga Yoga and is the practical manifestation of the Sankhya and Vedantic philosophies. It is an attempt to understand the nature of the mind, including â€Å"Its different states of being, impediments to growth, afflictions and the methods of harnessing it for the achievement of absolute self realization†.
