1. The Triune Brain Theory, developed by Paul MacLean, is based on evolutionary development and is composed of three interconnected layers of the brain: neocortex, limbic system, and the reptilian complex. According to MacLean, in order for learning to take place, information must be applied in a way that speaks to all three of the brains, as they do not work independently of each other. The information presented to a student by teaching must appeal on a logical and cognitive level to the neocortex, an emotional level to the limbic system, and to an instinctive survival level to the R-Complex. For example, a teacher can appeal to the neocortex by providing positive feedback to help motivate a student to learn. This positive feedback provides as student with a sense of pleasure with the learning process, thereby appealing to the limbic system. Additionally, since positive feedback is used as a motivational tool, the student will be instinctively ready and willing to learn, which is reflective of the R-complex. The Split Brain Theory was coined by Roger W. Sperry, who was awarded the Nobel Prize in 1981. During his study of epilepsy, he discovered that by cutting the corpus callosum in half he could reduce the severity of epileptic seizures in patients (1). Because people are said to prefer one side of thinking over the other, educators need to apply this theory to both sides of the brain in order for learning to be effective. For example, if educators want to appeal to the right-brain thinker then they could implement the use of songs, poetry, or use of props when learning a concept, especially in groups. On the other hand, when appealing to left-brain thinkers, one could implement the use of a crossword puzzle for vocabu... ... middle of paper ... ...a big disparity between the rich and the poor, as only the rich could afford this technology. Another possible positive ramification is that we can develop enhanced senses and cognitive function by the merging of biological (brains) and mechanical (robots) systems in cyborgs (6). Even though this sounds far-fetched and extraordinary, it has some serious drawbacks. For example, we as human beings are able to feel and experience things in life, such as love, through our senses (touch, taste, smell, etc.). If we are stripped of those senses via mechanical systems, then do we destroy this ability? And could these mechanical systems produce super human strength and possibly become destructive? I think so, as the movie “Iron Man” comes to mind. Where do we draw the line between what is a benefit verses what is a risk when it comes to cyborgs? Only time will tell.
