Recommended: Split brain research

The concept about the split-brain cases is two hemisphere separate apart, where means the left side focus on the left side, the right side focus on the right side (Parfit 378). He thinks that the concept of the split-brain and the normal brain are both true. Parfit denies that there are no person involved, also the ego theory doesn’t exist. He believes that once the brain has split apart, it has two separate streams of consciousness (Parfit 378). So, he claims that instead of asking “what happened to the original self?,” he says there is no ‘self’ (Parfit 379). Even though there are different events happened at the same time, that is not equal to different egos. “There are not here two different possibilities, one of which be true. These are

    In “Can You Build a Better Brain”, the author, Sharon Begley discusses how the cognition processes better. He starts by presenting some experiments that prove nutrition did not support the brain smarter. According to the article, he believes that the “cognitive capacity” can be amended by concentration in people’s behavior. He further believes that people’s intelligence do not depend on own skills; however, as long as people peceive new things, their synapses and brain systems will

  • The Brain on Trial by David Eagleman

    574 Words  | 2 Pages

    In “The Brain on trial”, David Eagleman (2011) recounts the horrifying events which occurred on August 1, 1966. Charles Whitman entered the University of Texas with a rifle and secured himself in the bell tower. He then proceeded to shoot and kill 13 people and injure 32 more. Whitman was also shot and killed; however, during his autopsy it was discovered that a tumor was pressing against his amygdala. According to Eagleman, “The amygdala is involved in emotional regulation, especially of fear and aggression” (2011). Therefore, Whitman was possibly experiencing a fundamental change in his emotions and personality due to the tumor. Though Whitman did not survive, his case still poses questions as to whether or not he should be held accountable for his actions; moreover, should Whitman have received the maximum punishment for the murder he committed? Charles Whitman may not have had control over the feelings of “rage and irrational thoughts” (2011) he was experiencing; however, the precision of the attack indicates he was well aware of the actions he was committing.

  • Left-Brain vs. Right-Brain: Debunked but not Dead

    720 Words  | 2 Pages

    Over the past few decades popular culture has conditioned us to think that the way we learn depends on our personality and cognitive style. We have been taught that we are all either right-brained or left-brained thinkers, a theory called brain lateralization. The thought comes from the fact that certain functions come from one side of the brain or the other. Thus, if you are a logical thinker then you are left-brained, and if you are the creative type then you are right-brained. Unfortunately, none of this is true. Brain lateralization, at least in this function, has never been proven, or even supported, by science.

  • How Flexible is the Brain's Circuitry?

    1696 Words  | 4 Pages

    The brain is a complicated organ, containing an estimated 100 billion neurons and around 1,000 to 10,000 synapses for each of those neurons (1). This organ has the great responsibility of not only controlling and regulating the functions of the body but also sensing and perceiving the world around it. In humans, it is what we believe makes us the highly adaptive and intelligent organisms that we are, as well as give us our individuality. But with so many parts and connections to it, what happens when the brain's delicate circuitry is disrupted? We've all heard of brain damage, and its horrible results, whether is a news report on TV or science books. It seems that with trauma, disruption of blood supply, and disease; neurons and their connections could be destroyed and the organism's behavior exceedingly affected. Yet I've read about how people have overcome tremendous damage to their brains and gone on to function with very minimal handicaps.

  • Left-Brain Vs Right Brain Theory

    688 Words  | 2 Pages

    Can one be considered left-brained or right-brained? Recent findings prove that no, one cannot. Before doing research on this topic, a person may think they are one or the other however it seems that that may not be accurate any longer. Although the left-brain, right-brain theory is a popular theory in the classroom, recent research just may have proved the theory wrong.

  • Sensations And The Brain Essay

    1919 Words  | 4 Pages

    This leaves a particularly large hole in identity theory. From neural dependence and the causal problem, it is almost impractical to endorse any type of dualism. But multiple realizability makes identity theory suspect as well. Also emotional additives, and the fact that epiphenomenalism is self undermining but not impossible, lead to slight suspicion of physicalism in general. Basically, this paper set out to endorse and defend identity theory but has concluded nothing definitively.

  • Personal Identity by Derek Parfit

    Parfit uses a famous case of division (or fission), as imagined by Wiggins (1967), to illustrate his claim that identity is not what matters in survival. When A’s brain is split into two parts, each housed within two separate, brainless bodies (B and C) it seems that we have three options. We either believe that:

  • Essay On The Meditations By Descartes

    1169 Words  | 3 Pages

    ... Theory is instrumental in explaining how the mind can be considered an entity that is separate from the body. We can come to this conclusion by first understanding that we are real, and we cannot logically doubt our own presence, because the act of doubting is thinking, which makes you a thinker. Next, we realize that the mind, and all of its experiences and thoughts, will remain the same no matter what changes or destruction that’s endured by the body. Then we can grasp that we are our minds and not our physical bodies. We can use a number of examples to illustrate that these concepts, including the movie The Matrix. Finally, we can disapprove John Locke’s objections to the Dualist Theory by identifying that the mind is capable of conscious and unconscious thought; therefore, it cannot be divisible like the body. Hence the mind is a separate entity from the body.

  • The Distinction Between the Mind and Body

    476 Words  | 1 Pages

    Some would choose to declare that every human being is both a body and a mind. Both being gelled together until death, than having the mind go on to exist and the body being lifeless. A person lives throughout two collateral histories, one having to do with what happens to the body and in it, and the other being what happens in and to the mind. What happens to the body is public and what happens to the mind is private. The events which reply to the body consist of the physical world, and the events of the mind consist of the mental world.

  • Responses to the Doctrine of Mind-Brain Identity

    2365 Words  | 5 Pages

    The theory or doctrine of mind-brain identity, as its name implies, denies the claim of dualists that mind and brain (or consciousness and matter) are distinct substances. The tradition of dualism, whose clear-cut foundations laid by Rene Descartes (1596-1650) were built upon during succeeding centuries, sharply distinguishes between the stuff of consciousness and the stuff of matter. An outline of the position of the dualist will give a context for the identity theory.

  • Divisibility Argument

    802 Words  | 2 Pages

    This paper will discuss the dualism’s Divisibility Argument. This argument relies on Leibniz’s Law and uses a different property to prove the distinctness of brain states of mental states. Mary, who is a materialist, presents several objections to that argument. Her main objection corresponds to the first/third-person approach. She believes that Dave presents that argument only from the first-person approach, which is introspection, and totally disregards the third-person approach, which is observation of another mind. Mary’s objections will follow by the Dave’s response on them from the dualist’s point of view.

The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.

  • Compare And Contrast Mind And Body Dualism

    2076 Words  | 5 Pages

    In a world of science, religion, ignorance and opinion common perception on whether or not the mind is separate from the brain has switched more times than one can track. A dualistic view on the body/mind relationship continues to be scrutinized day in and day out. As I will explain throughout the argument dualism is facing increasingly more constraints as time goes on. An evaluation of the mind/body argument from a Humean perspective proves dualism to be flawed in key aspects, where in contrast a materialistic approach is not affected.

    The brain is an astonishing product of evolution. This can be seen by our numerous technological developments and society structure. The brain has always been the most important organ for species that had developed past the cellular stage and has always performed the same functions that it does now but has developed constantly to where it is now through growth and a reorganization of its’ primary functions and gained the ability to learn has been something that the human brain does better than other brains. Our brains have not always been like this and many social and biological factors have led us to where they are now.
