V.S. Ramachandran’s Phantoms in the Brain is a well-written book for what he believes to be the causes for some neurological theories and mysteries. He covers many syndromes such as Phantom Limb syndrome, the Capgras Delusion, Cotard’s Syndrome, Hemi-neglect, Blind-sight, Motion blindness, Anosognosia, multi-personality disorder, and the Zombie with in each of us. When he talks about these syndromes he is arguing for the theory of not having a soul because it is not physically tangible and using the neurological theory of consciousness to prove said argument. Though there is a theory of the soul he consistently proves that there is no such thing as a soul that we can physically obtain in our world. So, the question is, do souls exist or are they a figment of imagination and a coping mechanism for humans? Souls do not exist because whether one believes in them or not, they cannot physically be dealt with in the real world as shown through patients with Phantom Limb Syndrome, Capgras Delusion, and Blind-sight syndrome.
Phantom Limb Syndrome is when a patient has lost a limb, such as a body part (organs), an arm or leg, but can still feel the presents of the limb and is “able” to continue functions with the arm because of the presents of the phantom. This syndrome can be caused by losing a limb in a tragic accident or by being born without a limb or limbs. When people are born without the limb or limbs and have this syndrome it can be described as wishful thinking or by having a soul. Wishful thinking is where the person wishes that they have the syndrome but they actually do not even if they are showing the signs of having the syndrome. This sort of thinking can be shown in the case of John McGrath who was an arm amputee that had co...

...e he is not conscious and is thus not responsible for his actions. Even though he is unable to do many of these things he is still able to function in the world and complete tasks. He just will not have any memory of doing said tasks when he gets back to being conscious.
Blind-sight is when the patient is legally blind but can perform tasks of everyday life as if they were able to see perfectly. (not able to see but are able to perform tasks as if they are able to see, zombie?)

When we go about our daily lives there are many things that go undetected. One such undetected event goes on inside our own head. Thinking without thinking, an idea brought forth in Malcolm Gladwell’s Blink, where your brain is processing information that you aren't even aware of yet. Some of the best outcomes are produced from this “idea”. Another huge topic in this novel is the idea of “thin slicing”. Where your brain can come to a conclusion within seconds of analyzing the situation. Thin slicing is proven in this book to be more resourceful than putting any length of thought into a situation. But in order for Gladwell to drive home his ideas, he is going to need the help of some psychologists tests to prove that he is right.
In J.J.C. Smart’s essay, Sensations and Brain Processes, he disagrees with dualism as he believes that states of consciousness and brain processes are similar. He presents a case where he reports that he sees a round and yellowish-orange after-image. He describes various perspectives about what he is actually reporting. He claims that he could not be reporting anything, and that this after-image is only the result of him having a temptation to say that he sees it. Another example involves an individual reporting pain, and, like the after-image example, he or she could not be reporting anything as well. In regards to both the reporting of the after-image and pain, Smart disagrees with the claim that these reports are “irreducibly psychical,” (Rosen 372) which means they cannot be reduced to mental properties.
Neuroscientists claim that due to unconscious brain activity, we are “biochemical puppets” (Nahmias). Through experiments conducted by neuroscientists like Itzhak Fried, neural activity is shown to occur before a conscious decision is made. Fried concluded that this was a predetermined occurrence
Overall, there is an immense amount of research dedicated to understanding the psychobiological causes of phantom pain. A prevalent commonality between the literatures reviewed, suggested that symptoms of phantom pain are a neuro-psychobiological experience rather than a psychological disorder. This was evident by peripheral and central factors that associate the cause of phantom pain with the disruption of sensory nerve impulses due to the damage of sensory nerve fibers after amputation. As well as studies that demonstrated a positive correlation between progressive neuroplastic changes in the cortical reorganisation of the topographical structure in somatosensory cortex and worsening phantom limb pain, inferring that cortical reorganisation mediates the extent of pain experienced.
As far as I could remember I was never really any good at school. I couldn’t concentrate on things for no more than 5 minutes at a time I would either get discouraged or find it too easy and just give up. An author by the name of Carol Dweck wrote an article called “Brainology” in it Dweck describes that there are two types of mindsets fixed and growth. Those who are afraid to fail so they never try anything new are ones with a fixed mindset and the growth mindset are those who are not afraid to fail and find a new challenge an opportunity to learn something new. I guess you can say that I had a bit of a fixed mindset growing up I was always too scared to look stupid that I didn’t want to fail because I didn’t want to disappoint my siblings
David Eagleman, in his book Incognito: The Secret lives of the Brain, explores the relationship between the conscious and unconscious mind. Referencing many real-life stories and scientific experiments, Eagleman argues that we governed more by our unconscious. The book explores one main question: “If the conscious mind - the part you consider to be you - is just the tip of the iceberg, what is the rest doing?". We are not aware of what the rest of brain, the unconscious, is doing; rather, “the brain runs its show incognito” (Eagleman 7). In my book report, I have interwoven my synopsis and my reflection/connections to what we have learned in class so the essay flows more chronologically. Additionally, I chose the examples and case studies that I believed best reflected the central argument of the book. For quotes, I only included sentences that reflected a main idea and terms/phrases that
Richard Taylor explained why the body and the mind are one, and why they are not two separate substances. In the article “The Mind as a Function of the Body”, Taylor divides his article in a number of sections and explains clearly why dualism, or the theory that the mind and the body are separate is not conceivable. In one of these sections it is explained in detail the origin of why some philosophers and people believe in dualist metaphysics. As stated by Taylor “when we form an idea of a body or a physical object, what is most likely to come to mind is not some person or animal but something much simpler, such as a stone or a marble”(133). The human has the tendency to believe a physical object as simple, and not containing anything complex. A problem with believing this is that unlike a stone or a marble a human (or an animal) has a brain and the body is composed of living cells (excluding dead skin cells, hair, and nails which are dead cells). The f...
In cognitive terms, this young man is an example of a misperception in kinesthesia. The inability to comprehend the loss of a limb is both terrifying and unnerving. In the story at hand, the patient believes that what they see is unlike anything he has seen before. The patient believed the leg he found in his bed was not his own. In terror and amazement, he was stupefied when Dr. Sacks informed him the leg he had been seeing was his own.
You wake up in a hospital bed, scared, confused, and attached to a network of tubes and beeping equipment. After doctors assault you with a barrage of questions and tests, your family emerges from the sea of unfamiliar faces surrounding you and explains what has happened; you have had a stroke in the right half of your brain, and you are at least temporarily paralyzed on your left side. You wiggle your left toes to test yourself; everything seems normal. You lift your left arm to show your family that you are obviously not paralyzed. However, this demonstration does not elicit the happy response you expect; it only causes your children to exchange worried glances with the doctors. No matter how many times you attempt to demonstrate movement in the left half of your body, the roomful of people insists that you are paralyzed. And you are, you just do not know it. How is this possible? You are suffering from anosognosia, a condition in which an ill patient is unaware of her own illness or the deficits resulting from her illness (1).

Historically, cognitive psychology was unified by an approach based on an resemblance between the mind and a computer, (Eysenck and Keane, 2010). Cognitive neuroscientists argue convincingly that we need to study the brain while people engage in cognitive tasks. Clearly, the internal processes involved in human cognition occur in the brain, and several sophisticated ways of studying the brain in action, including various imaging techniques, now exist, (Sternberg and Wagner, 1999, page 34).Neuroscience studies how the activity of the brain is correlated with cognitive operations, (Eysenck and Keane, 2010). On the other hand, cognitive neuropsychologists believe that we can draw general conclusions about the way in which the intact mind and brain work from mainly studying the behaviour of neurological patients rather than their physiology, (McCarthy and Warrington, 1990).

Blind-sight is when the patient is legally blind but can perform tasks of everyday life as if they were able to see perfectly. Ramachandran believed this syndrome came from damage to the specific part of the visual cortex that corresponded with vision but also function. Therefore:
