Phantom Limb Pain: A Case Study
Because people who have phantom limb pain complain of a constant pain many health practitioners have attempted surgery based upon the premise that it is a nerve issue; however, surgery to fix the pain is unsuccessful. Ramachandran came up with the concept that the somatosensory homunculus on the right side of the brain has the representation of the face next to the hand on the cortex. Because the hand is no longer present, there is no stimulus coming from the hand to the somatosensory cortex. The cortex wants stimulation from the hand therefore the face encompasses the hand section of the somatosensory cortex and begins to activate the hand when the face has a stimulus. This apparent reorganization of the individual’s somatosensory cortex
Dr Norman Doidge The Brain That Changes Itself Analysis
1371 Words | 6 PagesFor example, when researchers were working with the mental mirror box, a box that tricks the brain of a patient with a nonexistent limb that the limb is actually there by reflecting the healthy limb, they found that the individual feels as if the limb is present and healthy. Researchers also found that if an individual scratches a particular spot on his or her face, that fulfills the itching sensation that was previously felt on the nonexistent arm. This is because when one area of the brain is not being used, such as the arm map when the arm is amputated, another part of the brain map takes over, such as the face. This is an extremely interesting finding which explains why blind or deaf individuals experience such profound functioning in their other

Corpus Callosum: The corpus callosum connects both hemispheres of the brain and allows them to relay messages between one another.

Frontal Lobe: As the largest lobe in our brain, this lobe play a significant role in personality and impulse control.

Write An Essay On Igor Spetic
855 Words | 4 PagesHaptic systems recreate the sense of touch by applying forces, vibrations, or motions to the user, which enables them to recognize the objects through the process of touch. In the process of developing the Haptic system (a joint development by Louis Stokes Cleveland Veterans Affairs Medical Center and Functional Neural Interface Lab at Case Western Reserve University), Spetic grabs the cherry between his prosthetic thumb and forefinger so that he can pull off the stem. Instead, the fruit bursts between his fingers. Next, the Haptic system is used to stimulate different nerve fibers which produces realistic sensations that Spetic perceives as coming from his missing hand: when one spot is on his hand is stimulated, he feels a touch on his right palm; when another spot on his hand is stimulated, he feels a touch on his thumb; and so on until he can feel touch on most of his hand. Tests are then conducted to find out whether such sensations would give Spetic better control over his prosthetic hand.
Abigail Zuger Sometimes Pain
108 Words | 1 PagesIn the article, “Sometimes Pain Is a Puzzle That Can’t Be Solved”, Abigail Zuger, the author, describes her own experiences with pain along with some examples and generalizations about the feeling. She claims that she is “ruled by (her) elbow” and “it is (her) constant companion, whimpering, and tugging at (her) sleeve.” She goes on to say that many people have the same problems, especially when drugs, “like naproxen and ibuprofen” are unhelpful and “might as well be cornflakes.” Finally, she explains how far we have advanced in the medical field, but “ none of (the) knowledge has translated into new treatments,” to help people such as herself.
Phantom Limb Pain Summary
199 Words | 1 PagesDue to the presence of the mirror the individual visually perceives that both hands are there and functioning. To release the clenching pain the person clenches both “hands” and releases. Upon the release of the hands the individual feels the clenching pain begin to subside in their phantom limb; therefore, the individual continues to clench and release whenever the pain becomes unbearable again. The second case presented to Ramachandran does not fit with the theory provided. The second case is showing that the brain needs to experience a type of placebo effect with visual stimuli to ease the clenching phantom limb pain.

Matthew Nagle
828 Words | 4 PagesA company named Braingate has developed a combination of hardware and software to directly sense the neuronal signals in the brain which controls limb movement. This device, with the size of a baby aspirin, when implanted in the brain records the neuronal signals and sends those to a computer, which then converts the signal to digital instruction and performs actions like moving a cursor. In 2006 the first clinical trial was performed on a 25 year old quadriplegic paralyzed person named Matthew Nagle. The trial became a grand success when after some practice Nagle could move and click a computer cursor and even make a robotic arm pick up small things.

Advantages And Disadvantages Of PET Scan
1234 Words | 5 PagesThroughout history, left-handed individuals have always been perceived as being less intelligent than right-handers, for example, they were still forced to use or write with their right hand. The use of the left hand signifies the lateralized output from the opposite hemisphere. Localization is defined as specific locations in the brain which corresponds to behavior, emotions, and thoughts (Linquist, Wager, Kober, Moreau & Barret, 2015). In the 19th century, Paul Broca tested the localization theory of functions in the brain. During his investigations of this theory, he gathered sufficient evidence, which included problems, and details of medical issues that patients faced.
