Hemineglect Studies

Dr. Jill Bolte Taylor describes her experience of a stroke in her left hemisphere on December 10, 1996 causing her to lost the ability to move or talk, as well as her self awareness. Throughout her presentation, she mentions the basic functions of the two hemispheres of our brain: right and left hemisphere. Taylor argues both sides of the brain functions differently and process various of information. Taylor defines the right hemisphere of the human brain is about the “present moment” or “right here, right now”, it processes with pictures and learn physically based on our movements. She compares the right hemisphere to a “parallel processor”, whereas she compares the left hemisphere as a “serial processor”. Taylor defines the left hemisphere

Another visual condition that has intrigued the neurologist for over a century is a condition called visual neglect. After having a stroke in her parietal lobes in her brain, Peggy Palmer had normal vision, which should allow her to draw a copy an image without difficulty. When Peggy was asked to draw a copy of a daisy, they found that she only would draw the right half of the daisies image. She didn’t realize this until the it was told to her, then she could see that she in fact was missing the entire left half of the daisy. Dr. Ramachandran explains that as we see an object, the visual input will split into two different pathways. One is the “how?” and the other is the “what?”. The “how” deals with the area of the brain that mainly controls

In some case patients may have more than just these symptoms such as paralysis or weakness on the right side of the body, vision on the right maybe limited or decreased (hemianopsia), object recognition (apraxia), memory of said words, etc. These symptoms vary according to the area of injury.

The brain assymetry experiment is to investigate on the distinctiveness of the right and left hemisphere in the brain as each hemisphere has certain specializations. The experiment were carried out by initially asking the 25 participant on whether they were left or right handed and they had to choose the chimeric image which appeared younger to them. Laterality quotients were calculated in order to deduce the effect of the right or left hemisphere on visuo-spatiality as the participants had to make judgements on the faces. Right-handed individuals showed leftward perceptual bias compared to left-handed individuals, indicating that the right

Prism Adaptation is a treatment introduced under the theoretical account of a representational model of hemineglect. A representational model of hemineglect is a model in which suggests that there certain brain functions that control both visual imaging and perception (Ogden, 2005).

Impairments in selective attention can cause significant problems for individuals and hinder their ability to attend to relevant stimuli. Studies suggest that the right hemisphere is significant for selective attention (Myers & Blake, 2008). In regards to Phillip, his difficulties include selective attention for objects in space, facial recognition, constructional disability, and dressing disturbances. These difficulties are all due to right hemisphere damage. In particular, constructional disability shows us that the right hemisphere influences visuospatial tasks resulting in the patient’s inability to copy or draw simple figures (Walker-Batson Notes, 2015). Dressing difficulties are related to neglect and spatial deficits. The patient with dressing difficulty may not be able to dress him or herself, as they are unable to reach the contralateral side of their bodies (Myers & Blake, 2008). Facial recognition deficits or prosopagnosia are also common in right hemisphere damage. Phillip might have trouble recognizing family people by their facial features and will only be able to identify them after they speak or by observing their gain or clothing style (Brookshire,

The haemorrhage occurred in the frontal lobe of the brain; the area closest to and impacted by the haemorrhage is the Broca’s area. The Broca’s area is considered the motor speech area, which enables the body to coordinate muscles involved in speech production (Marieb, 2013). Damage to the Broca’s area may result in symptoms that impact the ability to communicate; damage to the area doesn’t affect the ability to decipher language, but presents difficulty for communicating, as it impacts the ability to speak, type and use sign language (Marieb, 2013). The symptoms experienced by damaging the Broca’s area reflect the symptoms experienced by John; Judy described John as having trouble communicating and forming fluent sentences after the fall.

In the second test, the experimenters found that while both sides of the brain could recognize an object via touch, only the left hemisphere can articulate it into spoken words. The right side can only express through nonverbal means. In the third test, both sides of the brain were able to identify objects that either is what is described or associated to what is described by the experimenter. From these tests and some others, the researchers were able to discover that each hemisphere of the brain is able to act independently within the confines of their confines. Both the left and hemispheres are able to processes the senses and have motor functions. However, each hemisphere has its own particular aspects that it specializes in; for example, the left hemisphere specializes in speech, while the right hemisphere specializes in spatial skills. As a result of this study, many other studies have been performed to determine the extent of the two brain theory. After these studies, the psychology community has adopted the concept that each hemisphere of the brain specializes in certain skills and functions but can also think on its own. This knowledge also has a more practical usage. Medical professionals and rehabilitation centers can utilize the knowledge of what part of the brain controls what to better help individuals recover from brain damage by knowing what to focus on during recovery and

everything to the right of a point goes to the left brain, the dominant hemisphere for

A theoretical delineation between intentional and unintentional inhibitory control (Harnish, 1995; Nigg, 2000) further deepens the possibility of a vast array of cogs in the machinery of inhibition and control. Harnishfeger argues that a gate exists in the mind that, without conscious reason, filters information seeping into consciousness. Word ambiguity (Swinney & Prather, 1989) and loss of memory brought about by retrieval functionality (e.g., Anderson et al., 1994) support the notion of unintentional inhibition. In such cases, prior information is automatically and unconsciously

Hematuria is blood in the urine. It can be caused by a bladder infection, kidney infection, prostate infection, kidney stone, or cancer of the urinary tract. Infections can usually be treated with medicine, and a kidney stone usually will pass through your urine. If neither of these is the cause of your hematuria, more tests may be needed to identify the cause your symptoms.

Left-right brain dominance is about the fact that the distinct hemispheres influence thinking. The left hemisphere is associated with logical, analytical thinking and a linear approach to problem solving. The right hemisphere is associated with creative, intuitive and value-based thought process. It is important to note that everyone uses its both hemispheres, but to varying degrees. Four quadrants of the brain, related to different thinking style, have been identified:

Hemodialyis, also known as kidney dialysis. Hemodiaylsis is the most common way to treat advanced kidney failure. It helps to carry on with life even with you have failing kidneys. If you have a need for dialysis you are to follow a strict schedule, take medicines, and to follow a strict diet. The procedure can take place at home or in a dialysis center. You will either sit or recline in a chair while your blood flows through the dialyzer. A dialyzer is a filter that acts as your kidney to cleanse your

Hematite finally realized that the dog from earlier must be hers, which would explain its unusual behavior. She was unable to ponder about its whereabouts as the gem rushed towards her, Hematite quickly brought her machete in front of herself to shield herself from the attack, her stance wide to brace the impact. "I don't have your dog," was all she managed to say before sweeping at the gem's legs in an attempt to knock her

There are many risk factors when it comes to Hematuria. There isn't a specific age range or gender when it comes to being diagnosed with this disease. However, depending on the associated risks such as being less than forty years of age, any history of tobacco usage and pelvic radiation, any infections, being male, or being diagnosed prior to a urological disease, may trigger your chances on getting hematuria.
