Magnetic resonance imaging

With music, you experience something that is encoded into our bodies and our brain. It goes directly to a part of the brain that stimulates our emotions. Music starts affecting humans at an early time. The human fetus begins to hear when they are 17 to 18 weeks old. Music is energy. People that can not hear can still feel the music with vibrations. Every object has the capacity to send waves or vibrations. Vibrations make the music go into the brain by sending waves. An electrical charge…

Stacy Deveau CJ 521-031 Doctor Siegel November 9, 2014 Genetic Neural Sonar and its Positive Attributes to Society The mapping device known as the Genetic Neural Sonar has been actively tested and used from Yale University Medical School. This device has the capability of locating inherited gene base abnormalities in brain structure and chemistry. This mapping device could and would be used to map the brain genetic structure and determine if an individual has…

The article I chose to explore and summarize for this assignment was ‘Voluntary attention modulates fMRI activity in human MT-MST’, by O’Craven, K.M., Rosen, B.R., Kwong, K.K., Triesman, A., & Savoy, R.L. The basic theory behind this study is that the visual system receives copious amounts of information. Attention permits the visual system to pinpoint a “subset” of that information for further processing and attention, dependent on either the properties of the stimulus (bottom up processing) or…

A study conducted by the Cincinnati MR Imaging of Neurodevelopment (CMIND) Authorship Consortium on 23 healthy, right-handed children, ranging from ages 7-9, calculated the relationship between reading comprehension (right hemisphere) and language comprehension (left hemisphere). With the use of Diffusion Tensor Imaging and fMRI, the researchers were able to measure brain activity during a Sentence Picture Matching task. The researchers…

Peripheral artery disease (PAD), also known as arterial occlusive disease, is the obstruction or narrowing of aortic passages--including lumen and its major branches. This blockage interrupts blood flow, usually to the feet and legs. The prognosis will vary depending on the occlusion's site. The symptoms vary depending on the location of the occlusion. For example: in femoral arteries, having pain in the feet, no pulse in ankles and feet, and pallor or coolness in legs are symptoms.…

The development of the MRI (Magnetic Resonance Image) machine has changed the medical world for the better. One of the first points about the MRI is that it was created by Professor Raymond Damadian in 1977. The first time the MRI machine was used, it took a total of five hours to do the whole scan. Also, the first MRI machine ever used is now in the Smithsonian Institute, and was nicknamed the “Indomitable.” Many people think they know what an MRI machine does, but most of the time they are…

I is a great tool for medical imaging and widely used for MS, but it has some limitations in lacking specificity and MRI not capturing diffuse white matter pathology 1. New emerging techniques such as transcranial magnetic stimulation (TMS) and optical coherence tomography (OCT) for monitoring visual impairment by MS have the potential to address issues not resolved by current MRI techniques. TMS is a new method not widely used yet, but suitable to detect the conditions affecting MS patients.…

Cognitive psychology is the study of human mental processes that occur within the mind. It looks at such internal processes such as, memory, perception and attention. It came about in the 1950’s as a result of the behaviourist approach being flawed; internal mental processes cannot be observed. Therefore, from this an alternative method of looking at the physiological side of the brain had to emerge. Cognitive neuroscience was then born to identify the neural mechanisms, which are responsible…

Started from 1895, when Wihelm Cornrad Roentgen discovered X-rays, numerous groundbreaking findings laid the foundation for medical imaging (Riesz 1995). Since the beginning of the twentieth century, many medical imaging modalities have been used in routine clinical practice to obtain anatomical and physiological information. PET, for instance, is used for physiological imaging. Ultrasound, MRI and CT are commonly used for soft tissue structures (Weissleder and Pittet 2008). In oncology, the…
