Functional magnetic resonance imaging

tell from its discovery when its fundamentals originated as NMR (Nuclear Magnetic Resonance) and its leaps forward have saved thousands of lives and yielded 5 Nobel Prizes in the process. [12] [15] The story of the origins of MRI begins over 130 years ago whom can only be described as one of the most amazing pioneers in physics today. Nikola Tesla discovered the phenomena of Rotating Magnetic Fields. This is when a magnetic field that rotates around a central position along some axis with…

the individual. According to Haran, a few medical tests can be conducted to properly examine and investigate the possibility of possessing paedophilia. For example, IATs (Implicit Association Tests), phallometric testing, and fMRIs (functional magnetic resonance imaging). These tests can help to detect any abnormalities or disfiguration regarding the individual’s brain. A paedophile’s brain has been concluded to have retardation on the frontal cortex and the grey and white…

The popular science article “You May Be Able to Train Your Brain to Be Fearless” published by The Huffington Post discusses the study “Limbic Activity Modulation Guided by Functional Magnetic Resonance Imaging–Inspired Electroencephalography Improves Implicit Emotion Regulation” conducted by Dr. Talma Hendler. I find that the pop science article doesn’t portray the information correctly. It fails to include terminology and key results; specifically, the downsides of the study. The article’s sole…

The best imagining device that would be best to use to localize the tumor in the man’s brain is the MRI. This is because the MRI, which is also known as the Magnetic Resonance Imaging, is a scanner that uses a powerful magnet and radio waves linked to a computer to create remarkably clear and detailed cross sectional images of the body. The MRI machine can be used to view, monitor or diagnose various things. It can be used to identify and monitor abnormalities of the brain and spinal cord, and…

Following the introduction of the brain-disease model of addiction, proponents and opponents have emerged to argue for or against a neurocentric view of addiction and the importance of brain circuitry in treating addiction. The following discussion will discuss the societal pros and cons of labeling addiction a brain disease and evaluate whether brain circuitry is necessary for the treatment of addiction in order to illuminate the benefits and drawbacks of the brain-disease model for individuals…

with the inside of the body such as internal surgery, incision of the skin. Neuroimaging technology become a powerful tool for both research and medical diagnosis. Because these technologies enable noninvasive visualization of the structure and functional segments of the brain. The field of neuroimaging has advanced rapidly day by day due to the development in technology and computational methods. The applications of neuroimaging techniques become far-reaching. Brain is the most important and…

Introduction: Head motion is one of the major sources of artifacts in functional Magnetic Resonance Imaging. Head motion is said to cause large spatially varying changes in the signal intensity of the BOLD signal, making it very difficult to separate neuronal activations from the motion artifact. Realignment corrects the changes in brain position, but it does not take into consideration the changes in the image intensity associated with motion. Head Motion, particularly in the direction…

image analysis plays a vital role in medical diagnosis is a broad area of education and research attention. Medical imaging techniques become a nature look with different characteristics depend upon the selection of modalities with the requirements ( Li Luo 2007). For example, CT offer supreme information on denser tissue with smaller amount distortion whereas Magnetic Resonance Image (MRI) offer superior information on soft tissue with supplementary distortion (Yong Yang et.al. 2010) and…

tumors, being the third location after liver and lung [5]. Bone metastases are a major clinical concern as they can deteriorate the bone structure causing pathological fractures, vertebral/spinal instability, severe pain, spinal cord compression, functional impairment and increased mortality. The vertebral column being the most frequent site of bone metastasis and one of the major organs in human body strongly correlated to neural and the skeletal system it plays an important role in various…

specific emotion.” (Weiss 453) Everyone knows love exists and it can be measured and analyzed. Love is a real thing. The concept of sexual desire and romantic love are intertwinded. These researchers analyzed the twenty seperate Functional Magnetic Resonance Imaging Scans trials of subjects engaged on tasks. The trial subjects engaged in looking at porn, and photos of significant others. Photos of their acquaintances non pornagraphic. Researchers were able to show the subjects how these…
