  • Cognitive Neuroscience Study

    the neural mechanisms, which are responsible for underlying cognition. These neural mechanisms are also important when it comes to manifestations in behaviour. Cognitive neuroscience helps to combine the works of cognitive science and cognitive psychology. However, it is important to consider how internal physical processes can initiate mental processes. Recently, cognitive neuroscience has introduced methodological advances that enable experiments to be taken place safely in a laboratory.…

  • Functional Magnetic Tolerance Imaging Device Analysis

    Like any other cells in the body, when neurons are activated they consume glucose and oxygen to fuel their activity and they produce metabolic waste. According to Sadock, Sadock, and Ruiz (2015), a functional magnetic resonance imaging (fMRI) device works from this principal by using high magnetic fields and radio frequencies to indicate activity. The fMRI helps the medical professional to peer into brain activity, not by measuring brain activity directly, but by observing the flux of oxygen…

  • The Importance Of Medical Oncology

    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 integrated examination (PET/CT) has gained widespread acceptance as a tool for diagnosis, staging, prognosis, treatment…

  • What Are The Disadvantages Of The Pop Science Article

    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…

  • Medical Imaging Characteristics

    Medical 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 2010) …

  • Paedophilia Case Study Essay

    lobe of the brain. The cause could be a result of either a birth defect or even due to any sort of accident acted upon the cranium of 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…

  • Neurosimaging

    In the past three decades neuroimaging has revolutionized the world of neural sciences. First, it was the introduction of the computerized axial tomography in the 70s that gave information of anatomical structure. In the early 80s, the development of positron emission tomography gave the neural sciences the ability to produce 3D images of functional processes and magnetic resonance imaging provided an alternative to CT and X-ray imaging without the radiation exposure. Lastly, the domination that…

  • Diffuse Optical Tomography Essay

    Diffuse Optical Tomography is non invasive, non ionizing functional imaging modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured.…

  • Love Is The Beauty Of The Mind

    associated with activation of dopamine-releasing regions in the brain.” (Weiss 453) Like the striatum which is the pleasure center of the brain. The dopamine in the brain helps display various feelings. Therefore triggering the part of the brain that displays motivation. Hence the reason people think its a goal oriented state. The insula part of the brain “gives value” to all pleasurable activities. The research study concluded that this love is in essence a “goal-oriented motivation state…
