Neuroimaging

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 Functional Magnetic Resonance Imaging has developed in the field of brain mapping came about in the 90s. As mentioned in the scientific literature, neuroimaging data can help map the connection of a specific brain region to a cognitive function; this…

Neuroimaging is a technique that produce images of brain without any direct contact 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…

Developing a method for imaging inside of human body that compromises generality, accuracy and execution speed has been a great issue for the brain science for the last decades. There are many methods imaging structure such as CT, PET, EEG, MEG, fMRI. Recent years have seen impressive improvements in fMRI, and it seems that fMRI is gaining popularity over other methods. Becoming a popular tool for investigations into the neural correlates of cognitive activity and other research, the number of…

technology such as, functional magnetic resonance imaging (fMRI) or positron emission tomography (PET), cognitive neuroscience has been able to demonstrate how cognitive processes may be derived from brain-based mechanisms. The mind can be looked at as the processor that links the input (the sensory information), to the output (the response). So, therefore this essay plans to explain how the brain imaging techniques of cognitive neuroscience can help to understand internal processes of the…

says that the reasons psychopaths cannot feel and use emotions is because “their brains are physically different than a normal persons”. The emotional circuit is what is able to stop a person from breaking into a house or committing a murder, but in people like Dugan this emotional circuit is unable to work. “According to Kiehl psychopaths are like people with very low IQ’s, because people with low IQ’s are not fully responsible for their actions in the legal system.” (Hagerty, “Inside a…

of gray matter where we do much of our conscious and complicated thinking—to become thinner but more efficient. Taken together, these changes make the entire brain a much faster and more sophisticated organ. This process of maturation, once thought to be largely finished by elementary school, continues throughout adolescence. When this development proceeds normally, we get better at balancing impulse, desire, goals, self-interest, rules, ethics, and even altruism, generating behavior that is…

effort than the no-smoking average people. Several studies carried out through fMRI, have evaluated that adolescence that consume high dosage of cocaine tend to develop some deficit in some cerebral region that are involved in focus. Moreover, the indisputable nature of the organic damage caused by methamphetamine (MA) and its derivatives is supported by the numerous findings derived from both structural and functional neuroimaging brain analysis. Adolescents that use methamphetamine and…

advancements and discoveries regarding the brain. For example, today’s brain imaging techniques so were able to see images of the brain 's structure and functions. An example of biological psychologies advancement of brain imaging can be displayed in the research done by Meshi, Morawetz, and Heekeren (2013). Their research studied the neural processing of gains and its relationship to real world behavior through Facebook use. Participants then went through an interview process, personality…

A great example of these improvements is the possibility of diagnosing Alzheimer’s before symptoms occur. An article named “Alzheimer's and Dementia Testing for Earlier Diagnosis” written by the Alzheimer’s Association talks about the huge benefits that come out of targeting Alzheimer's in earlier stages before causing irreversible brain damage. The Alzheimer's Association wanted to find potential biomarkers that will allow to detect early stages of the disease, and so far Brain…

Neuroimaging is defined as a “set of tools that produce pictures, of the brain, sometimes called brain scans” (). There are two specific types of neuroimaging: functional and structural. Functional neuroimaging looks for brain activity by measuring the amount of oxygen that changes in the blood, electrical impulses or chemical activity. Structural imaging generates pictures inside of a head, that includes pictures of bones, brain tissues, blood vessels and fluid of the brain and spine.…
