What are the different types of adult brain tumors and how are they caused? How are brain tumors treated? Brain tumors are treated by surgery or chemotherapy. Surgery is a very common treatment for primary brain tumors.Sometimes it takes a lot of time to fully take out a brain tumor because not all tumors can be fully removed. Which means that a surgeon will have to attempt to reduce the tumor’s size. How are brain tumors caused? Brain tumors are caused by some genetic diseases which put you…

In the film, Elf, Buddy, a human raised by elves, never quite “fits in” with those around him. As he leaves the North Pole in search of his father, he acts in a rather distinct manner. Thus, in Elf, as directed by Jon Favreau, Buddy’s interactions with others and his surroundings highlight his unique identity. Being a human in the elf-dominated world, Buddy undoubtedly stuck out physically. He was several feet taller, he was heavier, and he struggled to cope in the petite elvish world,…

The field of neuroscience has come a long way from the physical study of the brain by way of dissecting the deceased or experimenting on live animals, to today’s age where one could see the brain in real-time via functional magnetic resonance imaging (fMRI). The fMRI is a noninvasive technique that provides images that detects the changes in blood flow that in parts of the brain that are more active than others. The information can then be compared to existing anatomical knowledge of the brain…

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…

though the cause-effect relationship may not be able to be established because of the complexity of the structure of the brain. There are different types of brain-imaging technologies. For example, the PET(positron emission topography), the MRI(magnetic…

hemoglobin increases the MR signal but because it displaces the deoxygenated hemoglobin that had been suppressing the MR signal intensity . The change in the MR signal, because of the neuronal activity is termed as Hemodynamic Response (HDR). Functional Magnetic Resonance Imaging (fMRI) is a technique used to visualize…

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…

Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards.…

Disaster plans are a very important part of designing a security plan. Disasters come in several types. There are physical disasters like earthquakes, tornados, hurricanes, and floods. Then you have non-physical such as data breaches and system failures. In order for us to complete our security plan we need to create a disaster plan to help us should an unfortunate event occur. The first step in creating a disaster plan is to conduct a business impact analysis (BIA). To conduct a BIA, we must…

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…
