Magnetic tape

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.…

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…

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…

This all changed in 1951 when the UNIVAC 1 was created with magnetic tape storage. The computer was able to store tons more date in was less space. The magnetic tape worked in the same way that a music or audiotape worked. The small compact design and tons of tape rolled into the small plastic tons of bites of data could be stored. This was revolutionary for the computer improving many aspects like size, weight…

IBM 701 still used a vacuum tube circuitry but used magnetic memory storage and could hold a maximum of 2048 words. Although it was relatively cheaper compare to the ENAIC, it still cost $4000 at the time and $35000 adjusted for inflation. Transistor was the first major breakthrough for electronic computers…
