Neuropsychology looks into the brain and what brain damage can be caused by studying the relationship between the brain and the functions. Beaumont (1996) said that neuropsychology is the study of the relationship between the brain and mental life. By bringing ideas from neurology and cognitive psychology it allows analysis of an individual’s abilities and cognitive skills. Neuroimaging has techniques which is able to measure the brain through different scans and images. There are many different techniques used in neuropsychology/neuroimaging that help further our understanding of the brain and how it works, however they all have their faults as well as the positives that they carry. This essay will focus on fMRI, TMS and ECG techniques.

These responses would come from the person’s sensory and motor activation, visual imagery tasks and language tasks. Although the fMRI technique uses the same equipment as a MRI scan, it records new information compared to the MRI which leads to the fMRI been the most popular choice. There are two main ways in which the experiment can be carried out, one being the block test which involves the patient carrying out a test then has a rest and repeats this a number of times. However the patient can easily get bored with this and this can cause restlessness. The other is an event-related design and although this is better for the patient as it causes less boredom it can take much longer to carry out. There are many benefits of using an fMRI technique one of these being that while we are studying the live brain it can create a special resolution of one to two millimeters which has been said to be the best resolution that any technique can produce along with the temporal resolution which is said to be as little as 1 second. This has allowed for our knowledge of the brain to be expanded which has led to some discoveries which has advanced our research. Cohen and Bookheimer

    Other testing procedures that are commonly employed, in order to gain a better visual image of the excitatory activity in the brain are the PET scan and the MRI. According to Kalat (2004), these methods are non-invasive, meaning that they don’t require the insertion of objects into the brain, yet they yield results that allow researchers to record brain activity. The PET scan (positron emission tomography) involves the researcher injecting a radioactive chemical into the patient’s body, which is then absorbed mainly by the brain’s most active cells. With the use of radioactive detectors, placed around the patient’s head, a map is produced that shows which areas of the brain are most active.

    Prefrontal Cortex The prefrontal cortex is the most anterior portion of the frontal lobe. It responds mostly to stimuli signaling the need for movement, however it is also responsible for many other specialized functions. It receives information from all sensory systems and can integrate a large amount of information (Kalat 2004). Studies have shown that the prefrontal cortex is responsible for working memory. Working memory is defined as "the information that is currently available in memory for working on a problem" (Anderson 2005).

  • A Deep Dive Into The Brain Analysis

    In the article “A Deep Dive Into the Brain, Hand-Drawn by the Father of Neuroscience,” the author, Roberta Smith, praises the 80 freehand renderings of the neuroanatomist and artist Santiago Ramon y Cajal. Although a regular art critic for the New York Times, Roberta Smith has nothing negative to share about the exhibit “The Beautiful Brain: The Drawings of Santiago Ramon y Cajal.” Smith leads her readers through a vivid description of the impressions a viewer experiences from Cajal’s artwork. Nevertheless, the attentive reader notices Smith’s passion about Cajal’s work as both a neautoanatomist and artist and senses her struggle to find the words to express that passion. Consequently, the author boasts about Cajal winning the Nobel Prize,

  • Comparing Two Approaches to Cognitive Psychology

    1413 Words  | 3 Pages

    Historically, cognitive psychology was unified by an approach based on an resemblance between the mind and a computer, (Eysenck and Keane, 2010). Cognitive neuroscientists argue convincingly that we need to study the brain while people engage in cognitive tasks. Clearly, the internal processes involved in human cognition occur in the brain, and several sophisticated ways of studying the brain in action, including various imaging techniques, now exist, (Sternberg and Wagner, 1999, page 34).Neuroscience studies how the activity of the brain is correlated with cognitive operations, (Eysenck and Keane, 2010). On the other hand, cognitive neuropsychologists believe that we can draw general conclusions about the way in which the intact mind and brain work from mainly studying the behaviour of neurological patients rather than their physiology, (McCarthy and Warrington, 1990).

  • An Evaluation of Case Studies and Their Contribution to Cognitive Neuropsychology as a Discipline

    2094 Words  | 5 Pages

    Cognitive psychology is the study of the brains internal processes that guide behaviour; to study cognition, psychologists examine case studies of patients with damaged brains that can infer areas, and functions involved in particular processes. Patient studies have provided insights into the processes that take place within our minds, and have enabled psychologists to create models, which can be tested and fractionated. Cognitive neuropsychology has developed from cognitive psychology to become a discipline in its own right; it investigates the function and structures of the brain involved in cognitive processes and should not be confused with cognitive neuroscience, which is primarily concerned with neural structures and their functions.

  • measuring brain activity

    536 Words  | 2 Pages

    The recent advances in non-invasive brain imaging, increased computational power, and advances in signal processing methods have heightened the research in this area. As we make progress in interpreting noninvasive brain signals in time we will begin to explore applications that go beyond treatment. But for now these noninvasive methods of estimating brain activity is still something to be cautious about since it only measures the brain’s blood, oxygen consumption, glucose utilization, and more. These measurements may not be accurate enough to figure out one person’s problem. The problem again might be internal and measuring only the obvious would not aid in figuring it all out.

If we could pick one mystery in the world that people really want to know about, that would be of God within the confines of science. It could help explain or at the very least grasp a better understanding of how and why people all over the world believe in a higher power and feel the need to worship something. Some other finding not even related to religion maybe discovered.

    The nervous system is composed of all nerve tissue in the body. This organ system forms a communication and coordination network between all parts of the body. It plays a major role in everyday activities such as breathing, walking even blinking. It is made up of nerve tissues to receive and transmit stimuli to nervous centers and initiate response. Neurons are nerve cells that transmit signals from one location of the body to another. With damage to the nervous system the body would not be able to function properly. The body has to be well taken care of in order to insure proper regulation. The two anatomical divisions that work hand in hand to help regulate the nervous system are the central and peripheral nervous system. According to the Campbell’s seventh edition biology book the nervous system is the most intricately organized data processing system on earth. It is a complex collection of nerves and specialized cells.
