Download file to see previous pages Now, with the advent of Magnetic Resonance Imaging, and other non-invasive assessment technologies, the less invasive, but more direct and accurate examination of the brain has been made possible. The areas of the brain which now respond and which manage pain perception and sensation can now be laid out and understood by practitioners. The more technical processes of pain sensation and mediation can now be assessed and evaluated. It is popular knowledge that the brain controls and manages all types of sensation and feelings in our body. Understanding the more specific patterns which explain these control functions in the brain are more complicated and need a more thorough analysis. This study shall now seek to discuss how the brain mediates and controls the sensation of pain. It shall first present an anatomical discussion of pain sensation, and then a deeper analysis of brain mediation and control of pain shall be carried out. An emphasis on the central mechanisms of pain and the biological and neurochemical processes underlying them shall be presented in this paper. This study is being undertaken with the purpose of establishing a clear and comprehensive understanding of the brain functions as it mediates and controls pain sensations. ...
In effect, sensitized nociceptors can cause secondary shifts in the central activity processing which causes hyperactivity, making input from the A? fibers to be felt as pain (Baron, 2000). As a result, these patients spontaneously experience pain alongside sensitivity to heat. A similar analysis by Pawl (1999) discussed pain as assessed by the brain through function images. In his analysis, he was able to confirm that during the pain experience, increased activity in the sensory pathways from the thalamus to the sensorimotor cortex was apparent. Pawl (1999) also established that the contralateral hippocampus became active during experimental heat pain; during acute pain, activity in the amygdala was also increased. In studies covering chronic pain, the nociceptive disruptions often activated the same areas; but these same areas were manifestly less active in instances of pain which originated psychogenically (Pawl, 1999). This analysis implies the more apparent pathways for pain depending on the kind and the source of pain. Based on the analysis by Yaksh (1999), the regulation of afferent processing is at the level of the spine. Yaksh analysis is more detailed in terms of the involvement of the NMDA and the NKI receptors. Aside from systems which can reduce excitability, the post-tissue injury pain condition is marked by the upregulation of gain. As a result, continuous small afferent excitation triggers a cascade which is instigated by the release of amino acids and peptides. With the activation of the NMDA and NKI receptors, there is a rise in intracellular calcium and the stimulation of the kinases and the phospholipase A2 (Yaksh, 1999). The NMDA then acts as the phosphorylate membrane channels and receptors; while the NKI causes the ...Download file to see next pagesRead More

Sensation and Preception

...of there being no actual difference, aside from the center boundary, we still get the sensation that there is a slight difference in brightness or color. This phenomenon, referred to as subjective contours, is explained as the brain’s tendency to detect a slight difference in the sensory stimuli, in this case the slight color variation, and to over-extend that variation, therefore registering a pattern that does not exist. This highlights the internal influences on our perception, such as prior experience, expectation, and bias, on what is external. Studies have revealed that previous experience and expectation play a significant role in sensation and perception of sensory stimuli. One...

How music affect the brain

...other sense. How brain understands music Music is a kind of perpetual illusion, similar to how a collage is perceived. The order and structured is imposed by the brain over a sequence of sounds that helps establish a completely different system of meaning. Understanding of the underlying structure of music plays a very important role in determining an individual’s ability to appreciate music. This includes the ability to predict the subsequent rhythm and lyrics in a song. Skilled composers control the emotions evoked by a song through an understanding of the expectations of their audience. Successful manipulation of these characteristics of a song...

Pain the nervous system while nociceptive is usually activated by nociceptors affects the bones, blood vessels, tendons and muscles. Similarly, in nociceptive pain, stimulation in the nociceptors causes a person to experience visceral pain that comes from the viscera or organs. The organs undergo a sensation that spreads to the spinal cord or brain that also affects the peripheral nervous system. There is also anxiety sensitivity (AS) that generates bodily sensations thus causing pain-related fear that initiates avoidance or escape in the person. According to psychologists and theories, elements of AS in the human body system aggravate the...

How spanking harms the brain

...some inferiority among children who experienced physical punishments. Although the idea before was concentrated more on the psychological effect of punishment, the research could be the missing link that would point out or explain the inferiority complex in victims. It is indeed a moral and social responsibility of parents to discipline their children however it does not mean that they have to result to corporal punishments rather can use a lot of love, patience and communication. Patience is definitely essential in parenting coupled with love because children can simply be challenging sometimes. Speaking with them in a matured manner can express trust, love and encouragement.

Sensation & Perception

..., the color blue is particularly meaningful to me, or I ‘perceive’ this color as special from the rest because every time I am wearing blue I usually get what I wanted. Call it luck, but it is true for me. According to some psychologists, many people like the colors red, green, and blue because we have special ‘cones’ that immediately recognize light waves for these three colors (Nicholas, 2009). But different people perceive different colors differently, because of what they call ‘perceptual expectancy’ (Weiner, 2003). I define this as perception that is based on our experiences and biological tendencies. But what interests me most with regard to sensation and perception is the concept of ‘pain’. All of...

How Does the Brain Work

...How does the brain work? This video is one of the many that explore the mystery of information processing by the brain. Despite being an organ that can be held in the hand’s palm, it is the most complex organ with about 100 billion nerve cells or neurons that constantly interact with each other. From Nova scienceNOW (n.p), the operation of the brain is comparable to magic, control and magic mind. Nova scienceNOW defines the brain as being dependent on a single stimulus in order to make its decisions. A single stimulus is determined by the brain evaluating the activity resulting from numerous neurons. Even though the...

Internal Controls

...SONY: Internal Control According to Gilbert, Martin 2004, pp.306, internal control is a process for assuring achievement of anorganizations objectives, operational efficiency and effectiveness, dependable financial reporting, and compliance with regulations, laws and policies. In the case of SONY, some of the aforementioned roles of internal controls have not been achieved as a result of various internal control weaknesses and deficiencies. In the recent story carried by the New York Times, the corporation is at a very high risk of incurring huge losses if measures are not taken to protect the gains that the company has made. Significantly, the company has been marred...

...Statistical quality control Statistical quality control scenario Control limits Upper control limit = 6.33 + (0.06/ (3)1/2) = 6.43 Lower control limit = 6.33 - (0.06/ (3)1/2) = 6.23 The control for the weight of the boxes is not bad off . Each set has three boxes, the first two boxes have weight that are within the weight limit of 6.2 and 6.4 ounces, but the third box to be added to complete the set exceed the limit. This therefore, means the company suffers a loss for those ounces supplied to their clients that have not been paid for. From the X-chart, it can be noted the first box has the lowest weight than the other boxes followed...
