Measuring Brain ActivityMost of the noninvasive imaging methods estimate superstar bodily function by changes in jumpning flow, type O consumption, glucose utilization, etc. Discuss the potential problems with using this type of verificatory measure.The heading is the control center of the human body. It sends and receives millions of signals every second, day and night, in the form of hormones, nerve impulses, and chemical messengers. This exchange of information makes us move, eat, sleep, and think. Obstructions much(prenominal) as tumors can interrupt habitual brain bodily process, leading to deficits of normal reasoning, motor control, or consciousness. Many of the signs of neural damage are slow recognizable by an outside observer, but since the actual cause of these problems are internal, the symptoms can be vague. The real deficits can affect the brains anatomy, or the way signals are processed. A physician can solitary(prenominal) determine the real cause by exam ining the brain internally to attain irregularities, either in structure or in functioning. Since the brain is exceedingly fragile and difficult to access without risking further damage, imaging techniques are employ frequently as a noninvasive method of visualizing the brains structure and activity. Todays technology provides many useful tools for studying the brain. But steady with our highest technology out there we do non know everything definitely. We do have fallbacks at times and these fallbacks can lead to serious problems. The new advances in non-invasive brain imaging, increased computational power, and advances in signal process 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 brains blood, oxygen con sumption, glucose utilization, and more. These measurements may non be accurate overflowing to figure out one persons problem. The problem once more might be internal and measuring only the obvious would not aid in figuring it all out. Other problems with using these noninvasive imaging methods of only few changes of variables in the brains activity are that maybe the problem does not reside in the blood, oxygen intake, or glucose utilization. It may be in other factors that we do not observe that is causing the trouble. By being limited to these estimations of brain activity does not really make our effort of correcting the problem that successful.
