There are numerous ways in studying methods of the brain. It ranges from electrical and chemical stimulation‚ recordings of the electrical activity from the brain‚ scanning and imaging techniques‚ and so on. The effects of electrical and chemical stimulation take place within different places in the brain that selectively affect specific psychological processes as well as psychologically active medications; anesthetics and recreational drugs). These selectively affect different mental processes

transhepatic cholangiography is particularly useful in patients with bile duct strictures and tumors‚ as it defines the anatomy of the biliary tree proximal to the affected segment (Funaki‚ 2007). 7. Magnetic Resonance Cholangiopancreatography (MRCP) Using magnetic resonance imaging (MRI) with newer techniques and contrast materials‚ accurate anatomic images can be obtained of the bile ducts and the pancreatic duct. It has a sensitivity and specificity of 95 and 89 percent‚ respectively‚ at detecting

subject’s score of 112. This showed no significance; suggesting superior memory is not due to general intellectual abilities. The theory whether this superior memory was caused by structural differences in the brain was tested using structural brain imaging. The results produced by the voxel-based morphometry showed there were no significant differences in brain matter between the control subjects and the superior memorizers with a P-value of 0.05 and 0.005. These results also showed no significant

Patient scenario The patient Mr. Smith was diagnosed with prostate cancer 5 years ago. It seemed as if his condition was worsening so he visited his physician who performed a physical examination on him. A physical examination has many components they include observing the signs of a disease by checking for signals like change in skin pigment or alertness. Then there is checking vital signs such as blood pressure‚ heart rate and temperature by comparing your results to a standard. Next step the

Then‚ choosing just one technique‚ discuss how this has been used to address one aspect of cognitive psychology that interests you. Functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) are two techniques commonly used to noninvasively examine functions within the human brain. When independent of one another these methods fail to provide sufficient information to understand the spatio-temporal

Cocker and Walton Prizes 2012 Physics in Medicine By Fayaz Rahaman ➢ Introduction Physics is about understanding the laws that govern the world around us. Most people know about the problems solved and the discoveries made by physicists in the past‚ such as the orbits of planets found by Galileo‚ the law of gravity first unravelled by Newton and later extended by Einstein. It is not as widely

The capabilities of a magnetic resonance imaging (MRI) has been improved through the application of digital signal processing (IEEE‚ 1999). 3. Digital Signal Processing plays a big role in medical field (Ifeachor‚1996). B. Military technology such as radar has been improved by

Pacemaker The human heart is an essential organ of the human body. Its sole purpose is to supply the body with oxygen by pumping blood through a complex system of veins and arteries. However‚ it is often common for the human heart to suffer from various heart conditions‚ such as a heart block‚ slow heart beat‚ heart attack or heart failure. Such heart conditions can lead to weakness‚ fainting‚ shortness of breath‚ or even possibly death. These can usually be treated with medication but in cases

The second section of this paper critique’s an article entitled “Overactive Action Monitoring in Obsessive-Compulsive Disorder: Evidence from Functional Magnetic Resonance Imaging”. This section includes the discussion on how the anterior cingulate cortex has been found to be hyperactive in those with OCD. Testing for this study was using FMRI’s. The

When young men who don’t normally play a lot of video games are exposed to violent video games‚ changes occur in the way their brains function‚ new research shows. Using functional magnetic resonance imaging‚ the scientists conducted that document altered brain response time after playing these video games. A lot of these changes had affected them in the long term also. It is proven that video games do have an affect on your brain‚ but it
