Single photon emission computed tomography

increased inferior frontal gyrus activity compared to those who did not respond, and days later, they also had decreased medial temporal activity. The prediction is that while both the responders and non-responders showed changes in a Single-Photon Emission Computed Tomography (SPECT) image, the responders had more normalization of blood flow (Teneback et. al, 1999). These results support the idea that depression can be caused by either hyper-activation or hypo-activation, an imbalance within the brain

A major proportion of AMI occur in plaques that have not revealed clinically prior to the infarction, that is have not initiated adequate degree of luminal obstruction results angina, which obfuscates screening and interventional primary preventive procedures (38,44,45). Plaque distraction is the core remarkable reason of AMI. The procedure there the fibrous cap of a plaque ruptures plus reveal the blood for primary pro-thrombotic yields and following thrombus development is convoluted (39,44). Lessened

Pierre Marie, a French neurologist was one of the first to describe the conditions of what is now known as Foreign Accent Syndrome in 1907. His descriptions came from a patient who began to speak French with an Alsatian accent after suffering from a stroke. In 1919, twelve years later, a neurologist named Arnold Pick from the Czech Republic, reported a case where a patient who also suffered from a stroke, spoke the Czech language with a Polish accent. During World War II, 1941, there was another

The equipment does not emit any radiation. Instead, it is able to detect the radioactive energy that is emitted from the injection that was given to the patient. The patient is placed beneath the camera for the scan. For a single-photon emission-computed tomography (SPECT) scan, the camera will rotate around the patient in order to form a three-dimensional image (Radiological Society of North America, 2016). For the highest resolution of images, low-energy, high-resolution collimators are

Empirical theories in criminology and criminal justice are intricate when trying to understand and interpret crimes, and how to effectively respond. Throughout history, many attempts have been made to try and comprehend the causation of crime by researching various theories. In this paper, three theoretically based articles will be reviewed and analyzed. The first article, “Neuroimaging Studies of Aggressive and Violent Behavior”, by Bufkin and Luttrell; which gives current findings and implications

Post-Traumatic stress disorder (PTSD) affects thousands, from abused children to men and women in the military. PTSD can be caused by physical and or emotional trauma, it is not exclusive to one race, gender or age group. PTSD can effect anyone who is exposed to severe trauma and is diagnosed at alarming rates. What neurological damage is caused, where in the brain is this damage caused and how is it studied? With modern science we are able to view how Post –Traumatic stress disorder effects the

Fibromyalgia (FM) is characterized by chronic widespread pain with accompanying symptoms, such as fatigue, morning stiffness, insomnia, cognitive dullness, depression and anxiety 1,2. Not only does FM impair life quality3, but it also increases disability and absence from work4. With the evolving diagnostic criteria of FM5, the prevalence rate is estimated about 2~4% in the general population with female predominance 6,7. Despite genetic, environmental and biochemical factors proposed as the underlying

One man, one brain and one hundred trillion synapse. It takes a moment for one to experience damage to ones brain and neurons within the brain and a lifelong journey of recovery. The brain consists of many neurons which are single nerves. This essay intends to discuss whether there is effective recovery from brain damage by describing the intricate process of neural networks in the brain. It will include the fascinating and continuously evolving process of neuroplasticity. It will elaborate on the

Despite societal expectations of women attending university, Marie Curie’s motivation to expand her knowledge of science drove Curie’s ambition to find a university she could attend. Curie moved to Paris and attending university where she learned French while earning a degree in mathematics and physics. These degrees enabled Curie to investigate uranium and thorium, which later led to studying pitchblende, a natural ore containing these elements (Froman 2014). It was through pitchblende Curie discovered

the human body. These methods employ various scanners like the CAT, PET, MRI and SPECT. The CAT is an acronym for Computerized Axial Tomography. This method of scanning generally involves X-rays and enables scientists to view the inside of the head in a three dimensional format on a computer screen. PET stands for Positron Emission Tomography and it is much more complicated than the CAT scan. PET machines bombard the subject with doses of positrons -- the anti-matter equivalents
