Essay Assignment II Nov. 28th‚ 2012 Discuss whether the functional Magnetic Resonance Imaging (fMRI) is a new form of “phrenology”. Is it reliable enough to be used as evidence in court? After fMRI was first introduced‚ it has been under criticism that it is not hard science. The most common technique‚ the BOLD (blood oxygen level-dependent) fMRI‚ measures the increase in regional cerebral blood flow in response to increased metabolism‚ which is to be caused from heightened activity of neuron

Magnetic Resonance Imaging (MRI) and Computed Tomography Scan (CT) Modern medical technology allows physicians to capture detailed images of the body for diagnosing and treatment planning of various health issues. Radiologists use imaging technologies to diagnose or treat diseases. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. Acquisition of medical imaging is usually performed by a radiologic technologist and the results are interpreted

Introduction A sample of DNA found in a crime scene was provided along with five suspects. Their DNA was then processed using restriction enzymes and Agarose Gel Electrophoresis. The objective of this lab was to match a criminals DNA to a crime scene using restriction enzymes EcoRI and Pstl with Agarose gel electrophoresis. Restriction enzymes cut DNA at a specific base pair site recognized by the enzyme‚ which then turns one single strand of DNA into many fragmented strands of DNA. EcoRI recognizes

Brain Imaging Technologies in Research of Biological Factors and Behavior Within the biological level of analysis there are many different technologies used when investigating the relationship between biological factors and behavior. There are five main technologies‚ however‚ functional magnetic resonance imaging (fMRI) and magnetic resonance imaging (MRI) are the most common ones. These are based on the fact that when the body is exposed to a magnetic field‚ the protons in the body fluids

Research Critique of " Molecular Gastronomy: Cuisine Innovation or Modern Day Alchemy?" Villongco‚ Jocen Q. De La Salle – College of Saint Benilde July 9‚ 2012 Abstract This paper aims to explore the phenomenon of molecular gastronomy by conducting empirical research focusing on renowned chefs. The approach taken is a literature review summarizing past culinary innovations by great chefs over the last 300 years. The concept of Nouvelle Cuisine was highlighted as the latest gastronomic

to an area of low concentration. How quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances. The methylene blue and potassium permanganate (KMnO4) was used and placed in the plate. Because the two substances have distinct colors‚ the

Low Molecular Weight Heparin Paper Low molecular weight heparin is typically used for patients who need to be treated for deep vein thrombosis. Deep vein thrombosis (DVT) is a blood clot (thrombus) in a deep vein usually in the legs. These clots are dangerous because they can break loose‚ travel through the bloodstream to the lungs‚ and block blood flow in the lungs (pulmonary embolism). There are many reasons why clots form in a patient. Mainly

HOW CAN BRAIN IMAGING HELP STUDY COGNITION? Intro * involves analysing activity within brain while performing various cog tasks – allow us to link bhvr & brain function to help understand how info is processed * cog activity assoc w neural activity in brain regions: * on scalp as electrical activity ie MEG‚ EEG (direct measures) * inside brain by measuring O2 consumption caused by neural activity ie PET‚ fMRI (indirect) * diff imaging techniques vary in their temp (time-based)

brain imaging technology (BIT’s) enable us to investigate the relationship between biological factors and human behaviours in greater depth. BIT’s are used to move away from more invasive techniques of studying the brain‚ such as liasoning - intentional scarring of the brain‚ and ablation - intentionally cutting out pieces of the brain. The brain imaging technologies that will be examined are electroencephalography (EEP)‚ functional magnetic resonance imaging (fMRI)‚ magnetic resonance imaging (MRI)
