Introduction

There are many techniques that are being used today to examine the functionality of the human brain. Most of the current technologies emerged in early 1990s. Some of the technologies that are used for brain imaging include; computed tomography (CT), positron emission tomography (PET), Magnetic resonance imaging (MRI), event-related potentials (ERPs) and magnetoncephalography (MEG). This paper will look at the history of these techniques used for brain imaging(Katz & Alexander 1994).
1895 – 1900 Early uses of brain imaging
The process of imaging human dieses started in 1895 following the discovery of Wilhelm Roentagen. He was a physicist that ...

Introduction

Magnetic resonance imaging (MRI) is referred to as a test that makes use of the magnetic field as well as the radio waves in order to produce the pictures of organs of the body. It also produces the structures of the of the body (Pettersson 1998). It has been found out that MRI normally produces pictures of the organ of the body in a very different manner. However, it differs with some techniques such as X-ray, ultrasound or computed tomography. MRI again can produce some problems which might otherwise not be found using other techniques already mentioned. Image quality of MRI ...

This paper seeks to establish the use of technology in the investigation of cognitive processes. Cognitive processes are the mental functions of intuition, sensing, feeling and thinking. These functions divide along the lines of; processes of perception and processes of judgment. Sensory and intuitive processes help the brain in perceiving the environment and collecting information. Thinking and feeling processes apply in making appropriate decisions as may be required of the situation.
Owing to the immense value of cognitive Processes to humanity, it is important that they are apparent. The use of technology has changed the manner in which ...

I am a Magnetic Resonance Imaging technician (MRI Technician). My career involves using magnetic fields and radio waves to get images of tissues and systems of organs in order to search for or diagnose illnesses. My job entails preparing patients for MRIs, management of schedules, reporting and interpreting findings to doctors. I work in a hospital. In addition to the mentioned duties, I also move heavy equipment and assist patients to get into position for the procedure.
Like any other job, being an MRI technician comes with a myriad of challenges and ethical dilemmas. Most imaging departments are always busy. We ...

Introduction

Fourier analysis is a field of mathematics that studies how general functions can be approximated or represented by the addition of simple trigonometric functions. Fourier analysis is named after a man who proved that representing a mathematical function in the form of a sum of a trigonometric function simplifies the inquiry into heat propagation. Joseph Fourier envisioned the Fourier series, a concept from which Fourier analysis grew. Presently, vast spectrums of mathematics involve Fourier analysis as a subject. The subject spans through the field of engineering and sciences. In these two fields, Fourier analysis involves the process through which a function is decomposed into simpler functions. The ...

Parkinson’s disease was first described by James Parkinson in 1817 as the “shaking palsy”. A person with Parkinson’s disease suffers from continuous shaking tremors while they are at rest, a phenomenon known as “pill rolling” (Jankovic, 2008). There are several public figures that live with Parkinson’s disease including the actor Michael J. Fox, the boxer Muhammad Ali, and former Attorney General Janet Reno. While tremendous research efforts have uncovered many important aspects of this disease, it is still unclear what determines the onset of this disease. The majority of Parkinson disease cases are idiopathic, meaning that there ...

The manifestation of cancer begins when the cells in the body multiply out of control. There are various kinds of cancer with each type starting with the out-of control rapid growth of cells. In most cases, the rapid multiplication of the abnormal cells leads to the growth of tumors. Tumors can either be benign or malignant. Benign tumors are neither cancerous nor life threatening due to the fact that they do not move to other body parts. Malignant tumors cause cancer and are capable of spreading to other body parts close to the tumor. Malignant tumors are capable of ...

Biomedical engineering is a discipline that encompasses engineering field and medical field in order to solve pertinent problems. It bridges the gap between medicine and engineering. The products of this endeavour include the design and development of therapeutic and diagnostic devices, prostheses, imaging equipment such as Magnetic Resonance Imaging (MRI) etc. The field of biomedical engineering thus has three main specialization areas which are (i) biomechanics, (ii) tissue and cellular engineering and (iii) imaging. These specialization areas are explained further in the following sections of this paper.
i. Biomechanics
Biomechanics is the study of mechanics in the human body ( ...

Impulsive Behavior Among Teenagers

Teenagers behave erratically when a massive transformation triggered by the sudden bout of hormonal changes takes place in their body and minds. They often contradict their actions. A teenager may secure top scores in school and be the best at whatever she or he does, but the same teenager might show a complete irresponsible behavior by taking things like not driving while drunk or not texting while driving casually and ends up in an accident. It often makes adults wonder how come teenagers who apparently seem to be responsible, smart and accomplished in their behavior could be so irresponsible and reckless ...

Multiple sclerosis (MS) is a chronic inflammatory disorder related to Central Nervous System; it affects brain and spinal cord. Primary MS symptoms include tingling, weakness, numbness, and hazy vision. While some other signs are linked to thinking problems, muscular stiffness, body balancing during walk and urinary problems.
Multiple sclerosis is manifested morphologically by inflammation and primary demyelination of neurons. The dispersed inflammatory lesions are distinguished by immense permeation of varied cellular mediators of the immune system that includes T and B cells, macrophages and microglia. ...

Introduction

The complex mysteries of the brain have been the subject of constant debate, intrigue and controversy for many years. Over the last few decades, the mysteries on the working of the brain have started to be more clearly understood. Neuropsychology is at the forefront of making this possible through technological advancements in imaging. Neuropsychology is the study of how the brain and its complex components impact on behavior (Hartlage, Lawrence and Long 3). Neuropsychology also comprises of studying how behavior is affected by brain function. In this science, the function of the brain is evaluated through objective testing of ...

Introduction

It has been known that all living things have electrical charges in their bodies. These electrical charges are distributed throughout the body of an organism. In the modern physiology, it has been found out that it is possible to measure the strength of charges in the body as well as their distribution. The human body is not exempted since it contains the electrical charges as well. In addition, a number of the modern equipment used in hospitals such electrocardiogram, electromyogram, nuclear magnetic resonance imaging and electroencephalogram all depend on the distribution of electrical charges in the body so as to ...
