Methods of studying cortical specialisation are divided into two groups: the invasive‚ and the non-invasive. The invasive methods are those‚ in which something is injected into the brain‚ to find out what the problem is. The non-invasive methods are more ethical‚ as there are no changes in the brain area‚ therefore no damage can be done to it. One of the invasive methods of cortical specialisation is neurosurgery. It involves manipulating with the structures within the brain. There are two main

The Importance of Physics to Society Physics - the study of matter‚ energy and their interactions - is an international enterprise‚ which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: 1. Physics is an exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about Nature. 2. Physics generates fundamental knowledge needed for the future technological advances

Recent advances in technology permit measurement of characteristics of the nerve fibres that make up the optic nerve. One of these is SD-OCT(Fig2)‚ a non contact‚ non-invasive method that enables physicians to obtain in vivo‚ high resolution (upto 5 microns) cross-sectional images of the retina. It is based on principle of low-coherence interferometry(Fig 3). By imaging a 3D cube of data it allows a detailed evaluation of the peripapillary area.

Magnetic resonance imaging (MRI) is a type of scanner that uses strong magnetic field and radio waves to produce complete images inside the body. An MRI scanner is a large tube that contains strong magnets. The patient lie inside the tube during the scan. The MRI scanner is used to observe almost any part of the body including the brain and spinal cord‚ bones and joints‚ breasts‚ heart and blood vessels and internal organs such as the liver‚ womb or prostate gland. The results of an MRI scan can

Radiologic Technologist Education/Training Required: To become a radiologic technologist you must obtain a certificate‚ an associate’s degree‚ or a bachelor’s degree. To obtain this‚ there are formal training programs in radiography that one can join. Most radiologic technologists obtain their associate’s degree. The typical coursework of a radiologic technologist includes anatomy‚ pathology‚ patient care‚ radiation physics and protection‚ and imaging evaluation. Hospitals‚ which employ most

MRI (Magnetic Resonance Imaging) and CAT scans are used by doctors daily. However there are some differences such as CAT scans uses radiation meanwhile MRI doesn’t. Another difference is that MRI is a closed tube meanwhile CAT scan isn’t closed and has lots of space. Both MRI and CAT scans have pros and cons. A CAT scan is an x-ray image made by using radiation and MRI is the use of magnetic field and radio waves to create images of our body. One pro for CAT scans is that it detects diseases before

Veterinary Technician A Veterinary Technician works as a skilled technical assistant to a veterinarian‚ or to another biomedical researcher or scientist. Veterinary technicians do not prescribe‚ diagnose‚ or perform surgery‚ and they always work under the supervision of a veterinarian. Thus being said‚ a veterinary technician career is a natural step for an aspiring veterinarian wanting to test the waters. Most veterinary technicians find employment in private veterinary practices doing traditional

The decision to perform CT/CBCT imaging depends on both the initial radiographic valuation and the clinical findings. If the plain radiographs are negative‚ with no signs of fracture‚ no fluid levels‚ no mucosal thickening of the sinuses‚ and no orbital or soft tissue emphysema and there is no indication of penetrating injury‚ then the chance of finding a significant midface fracture on CT/CBCT evaluation. There are very high incidence of intracranial damage in such patients‚ and there are important

PS1030 Essay – Psychology – Rachelle Petho Describe three brain-imaging techniques and explain what the literature tells us about the function and structure of the brain. This essay is going to describe three different types of brain-imaging techniques. It will also explain what the literature tells us about the function and the structure of the brain. The three types of brain-imaging techniques that will be clearly described are; CT (computed tomography)‚ PET (Positron Emission Tomography) and MRI

Describe and evaluate methods of investigating cortical specialisation. (10 marks) There are many different methods of cortical specialisation and these are: MRI scan‚ PET scan‚ Electroencephalogram‚ Post Mortem and Neurosurgery. These are developed methods of studying cortical specialisation in the brain in order to be able to predict‚ control and explain non –human and human behaviour. Neurosurgery is considered to be an invasive way of investigating cortical specialisation as it involves manipulating
