The Moral Lobe: The Importance And Functions Of The Brain.
Brains scans are used to view the brain without actually having cranial surgery. They combine camera images with a computer to give a view of what is going on inside someone's or something's head. Some scans are used to delineate the structure of a disease, other scans are used to find brain injuries or tumors, and still others are used to study how the brain works. There are seven main scans.
The difference between the two scans shows which part of the brain is being used.. Discuss the use of brain imaging technologies (for example, CAT, PET, fMRI) in investigating the relationship between biological factors and behaviour (22) You will need to plan an essay which will be about 2-3 sides of A4 long, including a detailed focus on the command term. The marking criteria are below.
Sample Essay (993 Words). brain matter and is used to investigate tumours or any possible brain damage. However, MRI scans are limited to only showing structural changes and need careful interpretation to prevent false positives. Therefore, researchers need to be cautious when interpreting the data from MRI scan to examine the relationship between brain and behaviour, to ensure that their.
Beyond doubt MRI is the choice of modality in imaging spine and brain as, due to very high contrast resolution, MRI provides excellent white and grey matter differentiation. This has made complicated operations of the brain and spine simpler. Apart from the imaging of brain and spine, MRI has also been successfully used in the region of abdomen.
On his desk, among the brain scans of murderers, depressives and schizophrenics, were scans of him and his family, part of a separate study being done on Alzheimer's disease.
MRI is a much more detailed scan compared to for example, CT scans, as they provide clearer images of the brain which makes it easier for neuroscientists to identify any abnormalities in brain structure. Furthermore, the technique has relatively high spatial resolution and it can produce images in three dimensions which can give a more advanced view into the brain (Martin, 2005). Moreover, MRI.
Firstly, the scans are not a natural environment for cognition, so there is a question of ecological validity. Secondly, the use of colors may be exaggerated. Also, brain areas might activate for various reasons, thus, one cannot be sure that a certain cognitive activity was related to a change in the brain. Finally, all the above mentioned techniques use radioactivity, which raises a question.
