Mapping brain function

To further understand the different lobes of the cerebral cortex as well as the various neuroimaging techniques such as the fMRI that are available for mapping and exploring brain function, consider the following two case studies:

1. Over the last few weeks, Mr. Roberts has been bothered by nausea, frequent fainting spells, and severe headaches. Describe at least two different ways such as neuroimaging techniques for example, which a physician might seek to determine whether Mr. Roberts' symptoms are a result of brain injury or disorder. Include a rationale for the choice of techniques.

2. After a mild stroke, Mrs. Smith has been showing signs of aphasia. What pattern of symptoms would lead you to believe the damage occurred primarily in (a) Wernicke's area (b) Broca's area?

Hello -

I have attached a summary of some main points to address the questions above. Though I included references, this information is readily available in most psychology textbooks, so you can probably refer to your text for specific definitions.

Hope this helps!

Include a rationale for the choice of techniques.

The best imaging techniques would be those that could identify brain trauma (possibly from swelling or concussion), or compromised blood flow, which would cause brain dysfunction.

The most useful technique would probably be a CT (Computed Axial Tomography) scan. This method compiles X-rays taken from different angles. The X-rays are ...
