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 ex, 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?
