You are basically correct. In theory, if you lesion an area for taste, you should stop being able to taste stuff. A lot of the lesions you mentioned produce agnosias of one kind or another, but taste is an exception. Damages to gustation are - geusias. So to have a loss of taste, you stick on the prefix a- and get ageusia. I say that you are basically correct because as you probably know, the brain is infinitely more complicated than that. Many cognitive processes have degenerate systems so that if one is damaged, another can take over and make up the difference. For the purposes of your class, however, it sounds like your instructor just wants you to assume that damage to the region in question will cause a loss of function. If you have more specific questions post back. I would be happy to help as much as possible (without doing your homework for you!) Also, this is one case in science in which spelling counts: you will probably have a lot more luck if you search for Brodmann areas rather than Broadmann.
