I found this article through pub med. It talks about the syntactic abilities of someone with aphasia and the research they found after computing tests on patients with aphasia. The experiment consisted of twelve control patients and twelve aphasia patients. Three different areas were covered and tested. These included spontaneous speech, picture description with preparation and help, and picture description without help. The results showed that Brocas patients were most successful when prepared for the task and that they worked off short term memorization instead of actual knowledge.
