Editing Broca's area (section)

===MRI findings===

Examination of the brains of Broca's two historic patients with high-resolution [[MRI]] has produced several interesting findings. First, the MRI findings suggest that other areas besides Broca's area may also have contributed to the patients' reduced productive speech. This finding is significant because it has been found that, though [[lesions]] to Broca's area alone can possibly cause temporary speech disruption, they do not result in severe speech arrest. Therefore, there is a possibility that the [[aphasia]] denoted by Broca as an absence of productive speech also could have been influenced by the lesions in the other region.{{Citation needed|date=August 2015}} Another finding is that the region, which was once considered to be critical for speech by Broca, is not precisely the same region as what is now known as Broca's area. This study provides further evidence to support the claim that language and cognition are far more complicated than once thought and involve various networks of brain regions.<ref>{{Cite web|url=http://memory.ucsf.edu/brain/language/anatomy|title=Anatomy of Speech & Language {{!}} UCSF Memory and Aging Center|website=memory.ucsf.edu|language=en|access-date=2017-05-03|url-status=live|archive-url=https://web.archive.org/web/20170503173358/http://memory.ucsf.edu/brain/language/anatomy|archive-date=2017-05-03}}</ref>
