one of the first indications of brain function lateralization resulted from the research of french physician pierre paul broca, in 1861. his research involved the male patient nicknamed "tan", who suffered a speech deficit (aphasia); "tan" was one of the few words he could articulate, hence his nickname. in tan's autopsy, broca determined he had a syphilitic lesion in the left cerebral hemisphere. this left frontal lobe brain area (broca's area) is an important speech production region. the motor aspects of speech production deficits caused by damage to broca's area are known as expressive aphasia. in clinical assessment of this aphasia, it is noted that the patient cannot clearly articulate the language being employed.
