Historical Antecedents of Apparent Cerebral Dominance 1836 : French physician, Marc Dax, reported on language deficits observed only in those presenting with damage to left side of the brain Report had little impact since localization of function theories were not popular at the time 1864 : Paul Broca reported that post mortem examination of 7 aphasic patients showed damage in the inferior prefrontal ctx of the left hemisphere Early 1900’s : observations were made that apraxia typically occurred in response to left hemisphere damage

Neurological Patients Sustaining damage to homotypic regions of different hemispheres produces unique behavioral deficits Clinical cases of damage to this region Show difficulties in copying drawings, assembling puzzles, navigating streets in a familiar city Right hemisphere Injury causes impairment in language, copying movements, reading, and generating names for familiar objects and animals Left hemisphere
