Paul Broca’s Case study 1861 Scottie, Eli, Jay, Brad
Introduction • Paul Broca was a French surgeon who studied two brains after they had gone through injury to the posterior inferior frontal gyrus of the brain. • Broca found that people suffering from damage in the left frontal lobe of the brain were unable to understand and make grammatically complex sentences.
Leborgne (Tan) • Leborgne had multiple neurological problems • He had been without productive speech for multiple years. • When trying to communicate in any situation he was only able to mutter a single syllable response, “tan”. • Because he had no productive language, Broca questioned the language localization in the frontal lobes.
Death of Leborgne • After he died, an autopsy was performed on Leborgne’s brain and this is where Broca discovered a lesion on the left frontal lobe. • This finding was very instrumental in providing support that cognitive functions could be localized to specific areas of the brain.
Second Patient: Lelong • Lelong suffered from reduced levels of speech due to a suffering a severe stroke a year before. • Because of a lesion on his lateral front lobe, he could only mutter five words that consisted of… • No • Yes • Three • Always • Lelo (a mispronunciation of his own name)
Broca’s Credit • Broca’s documentation of these patients became essential to making an important connection between language and the inferior frontal gyrus of the left cerebral hemisphere. • After Broca passed, the region he identified has become known as Broca’s area. • The lack of language production is now known as Broca’s aphasia.
