Summary
This document discusses the localization of language within the left hemisphere of the brain, focusing on Broca's area and the impact of lesions in this area on language abilities. It describes Broca's aphasia, noting its characteristics and the implications for speech and language structure. The document also includes a recap emphasizing the role of the frontal lobe in language processing and the distinction between impaired syntax and unimpaired semantics.

Localization within the LH: Tan’s Brain • 1861: Paul Broca examined Tan’s Brain (post-mortem). • Came to the conclusion that the loss of language ability was linked to the local damage in “Broca’s area”. Paul Broca 23 Localization within the LH: Tan’s Brain Broca examined more and more brains, and found: • • • Same language deficit, Same area damaged, Always left-hemisphere. 24 Broca’s Aphasia • Speech is broken and halted (telegraphic speech). • Words make sense, but the structure is incorrect. • Sometimes this type of aphasia is referred to as agrammatic aphasia. 25 Broca’s Aphasia 26 Recap • Broca’s Aphasia • Lesions found in particular part of the LH (frontal lobe) • Semantics (meaning): unimpaired • Syntax (structure): impaired 27
