1. Brain lateralization - vision & sensory/motor systems - that why we learn pathways - language - we’ll learn here - Split Brains

13. Cerebral lateralization • Left Right • serial - parallel • language - faces/ patterns • - emotional stuff • - music • - spatial ability

17. Language in the Brain Learn about language? Lesion studies ‘Tan’ - famous patient Broca’s Aphasia - slow labored speech - not fluent - little/no language production - some sing/hum familiar tunes - use nouns & verbs (essential meaning) - no conjuctions, prepositions, pronouns ( grammar) The general commands the army. No ifs ands or buts.

19. Language in the Brain Broca’s Aphasia Agrammatism Anomia Articulation

23. Language in the Brain Wernicke’s Aphasia - receptive deficit Pure word deafness - fail to recognize word (?) recognize emotion, source Transcortical Sensory Aphasia - language loses meaning - can still repeat - damage - posterior language area Conduction Aphasia - good comprehension, production - poor repetition - damage - arcuate fasciculus

26. Language in the Brain Wernicke’s Aphasia - receptive deficit Pure word deafness - fail to recognize word (?) recognize emotion, source Transcortical Sensory Aphasia - language loses meaning - can still repeat - damage - posterior language area Conduction Aphasia - good comprehension, production - poor repetition - damage - arcuate fasciculus

39. Aphasia Area Speech Comp Repet Naming Wernicke’s STG fluent poor poor poor Broca’s frontal nonfluent good poor? good Conduction Arc. Fas. fluent good poor good Transcortical Posterior fluent poor good poor Sensory Language

40. This is really old!!!

41. Language in the Brain Anomia revisitied - temporal lobe damage - pole - proper nouns (people places things) - inferior temporal - common nouns (categories) Verbs - frontal - cerebellar

49. Pure Alexia

50. Language Development - receptive - productive - speech - written
