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

13. Cerebral lateralization LeftRight -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.

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

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

51. Language in the Brain Reading 2 types - phonological (phonetic) - sound it out - learning phase - slow - graphemic ( whole word, lexical) - recognize word, irregular word - Chi Chi Rodriguez - epinephrine - fast, error prone if proofreading

52. Language in the Brain Dyslexia - lots of different types Developmental - won’t cover Aquired dyslexias Surface dyslexia - no whole-word reading Phonological dyslexia - can not sound out Word-form dyslexia (letter-by-letter) Direct dyslexia (deep dyslexia)
