- 1Which hemisphere shows advantage in speech production and comprehension?Left hemisphere
- 2In what % of right handers speech is lateralised?95%
- 3In what % of left handers speech is lateralised?75%
- 4Which hemisphere has the advantage in terms of non speech verbal skills, e.g. singing, humour?Right hemisphere
- 5When is the Wada/ Sodium Amytal test used?Prior to surgery of temporal lobe epilepsy
- 6What is the Wada/ Sodium Amytal test?Sodium amytal is injected into one of the hemispheres in transient ipsilateral hemiparesis to look for speech impairment
- 7Why is fMRI and PET good method of imaging?Good spatial resolution
Have shown different areas for nouns vs words and concrete vs abstract - 8What does ERP measure?Brain activity during cognitive processing
Used to understand language processing - 9Why is ERP good?Good temporal resolution
- 10What is the procedure of putting a coil near scalp with powerful oscillating magnetic field?Transcranial Magnetic Stimulation
- 11What does TMS do?It generates or interrupts nerve impulses in desired brain region (can produce transient disruption in an area of key speech production)
- 12Define aphasiaPartial or complete loss of language skills resulting from an organic cause
- 13What % of stroke produce aphasia?40%
- 14How can you test for aphasia?Spontaneous speech production and tests for auditory comprehension and verbal recognition
- 15What is Broca's aphasia?Expressive non fluent aphasia
- 16In which type of aphasia is "telegraphic speech" found?Broca's aphasia
- 17What is anomia? Is it found in Broca's aphasiaYes, it's difficulty in finding words for object
- 18What is agrammatism?Problem processing complex grammer
- 19Where is Broca's area? What is it responsible for?Inferior frontal gyrus
Language production - 20What is Wernicke's aphasia?Receptive or fluent aphasia
- 21How is Wernicke's aphasia characterised?Fluent meaningless speech
- 22Are patients aware of their deficit?Often unaware of deficit- anosognosia
- 23What is semantic paraphrasias? Is it found in Wernicke's or Brocas?Wernicke's aphasia- say horse instead of cow
- 24What is meaningful, fluent speech, intact comprehension but poor non- word repetition?Conduction aphasia
- 25How can conduction aphasia arise?Damage to arcuate fasciculus between Wernicke's and Broca's area
- 26What is Transcortical Sensory Aphasia? How it occurs?Inability to comprehend meaning or produce meaningful speech spontaneously.
Arises due to damage in posterior language centers. - 27What disease is characterised by "formal thought disorder"?schizophrenia
- 28How can you recover from aphasia?Recruitment of right hemisphere
- 29Explain the Wernicke- Geschwind ModelWA- auditory codes for words and meanings
BA- articulatory codes for words- motor commands - 30Explain the Wernicke- Geschwind Model in terms of speaking1. Auditory activation of WA
2. Transmission from WA to BA
3. Articulatory codes activation in BA, sent to motor cortex - 31Explain the Wernicke- Geschwind Model in terms of comprehenssion1. Receive words in primary auditory cortex
2. Sends information to WA, where sound is matched to auditory code - 32What is whole- word reading based on?Visual appearance of familiar words
- 33What is phonetic reading?Uses sounds of letters, used for regular words and non work reading
- 34What is agraphia?Writing disorder
- 35Is reading and writing a dissociable skill?Yes
- 36Whole word route damaged, phonetic route sparedsurface dyslexia
- 37What is deep dyslexia?Phonetic route damaged, whole world route spread
- 38What is developmental dyslexia?Child or normal intelligence with difficulty learning to read
