Ling 111-Exam 2, 4, Language And Brain

Front 1

What connects the hemispheres of the brain

Back 1

corpus callosum.

Front 2

Language is mostly in the ______ hemisphere

Back 2

left

Front 3

Auditory cortex

Back 3

• Receive auditory stimuli, convert into form interpretable by the rest of brain.
• One in each hemisphere.

Front 4

Visual cortex

Back 4

• Receives visual stimuli, convert into form interpretable by rest of brain.
• Storage of visual images, including things like letters, aspects of spelling.
• One in each hemisphere.

Front 5

Motor cortex

Back 5

Controls voluntary movement.

Front 6

3 regions that are not dedicated to language, but involved

Back 6

Auditory cortex, visual cortex, motor cortex

Front 7

4 Regions dedicated to language exclusively

Back 7

Broca's area, Wernicke's area, arcuate fasciculus, angular gyrus

Front 8

Broca's area

Back 8

• Organizing articulatory patterns – communicate these to motor cortex.
• Controls

Front 9

Wernicke's area

Back 9

• Mental lexicon = storage of content words (verbs, nouns, adjectives)
• Meaning = comprehension of language

Front 10

Arcuate fasciculus

Back 10

• Nerve fibers that connect Wernicke

Front 11

Angular gyrus

Back 11

• Converts visual stimuli into
linguistic stimuli.
• Used in reading.
• But also in recognizing a picture
and finding the word that would
name it.

Front 12

4 areas involvement in speaking a word

Back 12

• Wernicke: Think of concept, activate Wernicke

Front 13

3 areas involvement in reading a word

Back 13

• Visual cortex: Processes info perceived by eyes, identifies it as language, and transmits to
angular gyrus.
• Angular gyrus: Receives info from visual cortex, translates visual stimulus into linguistic
form, transmits linguistic info to Wernicke

Front 14

5 areas that deal with hearing a word and reading it out loud

Back 14

• Auditory cortex: Processes info perceived by ears, identifies it as language, and transmits
to Wernicke

Front 15

Computerized Axial Tomography (CAT scan)

Back 15

• Basically X-ray that can see soft tissue
• Converted to 3D with help of software

Front 16

Electroencephalograph (EEG)

Back 16

• Electrodes placed on scalp
• Measure electrical activity in different parts
of brain

Front 17

Magnetic Resonance Imaging (MRI)

Back 17

• Not X-ray – less dangerous
• Higher quality images = especially of
soft tissue.

Front 18

Remember to memorize picture of brain!!

Back 18

Remember to memorize picture of brain!!
