Flashcards in 11.1 - Cortical Association Areas Deck (22):
1

What is the frontal lobe responsible for?

Higher intellect, personality, mood, social conduct, language (dominant hemisphere)

2

What is the parietal lobe responsible for?

Language, calculation (dominant hemisphere), visiospatial functions (non dominant hemisphere)

3

What is the temporal lobe responsible for?

Memory and language

4

What is the occipital lobe responsible for?

Vision

5

What would occur in damage to the temporal lobe?

recognition deficits e.g. agnosia and prosopagnosia

6

What would occur in damage to the temporal lobe?

attention deficits

7

What is the funciton of the limbic system?

rewards appropriate behaviours and punishes inappropriate behaviours

8

Which side is usually dominant in the brain? WHat does the dominant hemisphere do?

Normally left Language, maths, logic, motor skils

9

What does the non dominant hemisphre do?

emotion, music/arts, visiospatial, body awareness

10

Where is the input for language found in the brain

Wernickes area

11

Where is the output for language found in the brain?

Brocas area

12

What is the pathway for speaking a heard word?

Primary auditory area --> wernickes area --> Broca area --> motor cortex

13

What is the pathway for speaking a written word?

Primary visual area --> wernickes area --> Brocas area --> motor cortex

14

What happens if the wernickes area is damaged?

Wernickes aphasia. Disorder of comprehension, fluent but unintelligible speech. Less severe if non dominant side is damaged

15

What happens if the Brocas area is damaged?

brocas aphasia. Poorly constructed sentences and disjointed, but normal comprehension.

16

What is conduction aphasia?

difficulty in repition

17

What are the 2 types of memory?

Declarative - naming objects and places. Further subdivided into long and short term. Procedural - Motor memory

18

How are memories committed to long term?

emotion involved, repitition, association, automatic memory

19

Describe how a memory is made, and stored

Cortical sensory areas --> amygdala and hippocampus where memory occurs --> diencephalon, basal forebrain, prefrontal cortex where it is organised for storage

20

How are memories formed and forgotten?

LTP and LTD

21

What are the 2 types of amnesia?

Anterograde (cannot form new memories) retrograde (cannot remember previous memories)
