Localisation of function in the brain Flashcards
1
Q
What did Broca and Wernicke discover
A
- that particular areas of the brain are associated with particular physical and psychological functions, in short they argued for localisation of function, the idea that different parts of the brain perform different tasks
2
Q
In short what did Broca and Wernicke argue
A
- in short they argued for localisation of function, the idea that different parts of the brain perform different tasks
3
Q
What is the term used to describe when some of our physical and psychological functions are controlled or dominated by a particular hemisphere
A
- lateralisation
4
Q
What is the outer layer of both hemispheres
A
- the cerebral cortex
5
Q
How thick is the cerebral cortex
A
- 3mm thicc
6
Q
Why does the cortex appear grey
A
- due to the location of cell bodies
7
Q
What is at the back of the frontal lobe
A
- the motor area which controls voluntary movement
8
Q
What is at the front of both parietal lobes
A
- the somatosensory area
9
Q
Where is the visual area located
A
- at the back of the brain
10
Q
Where is the auditory area located
A
- in the temporal lobes
11
Q
What did Broca identify
A
- small area in the left frontal lobe responsible for speech production
12
Q
What does damage to Broca’s area cause
A
- Broca’s aphasia which is characterised by speech that is slow, laborious and lacking in fluency
13
Q
What was Wernicke describing patients as
A
- no problem producing language but severe difficulties understanding it
14
Q
What did Wernicke identify
A
- a region in the left temporal lobe responsible for language comprehension
15
Q
What would damage to the Wernicke’s area result in
A
- Wernickes aphasia
