Bio-psych: Localisation of function in the brain

Question 1

Define localisation

Answer 1

The theory that different areas of the brain are responsible for specific behaviours, processes and activities

Question 2

Define motor area

Answer 2

Region of frontal lobe

Involved in regulating movement

Question 3

Define somatosensory area

Answer 3

Area of parietal lobe

Processes sensory info (e.g touch)

Question 4

Define visual area

Answer 4

Part of occipital lobe

Receives/processes visual info

Question 5

Define Auditory area

Answer 5

Located in temporal lobe

Concerned with analysis of speech-based info

Question 6

define Broca’s area

Answer 6

Area of frontal lobe
left hemisphere

Question 7

what is the Broca’s area responsible for?

Answer 7

speech production

Question 8

Define Wernicke’s area

Answer 8

area in temporal lobe
left hemisphere

Question 9

what is Wernicke’s area responsible for?

Answer 9

language comprehension

Question 10

A03 of localisation (Evidence for brain scans)

Answer 10

strength

Petersen (et al)- used brain scans to demonstrate activity = Wernicke’s area = listening tasks , Broca’s area = reading tasks

long-term memory studies by petersen et al- episodic & semantic memories = found in different parts of prefrontal cortex

Question 11

A03 of localisation (counterpoint of evidence for brain scans)

Answer 11

limitation
Lashley removed 10-50% of rat’s cortex , learned to navigate a maze
