Answer 3

two hemispheres

Question 4

what are the 2 hemispheres connected by

Answer 4

the corpus callosum

Question 5

what does the mortor cortex do?

Answer 5

controls voluntary movement

Question 6

what does brocas area do?

Answer 6

responsible for production of speech

Question 7

what does the auditory cortex do?

Answer 7

processes information from our ears

Question 8

what does Wernicke’s area do?

Answer 8

responsible for the understanding of language

Question 9

Answer 9

processes information from our eyes

Question 10

what does the somatosensory cortex do?

Answer 10

processes information about touch, pain etc

Question 11

Answer 11

Region in the frontal lobe involved in regulating movement in

Question 12

Somatosensory area

Answer 12

Processes sensory information

Question 13

Visual area

Answer 13

Receives and processes information

Question 14

Auditory area

Answer 14

Speech based info

Question 15

Broca’s area

Answer 15

Produces speech

Question 16

Wernickes area

Answer 16

Responsible for language

Question 17

Peterson et al

Answer 17

Used brain scans to demonstrate how W area was active during listening task and B area was active during reading task suggesting these areas have different functions

Question 18

Who’s supports the theory of localised function?

Answer 18

PhineAse gage

Question 19

Who studies the effects of split brainsurgety?

Answer 19

Sperry 1968

Question 20

What was the method of sperry study?

Answer 20

11rps had undergone split brain as a result of epilepsy
In one of experiments rps covered one eye and looked at fixed points on a projection screen.
Pictures were projected onto right or left at high speeds so there was as no time for eye movements

Question 21

What were the results of sperry study?

Answer 21

Right=  say or write without a problem 
Left= couldn't write or say what they had seen

Question 22

What was the conclusion to the sperry study?

Answer 22

Shows different areas of the brain specialise different functions

Question 23

What was the evaluation of the sperry study?

Answer 23

Using case studies meant sperry obtained both qualitative and quantitive data
Small sample
Valid and reliable
Would have been difficult to find a lot of split brain patients to study
Hard to conclude it would be same as non epileptic patients
