Localisation of brain

Question 1

Localisation

Answer 1

Theory that specific areas of brain are associated with particular physical + psychological functions

Question 2

Hemisphere:

Answer 2

Divided into two hemispheres

Lateralisation: Physical + psychological functions controlled by specific hemisphere

Left side controlled by right hemisphere
right side controlled by left hemisphere

Question 3

Frontal lobe:

Answer 3

Left side (H) is Brocas area - Speech production
Damage = Slow and laborious speech, difficulty naming objects
Back is motor area (voluntary movements)
Damage = control over movements

Question 4

Parietal lobe:

Answer 4

Front is Somatosensory - information from skin

Question 5

Occipital lobe:

Answer 5

Visual area - sends information from rights visual field to left visual cortex
Damage + left produce blindness of right visual field - BOTH EYES

Question 6

Temporal lobe:

Answer 6

Auditory area - analyse speech-based information
Damage = hearing loss
Wernicke area - responsible for language comprehension
Damage = Wernickes aphasia - nonsense speech, meaningless

Question 7

AO3

Answer 7

Brain scan evidence:
Shows activity in Wernicke’s area during listening task
Brocas in reading task
Different functions

44 OCD patients - part of brain tissue removed
1/3 has shown successful response
Shows behaviours of serious mental disorders are localised

Phineas Gage - pole through frontal lobe
affected personality
Suggested frontal lobe = regulates mood

Higher cognitive functions - holistic
Removed areas of cortex that were learning a maze
Learning appeared to require every part of cortex
