lobes of the brain (chapter 4)

Question 1

what are the 4 distinct regions of the brain?

Answer 1

the frontal lobe, parietal lobe, temporal lobe and the occipital lobe

Question 2

what are the frontal lobe’s 4 areas

Answer 2

• pre-frontal cortex
• primary motor cortex
• pre motor cortex
• broca’s area

Question 3

what is the pre-frontal cortex

Answer 3

the pre-frontal cortex is a part of the frontal lobe, and is the association area.

it is responsible for:
- planning
- reasoning
- judging
- initiative
- problem solving
- personality
- attention
- control of emotions

Question 4

primary motor cortex

Answer 4

• initiates and controls voluntary movement of skeletal muscles
• contralateral functioning
• upside-down representation

(frontal lobe)

Question 5

pre motor cortex

Answer 5

• voluntary motor movement
• sends sequence of movements to PMC

(frontal lobe)

Question 6

broca’s area

Answer 6

production of articulate speech that is clear and fluent (in the left hemisphere) via the muscles that control the mouth

(frontal lobe)

Question 7

what are the areas in the parietal lobe

Answer 7

• primary somatosensory cortex
• association area

Question 8

primary somatosensory cortex

Answer 8

• responsible for processing sensation of touch, pressure, temperature and pain
• contralateral functioning
• upside-down representation

(parietal lobe)

Question 9

association area (parietal lobe)

Answer 9

• location of body in space
• location of objects around them
• perception of 3D shapes and designs

Question 10

what are the 2 areas in the occipital lobe

Answer 10

• primary visual cortex
• association area

Question 11

primary visual cortex

Answer 11

• receives visual input from each retina
• registers and processes different visual stimuli

(occipital lobe)

Question 12

association area (occipital lobe)

Answer 12

• organisation of visual stimuli
• interpretation, identifying objects
• interaction with other lobes to integrate visual info with memory, language and sounds

Question 13

what are the areas in the temporal lobe

Answer 13

• primary auditory cortex
• association area
• Wernicke’s area

Question 14

primary auditory cortex

Answer 14

registers and processes auditory info from speech, music or non-verbal sounds (pitch and loudness)

Question 15

association area (temporal lobe)

Answer 15

• associated with hearing, understanding speech and interpreting sounds
• plays an important role in forming memories
• facial recognition performed in right temporal lobe
