1

What is the forebrain composed of?

Diencephalon
Cerebral hemispheres

2

What features are associated with the diencephalon?

Adaptability
Flexibility
Creativity

3

What is cognition?

Interrelated conscious or unconscious mental activities
Includes memory, visuospatial processing, executive processing

4

What are the functional areas of the frontal lobe?

Primary motor cortex
Premotor cortex
Prefrontal cortex

5

What function is associated with the primary motor cortex?

Gross and fine motor movement

6

What function is associated with the premotor cortex?

Planning and selecting movement

7

What function is associated with the prefrontal cortex?

Integration of sensory info

8

What are the signs of damage to the frontal lobe?

Problems thinking complexly, concentration, executive functions, sequencing and speed
Personality changes
Broca's aphasia

9

What personality changes are associated with damage to the frontal lobe?

More placid
Disinhibited
Emotional instability
Social difficulty

10

What are executive functions?

Processes that underlie flexible goal-directed behaviour
Ability to achieve insight and awareness

11

What are examples of executive functions?

Shift from one concept to another
Modify behaviour in light of new info
Piece info together
Manage multiple sources of info
Make use of relevant acquired knowledge

12

What test is used to assess executive function?

Wisconsin card sorting test

13

What are the functions of the parietal lobe?

Visuospatial location
Language
Attention
Learning of tasks requiring coordination of body in space

14

What are the functional parts of the parietal lobe?

Primary somatosensory cortex
Somatosensory unimodal association area
Multimodal sensory association area

15

What function is associated with the primary somatosensory cortex?

Receives sensory info

16

What function is associated with the somatosensory unimodal association area?

Further processing of sensory info

17

What function is associated with the multimodal sensory association area?

Integrates visual, auditory and movement stimuli

18

What are the results of damage to the parietal lobe?

Neglect 1/2 field of vision
Apraxia
Agnosia
Difficulty integrating sensory information from various parts of the body
Difficulty with numbers in relation to one another
Difficulty manipulating objects

19

How is damage to the parietal lobe assessed in rats?

Water maze

20

What is apraxia?

Inability to carry out a movement

21

What is agnosia?

Inability to recognise words, numbers or objects

22

What are the functional areas of the occipital lobe?

Primary visual cortex
Visual unimodal association area

23

What function is associated with the primary visual cortex?

Process information from the thalamus

24

What function is associated with the visual unimodal association area?

Processing information from the primary visual cortex

25

What are the results of damage to the occipital lobe?

Anton syndrome
Optic ataxia
Inability to recognise what is seen

26

What is Anton Syndrome?

Loss of vision in a normal appearing eye
Stimuli are received but not processed
'Denial' of vision loss; brain makes up stimuli

27

How is damage to the occipital lobe assessed?

Unable to recognise and recreate a drawing

28

What information is processed in the temporal lobe?

Auditory, gustatory, visceral and olfactory
Facial recognition

29

What are the functional areas of the temporal lobe?

Primary auditory cortex
Auditory unimodal association area
Visual unimodal association area
Multimodal sensory association area
Limbic association area
Amygdala and hippocampus

30

What are the functions of the amygdala?

Initial interpretation of sensory stimulus based on memory of past events
Fear and aggression
