1
Q

What was the view of the holistic theory?

A

That all parts of the brain were involved in processing thought and action

2
Q

What was later found out about localisation theory?

A

Specific areas of the brain were later linked with specific physical and psychological functions

3
Q

What was discovered about a part of a brain being damaged?

A

If an area of the brain is damaged through illness or injury, the function associated with that area is also affected

4
Q

What is the brain divided into?

A

The left and right hemispheres

5
Q

What is lateralisation?

A

Some physical and psychological functions are controlled by a particular hemisphere

6
Q

Which hemisphere controls which side of the body?

A

Generally, the last side of the body is controlled by the right hemisphere and vice versa

7
Q

What is the outer layer of the brain called?

A

The cerebral cortex

8
Q

What separates humans from other animals?

A

The cerebral cortex is about 3mm thick and is highly developed

9
Q

How many lobes are located in the cortex?

A

4

10
Q

What are the lobes located in the cortex?

A

Frontal, parietal, occipital, temporal

11
Q

Where is the motor area located?

A

At the back of the frontal lobe (both hemispheres)

12
Q

What does the motor area do and what might damage cause?

A

Controls voluntary movement, may result in loss of control over fine motor movements

13
Q

Where is the somatosensory area located?

A

At the front of the parietal lobes

14
Q

What does the somatosensory area do?

A

Processes sensory information from the skin

15
Q

Where is the visual area located?

A

In the occipital lobe at the back of the brain

16
Q

What does the visual area do and what might damage cause?

A

Eye sends information from right visual field to left visual cortex and vice versa - damage to left hemisphere could produce blindness in right visual field or both eyes

17
Q

Where is the auditory area located?

A

In the temporal lobe

18
Q

What does the auditory area do and what might damage cause?

A

Analyses speech based information - May produce partial hearing loss depending on severity of injury

19
Q

Where is Broca’s area?

A

Left frontal lobe

20
Q

What is Broca’s area responsible for?

A

Speech production

21
Q

What can damage to Broca’s area cause?

A

Broca’s aphasia - characterised by speech that is slow and lacking in fluency, may have difficulty finding words for naming objects

22
Q

Where is Wernicke’s area?

A

The back of the temporal lobe

23
Q

What is Wernicke’s area responsible for?

A

Language comprehension

24
Q

What can damage to Wernicke’s area cause?

A

Patients produce language but have problems understanding it, they produce fluent meaningless speech

25
Q

What do patients with Wernicke’s aphasia produce?

A

Nonsense words as part of their speech
