Q

Localisation of function suggests that specific areas of the brain are…

A

Specialised for certain functions. E.g motor cortex is responsible for voluntary movement only this area is responsible for this job

Q

Broca’s aphasia is when a person may show…

A

Slow speech that lacks fluency or a complete absence of speech. They may produce short meaningful speech that requires a great deal of effort

Q

Damage to the motor cortex can cause loss of what?

Q

Where is the somatosensory cortex found?

A

Both hemispheres

17
Q

What does the somatosensory correct process?

A

Information from the senses in the skin including touch, pressure, pain and temperature from all areas in the body

18
Q

Damage to the somatosensory cortex can produce problems in perceiving…

A

Touch, failure to recognise object by touch

19
Q

Where is the visual cortex found?

A

Both hemispheres

20
Q

The visual cortex receives information directly from…

A

The eyes. Right visual field in left hemisphere, left visual field in right hemisphere

21
Q

The visual cortex processes information such as…

A

Colour and shape

22
Q

If the visual cortex becomes damaged it can produce…

A

Blindness, hallucinations or inability to see colour or motion

23
Q

Wernicke’s area is found in…

A

The left hemisphere

24
Q

Wernicke’s area is involved in…

A

The understanding of language

25
Damage to Wernicke’s area can cause…
Wernicke’s aphasia
26
What is Wernicke’s aphasia?
Individuals cannot understand spoken language of produces nonsense words as part of their speech. Fluent but meaningless speech
27
Where is the auditory cortex found?
Both hemispheres
28
What is the auditory cortex associated with analysing?
Speech based information e.g hearing pitch and volume
29
Damage to the auditory cortex can produce…
Partial hearing loss through to full hearing loss
30
In an essay what areas do you always need to talk about and compare?
Broca’s area and Wernicke’s area
