Localisation Of Function In The Brain And Hemispheric Lateralisation

Question 1

What two theories are opposing?

Answer 1

Localisation of function
Hemispheric lateralisation

Question 2

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

Answer 2

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

Question 3

Hemispheric lateralisation suggests the brain is split into two…

Answer 3

Symmetrical halves called the left and right hemisphere

Question 4

In hemispheric lateralisation, the two different hemispheres are responsible for different…

Answer 4

Processes e.g. left hemisphere is responsible for language and the right is responsible for recognition and creativity

Question 5

The holistic theory occurred before investigations into…

Answer 5

Localisation and lateralisation

Question 6

Holistic theory suggested that all parts of the brain…

Question 8

Brocade’s area is in which hemisphere?

Answer 8

Left

Question 9

What is Broca’s area involved in the production of?

Answer 9

Spoken and written language

Damage to the Broca’s area can produce…

Answer 10

Broca’s aphasia

Question 11

Broca’s aphasia is when a person may show…

Question 14

Each hemisphere controls the movement of which side of the body?

Answer 14

The opposite side

Question 15

Damage to the motor cortex can cause loss of what?

Where is the somatosensory cortex found?

Answer 16

Both hemispheres

Question 17

What does the somatosensory correct process?

Damage to the somatosensory cortex can produce problems in perceiving…

Answer 18

Touch, failure to recognise object by touch

The visual cortex receives information directly from…

Answer 20

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

Question 21

The visual cortex processes information such as…

Answer 21

Colour and shape

Question 22

If the visual cortex becomes damaged it can produce…
