1
Q

precentral gyrus

A

Motor cortex

2
Q

Post central gyrus

A

somatosensory cortex

3
Q

where is the auditory cortex?

A

Superior temporal gyrus

4
Q

Where is the visual cortex

A

Gyri of calcarine sulcus

5
Q

the cingulate gyri and parahippocampal gyrus join here

A

isthmus

6
Q

where is the olfactory cortex?

A

Uncus

7
Q

where is the collateral sulcus?

A

medial surface of the temporal lobe

8
Q

what is the other term for calcarine gyrus?

A

striate cortex

9
Q

where is the gustatory (taste) cortex located?

A

Inferior post central gyrus

10
Q

Where does the lateral ventropostral nucleus receive information from?

A

leg

11
Q

where does the medial ventropostral nucleus recieve information from?

A

arm

12
Q

where is the general sensory area located

A

superior parietal lobe

13
Q

what is the function of secondary areas?

A

they are the association areas that provide understanding to sensory input.

14
Q

what does equipotential mean /

A

the sensory and motor association areas function the same amount

15
Q

Agnosia

A

Agnosia is when awareness persists but there is no understanding of the sensation.
It occurs when the secondary sensory areas are damaged.

16
Q

What is Apraxia?

A

Apraxia is the inability to perform purpose movements. It is caused by damage to secondary motor areas.

17
Q

What is the general association cortex?

A

it has an integrative function. It links together all the senses and the hippocampus.

  • The parieto-temporal cortex is involved in memory.
  • The Prefrontal cortex is involved in regulating moods and feelings. It allows decisions to be made by analysing previous experiences.
18
Q

Language areas of the brain

A

2 language areas are in the Dominant hemisphere.

1) posterior area (wernicke’s area) is for understanding
2) Anterior area (Broca’s area) is for production of language.

19
Q

what is aphasia?

A

damage to wernicke’s area causes inability to understand language.
damage to broca’s area causes inability to articulate speech.
