1
Q

What line divides the frontal and parietal lobes?

A

The central sulcus

2
Q

Anterior to central sulcus? What is ti used for?

A

Precentral gyrus and paracentral lobule - Area 4 Used for precise control

3
Q

What is the premotor area for? Where is it?

A

Motor programming or indirect motor movement control

located anterior to primary motor cortex

4
Q

What special field is located at the caudal end of the middle and superior frontal gyri?

A

Frontal eye fields

Used for voluntary eye movements

5
Q

The supplementary motor area controls what?

A

Motor movement initiation and planning

Cortical micturation control center

6
Q

The pre-frontal cortex is used for what?

A

attention, motivation, planning, problem solving, judgment, social skills, emotional behavior, personality, working memory (short term)

7
Q

Where is Broca’s area?

A

Areas 44 and 45

The left inferior frontal gyrus

8
Q

What do you lose if you have a problem with the right inferior frontal gyrus?

A

You lose your prosody of speech.

You can’t express your emotions in language

9
Q

Where is your primary somatosensory cortex located?

Function?

A

POstcentral gyrus and posterior paracentral lobule (areas 3,1,2)

Fucntion: localiation of touch

10
Q

Where is the somatosensory association cortex?

What’s it for?

A

Superior parietal lobule, precuneus

Use it for identifying objects with touch without seeing them

11
Q

What is the multimodal association cortex for?

Where is it?

A

Integration of sensory information

Inferior parietal lobule

12
Q

What do you use the left posterior parietal lobule for?

the right?

A

Left: analytical skills

Right: visuospatial orientation

13
Q

What is the function of the calcarine cortex?

A

thats the location of the Primary Visual Cortex

(area 17, the lingual gyrus and part of cuneus)

14
Q

Location of visual association cortex (for color, motion, depth) ?

A

Lateral, medial, and inferior occiptial gyri

15
Q

Where do you find the involuntary cortical eye fields?

(for scanning eye movements)

A

Lateral occipital gyri

16
Q

Where do you fidn the primary auditory cortex?

(for hearing)

A

Areas 41 and 42

The Trasnverse temporal gyri

17
Q

What do you call the area surrounding the primary auditory cortex?

What’s it for?

A

Thats the auditory association cortex

Wernicke’s area in the superior temporal gyrus!

For language comprehension!!!!!!!!!!!

18
Q

Where is short-term memory incorporated into long-term memory?

A

The hippocampal formation

(within the temporal lobe)

19
Q

Limbic lobe parts:

A

Septum

Cingulate gyrus

Isthmus of cngulate gyrus

parahippocmapl gyrus

hippocampus

20
Q

What are the anterior and posterior parts of the limbic lobe for?

A

Anterior: emotional behavior and homeostasis

Posterior: Leranign and memory

21
Q

Where is the lcoation of the primary olfacotry cortex?

A

Rostral parahippocampal gyrus, uncus, temporal pole

22
Q

Part of the brain that has to do with pain

A

Insula lobe

23
Q

What is the middle bend of the internal capsule called?

A

the genu

24
Q

What is anosognosis and what kind of lesion causes this problem?

A

Lack of awareness of disease

Occurs with lesions involving the right parietal lobule

25
Q

Broca’s area vs Wericke’s area problems:

A

Broca’s aphasia: Expressive aphasia - cant form speech

Wernicke’s aphase: Receptive Aphasia - Failure to recognize or comprehend meaning of known words
