1

What are the three components of the brainstem in order?

Midbrain, Pons, Medulla

2

What does the cerebellum take part in?

Coordination of movement

3

What are the three components that make up the hind brain?

Cerebellum, medulla, pons

4

What are the folds of the brain called?

Gyrus/gyri

5

What are the gaps between folds of the brain called?

Sulci

6

What are the folds made up of?

Grey matter 6-7 mm thick with a layer of white matter underneath.

7

What are the 3 key sulci?

Central sulcus, parieto-occipital sulcus, lateral sulcus (fissure)

8

What is the name of the important notch in the brain?

Preoccipital notch

9

What does the central sulcus separate?

Frontal and parietal lobe

10

What are the four gyri of the frontal lobe?

Superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus, precentral gyrus

11

What lies beneath the lateral fissure?

Temporal lobe

12

What are the three longitudinal gyri of the temporal lobe?

Superior, middle and inferior temporal gyrus

13

What is behind the temporal lobe?

Occipital lobe

14

What lobe lies between the frontal, occipital and temporal lobe?

Parietal lobe

15

What is the name of the sulcus which separates the parietal lobe into an upper and lower part?

Intraparietal sulcus

16

What is the parietal lobe split into?

Superior and inferior parietal lobule

17

What are the names of the two gyri found on the inferior parietal lobule? What is special about them?

Supramarginal gyrus and angular gyrus. They are connected to form an m shape.

18

What is the other singular gyrus of the parietal lobe?

Postcentral gyrus

19

What does the precentral gyrus correspond with? What does it control?

Primary motor cortex. Controls muscles on the other side of the body.

20

What is the primary motor cortex dominated by?

The face and hands

21

What is meant by somatotopical?

Organised by body region. Increasing complexity requires more brain cells and a larger region of the cortex.

22

What is meant by primary and motor of primary motor cortex?

Primary: critical role
Motor: movement

23

What does the postcentral gyrus correspond with? What is it involved with?

Primary somatosensory cortex. Where you consciously appreciate every touch on your skin.

24

Large areas of the primary somatosensory cortex are devoted to ________ ____________ regions of the body.

Highly discriminatory

25

What is the purpose of the primary visual cortex?

Allows you to see the world.

26

What surrounds the primary visual cortex?

The calcarine sulcus

27

How is the primary visual cortex organised?

Visuotopically organised (retinotopically)

28

Why don't we see a line down the middle of the world?

Visual cortex on one side communicates with the visual cortex on the other.

29

What do the areas around the primary visual cortex do? What are they called?

Add value (shape and colour) to the original picture.
Supplementary/secondary visual cortices

30

From where does the primary auditory area get input from?

Gets input from the ear on the opposite side.
