1

In what sub-cortices can the cerebral cortex be divided?

Neocortex
Archicortex
Paleocortex

2

Two other names for neocortex?

Neopallium or
Isocortex.

3

The Archicortex and the Paleocortex are the cortical parts of what system?

The limbic system.

4

What is white matter?

Glial Cells
Myelinated Axons

Fun Fact for Cannibals: freshly cut white matter actually appears pinkish and becomes white due to preservation in formaldehyde.

5

What does grey matter consist of?

Neuronal Cell Bodies
Neuropil (dendrites and unmyelinated axons)
Glial Cells
Capillaries (a body's smallest blood vessels)

6

How many horizontal layers does the neocortex consist of?

6

7

What does a gyrus look like?

a wrinkle

8

What does a sulcus look like?

a groove

9

Why is the neocortex also called isocortex?

Because its structure is relatively uniform -> iso

10

Which lobes are part of the neocortex?

All (frontal, temporal, parietal and occipital) but the insular lobe.

11

What are the two parts of an insular lobe (aka.: insular cortex, insulary cortex, insula or the "Island of Reil")?

the anterior insula (larger)
the posterior insula (smaller)

12

What sulcus lies between the temporal and the frontal lobe?

the lateral sulcus (aka. lateral fissure)

13

What are the names of the three gyri comprising the superolateral temporal lobe (from top to bottom)?

Superior Temporal Gyrus
Middle Temporal Gyrus
Inferior Temporal Gyrus
(Note: Middle not medial!)

14

What's the name of the sulcus that seperates frontal and parietal lobe?

central sulcus

15

What gyri comprise the superolateral frontal lobe (from top to bottom and then going backwards?

Superior Frontal Gyrus
Middle Frontal Gyrus
Inferior Frontal Gyrus
Anterior Central Gyrus

16

The post central gyrus is part of which neocortical lobe?

the parietal lobe

17

Latin for front,
back and
sidewards?

anterior
posterior
lateral

18

Latin for in the middle?

medial

19

What is the name of the "lid" covering the insular lobe and consisting of three other lobes?

Operculum

20

That part of the frontal/occipital/parietal/temporal lobe that lies on the surface?

superolateral

21

Fancy adjective for example for internal parts of lobes?

medial

22

Fancy adjective for the fordermost part of the frontal lobe?

prefrontal

23

On the basis of what are Brodmann areas distinguishable?

on the basis of Cytoarchitectonics (cell-architecture)

24

The olfactory bulb lies inferior to?

the frontal lobe

25

Where is Broca's area located?

(only!) on the left (!) inferior frontal gyrus

26

Where is Wernicke's area located?

on the superior temporal gyrus

27

Two possible kinds of somatic nerves?

sensory nerves
motor nerves

28

There are somatic nerves and ______ nerves.

vegetative nerves

29

groups of nerve cells are connected by?

tracts (pathways)
