1

05 A reductionist approach in neuroscience means

functions become structures at lower biological levels

2

07 The brain has complementary structures organized

Side-to-side

3

08 A coronal section slices the brain

Front-to-back

3

08 A horizontal section slices the brain

Top-to-bottom across the horizontal plane

5

08 A sagittal section slices the brain

Side-to-side

6

15 Cortical gryi are _____ and sulci are _______.

ridges, fissures

7

15 The cortex is ______ thick.

1.5-3 mm

8

15 The cortical surface area is _________.

1000-2000 cm2

9

18 One reason the human species have larger brains adjust for body weight than other species is that

human brain size continues to grow after birth

10

20 Compared to other species human brains proportionally have _____ cells and ______ cell connections.

more, more

11

21 Which cortical region is proportionally larger in human brains than other species?

Associative cortex

12

24 Name the three parts of a neuron's structure?

Soma, dendrite, axon

13

25 A bipolar neuron has

one dendrite and one axon.

14

26 Name some types of glial cells.

Astrocytes

Oligodendrocyte

Microglia

Schwann cell

 

15

27 Neurons communicate by

action potentials

16

28 An action potential lasts a few

milliseconds

17

29 Action potentials cause neurotransmitter

release

18

31 Proliferation, migration, and differentiation are three stages of neural

growth

19

34 Critical periods in behavioral development are associated with neural

differentiation

20

37 Local coding in neurons is most often associated with

primary sensory regions

21

38 A topographical map in the cortex is a _________ representation of the world.

sensory

22

40 One problem with local coding schemes for neurons is that they __________ respond to input.

broadly

23

41 Vector coding schemes for neurons differs from local coding schemes in that representational responses are ___________.

distributed
