1

What is habituation?

Decrease in response to repeat benign stimulus

2

What is sensitization?

Strengthening of responses to a wide variety of stimuli following an intense or noxious stimuli

3

T/F Sensitization overrides effects of habituation

True

4

Imitative learning is important in what?

Acquisition of language

5

What type of neurons are part of imitative learning?

Mirror neurons

6

Mirror neurons are cortical neurons that fire when what?

When we observe somebody doing something that helps us relate to what they are doing and perhaps is important in our acquiring those motor skills

7

The cortical mirror neuron system is formed by what two main regions?

Ventral premotor cortex and rostral part of the inferior parietal lobule

8

What type of conditioning involves a learning relationship between two stimuli

Classical conditioning

9

Operant conditioning is a learning relationship between what?

Stimulus and organism behavior

10

Classical conditioning is a pairing of what two stimuli to condition response?

Conditioned and unconditioned

11

Formation of a predictive relationship between a response and a stimulus is what type of conditioning?

Operant conditioning

12

Animals and people learn to predict the consequences of their own behavior in what type of conditioning?

Operant

13

Biofeedback is a form of which conditioning?

Operant

14

T/F The number of neurons and their connectivities stay the same during learning

False; they change significantly

15

If neurons do not make meaningful connections they will ___

Perish

16

Neuron connections are determined by what?

Nerve growth factors released retrogradely from + cells

17

Soon after birth, many areas of the cerebral cortex may lose what percentage of original neurons

50% or more

18

What causes the loss of original neurons?

Nonuse

19

T/F In adults there is modification in the number of neurons and their connections

True

20

What is represented in multiple regions throughout the nervous system

Long term memory

21

Storage of memory is associated with what structural changes in synapes?

Increase in: transmitter vesicles, release sites for neurotransmitter, number of presynaptic terminals, number of synaptic connections
Changes in structure of dendritic spines

22

Protein kinase M zeta maintains what?

Long term potentiation (LTP) in hippocampal neurons

23

What else is blocked when Protein kinase M zeta is blocked?

Long term memory function

24

Zeta inhibitory peptide (ZIP) blocks _____

PKM zeta

25

Holographic memory uses what type of waves?

Coherent waves

26

What two type of interference patterns are associated with holographoc memory?

Constructive and destructive

27

____ alters human behavior by learning and memory

Environment

28

Process by which we acquire knowledge about the world

Learning

29

Process by which knowledge is encoded, stored, and retrieved

Memory

30

T/F All learning is beneficial

False
