Answer 1

The processing, storage and retrieval of information acquired through learning.

Question 2

Define Memory Trace.

Answer 2

A physical trace of the information in the brain.

Question 3

Define Neural Plasticity.

Answer 3

The ability of the brain’s neural structure or function to be changed by experience throughout the lifespan.

Question 4

Define Developmental Plasticity.

Answer 4

Changes in the brains neural structure in response to experience during its growth and development.

Question 5

Define Adaptive Plasticity.

Answer 5

Changes occurring in the brains neural structure.

Question 6

List the 3 functions of Adaptive Plasticity.

Answer 6

1. To enable adjustment to experience.
2. To compensate for lost function.
3. Maximise remaining functions in the event of brain damage.

Question 7

A relatively permanent change in behaviour that occurs as a a result of experience.

Question 8

Define Synaptic Plasticity.

Answer 8

The ability of the synapse to change over time.

Question 9

List the 3 ways in which synapse strength can increase.

Answer 9

1. Release extra neurotransmitter.
2. Increase number of receptor sites.
3. Growth of new synapses.

Question 10

Define Long-Term Potentiation.

Answer 10

Refers to the long-lasting strengthening of synaptic connections, resulting in enhanced or more effective synaptic transmission.

Question 11

Define Long-Term Depression.

Answer 11

Refers to the long-lasting decrease in the strength of synaptic transmission which results in a weakened synaptic transmission.
