3: KKDP 1: Neural Plasticity

Question 1

Learning v Memory:

Answer 1

Learning is the acquisition of a skill or knowledge. Memory is the expression of what you have acquired.

Question 2

Neural Plasticity:

Answer 2

Refers to the way the brain changes in response to stimulation from the environment.

Question 3

Neural Plasticity (2)

Answer 3

The brain is capable of learning because of its flexibility in being able to adjust to changes in enviromental input.

Question 4

Synaptic Plasticity:

Answer 4

Refers to the ability of the synapse to change over time. Our brain constantly modifies its neural connections and pathways, resulting in a structure constantally remodelled by experience.

Question 5

Long-Term Potentiation:

Answer 5

The long lasting strengthening of synaptic connections resulting in the enhanced functioning of neural pathways.

Question 6

Long-Term Depression:

Answer 6

The long lasting decrease in the strength of synaptic transmission.

Question 7

Difference 1 (Feature):

Answer 7

LTP - Improvement in overall communication between neurons

LTD - Weakening of communication between neurons

Question 8

Difference 2 (Process):

Answer 8

LTP- Results from repeated stimulation of a neural pathway

LTD - Results from a lack of stimulation of a neural pathway

Question 9

Difference 3 (Purpose):

Answer 9

LTP - Decreases the likelihood of forgetting memories

LTD - Increases the likelihood of forgetting memories

Question 10

Difference 4 (Purpose):

Answer 10

LTP - Allows us to strengthen important memories

LTD - Allows us to eliminate unimportant memories

Question 11

Hebbs Rule:

Answer 11

‘Neurons that wire together fire together’

Question 12

Synaptogenisis:

Answer 12

Growing new synapses.
