Neural Basis of Learning

Question 1

Define learning

Answer 1

a relatively permanent change in behaviour that occurs through experience involving the acquisition of skills or knowledge

Question 2

define • Memory

Answer 2

recalling & expressing what knowledge you have acquired

Question 3

define • Neural Plasticity

Answer 3

ability to modify neural structure & function changed through experience in the brain (brain as a whole)

Question 4

Define Synaptic Plasticity

Answer 4

ability of the synapse to change over time

Question 5

Define • Long Term Potentiation (LTP)

Answer 5

strengthening of the synaptic connections, enhancing synaptic transmission

Question 6

Define • Long Term Depression (LTD)

Answer 6

decrease in strength of synaptic transmission as a result of lowered stimulation between neurons
(Neurons that fire apart wire apart )

Question 7

Define • Consolidation

Answer 7

process of making newly formed memories stable

• Takes 30 mins to ‘to set’

Question 8

If consolidaiton is disrupted, how much time of memories is lost

Answer 8

If disrupted, then last 30 mins are lost (e.g. concussion)

Question 9

How is consolidation enhanced

Answer 9

• Enhanced by adrenaline & noradrenaline

Question 10

Define • Neurohormones

Answer 10

Chemical messengers, manufactured by neurons, released from axon terminals

Question 11

What is • Glutamate’s role in LTP/LTD

Answer 11

• Glutamate promotes growth & strengthens synaptic connections (LTP)
