NEURO/SYNAPTIC PLASTICITY - LTP LTD etc

Question 1

what is neuroplasticity?

Answer 1

the ability for the brain to change in response to experience

Question 2

what is synapticplasticity?

Answer 2

the ability of synaptic connections to change over-time in response to an activity or experience
(the process name for neuroplasticity)

Question 3

what are the 2 types of neuroplasticity?

Answer 3

developmental: naturally across the lifespan
adaptive: occurs as a result of brain damage or trauma

Question 4

LONG-TERM POTENTIATION (LTP) ?

Answer 4

refers to long-lasting strengthening of synaptic connections
: resulting in enhanced or more effections synaptic transmission
(bushier dendrites : sprouting)

Question 5

LONG-TERM DEPRESSION (LTD) ?

Answer 5

refers to long-lasting decrease in strength of synaptic transmission
occurs there is a lack of stimulation between pre and post-synaptic
(elimination of unused dendrite branches : pruning)

Question 6

SPROUTING?

Answer 6

the growth of new dendrites branches
: occurs when there is repeated activation of neuron

Question 7

PRUNING?

Answer 7

elimination of unused dendrite branches
: occurs when there is low level activation of neuron

Question 8

REROUTING?

Answer 8

the developmental of neural pathways to cater for change/loss of neurons due to DAMAGE (damage/trauma)
