Synaptic plasticity

Question 1

synaptic plasticity

Answer 1

connections between neurons to change and adapt - how our brain learns and forms memories

Question 2

Mechanisms of synaptic plasticity

Answer 2

1.sprouting
2.reruiting
3.pruning

Question 3

Mechanisms of synaptic plasticity: sprouting

Answer 3

ability of dendrites or axons to develop new extensions or branches

Question 4

Mechanisms of synaptic plasticity: rerouting

Answer 4

a neuron that is connected to a damaged neuron to create an alternative synaptic connection with an undamaged neuron

Question 5

Mechanisms of synaptic plasticity: pruning

Answer 5

the elimination of synaptic connections that are not adequately activated

Question 6

Long-term potentiation (LTP) (sprouting)

Answer 6

long-lasting enhancement of synaptic transmission due to repeated strong stimulation - memory

Question 7

long term potentiation example

Answer 7

1. neurons involved in bike riding r coactivated, continueing practicing will allow these neurons to be repeatedly coactivated
2. synaptic connections between these neurons physically change - strengthening
   3.memory trace forms

Question 8

LONG TERM DEPRESSION (LTD)
(pruning)

Answer 8

long-lasting decrease in the strength of synaptic transmission and neuronal response

Question 9

LTD OCCURS…

Answer 9

due to repeated low level stimulation of a presynaptic and a postsynaptic neuron.

Question 10

similarities between LTD n LTP

Answer 10

both have long lasting effects, both occur at glutamate synapses
