U3 AOS1 Synaptic plasticity

Question 1

Synaptic
plasticity

Answer 1

specific changes
that occur within
the synapse,
between neurons

Question 2

Long-term
potentiation (LTP)

Answer 2

the relatively
permanent
strengthening
of synaptic
connections
as a result
of repeated
activation of a
neural pathway

Question 3

Long-term
depression (LTD)

Answer 3

the relatively
permanent
weakening
of synaptic
connections
as a result of
repeated low level activation

Question 4

Sprouting

Answer 4

the growth of
axon or dendrite
fibres at the
synapse

Question 5

Dendritic spine

Answer 5

a dendrite fibre
that grows by
sprouting on the
post-synaptic
neuron

Question 6

Filigree
appendage

Answer 6

a fibre that
grows by
sprouting
from the axon
terminal of the
presynaptic
neuron

Question 7

Synaptogenesis

Answer 7

the formation of
new synapses
that result from
the process of
sprouting

Question 8

Rerouting

Answer 8

the formation of
new connections
between neurons
to establish
alternative
neural pathways

Question 9

Pruning

Answer 9

the removal of
excess neurons
and synaptic
connections
to increase
the efficiency
of neuronal
transmissions
