✓ the level of stimulation required to trigger a neural impulse
Neuroplasticity
ANS:
✓ multiple processes and multiple opportunities for neurone to change
their behaviour
3 ways neuroplasticity occurs
ANS:
✓ 1. change the properties of neurotransmission
✓ - change in transmitter release
✓ - change in PSP size or shape
✓ 2. change in cell properties
✓ - size and shape
✓ - electrical properties (resistance)
✓ - "leakiness" of membrane
✓ 3. structural/anatomical changes of cell
unmasking
ANS:
✓ the exposure of silent synapses

unmasking steps
ANS:
✓ 1. cell responds to dominant input
✓ 2. injury or disease occurs
✓ 3. non-dominant input is expressed
dendritic pruning
ANS:
✓ removal of connections that are no longer needed or incorrect
dendritic pruning steps
ANS:
✓ 1. loss of input to the neuron
✓ 2. dendrites retract

5.0
ANS:
✓ 1. no input to neuron
✓ 2. dendrites start to retract
✓ 3. healthy nerve in the area sends out new inputs
✓ 4. form new connections on the dendrites
activity dependent
ANS:
✓ a property of neural plasticity such that changes in a neuron's
functioning will occur only if that neuron is active (firing) at the same
time as another neuron
neurogenesis
ANS:
✓ the development of new neurons
neurogenesis locations
ANS:
✓ 1. sub ventricular zone (olfactory bulb)
✓ 2. dente gyrus of hippocampus
