True or False: Cells receive input from multiple sources coming onto the cell body
and dendrites.
ANS:
✓ True.
What are 2 ways that one can change the properties of neurotransmission (forms
of neuroplasticity)?
ANS:
✓ 1. Change in neurotransmitter release
✓ 2. Change in the size or shape of the post-synaptic potential

✓ 1. Changing size or shape of cell
✓ 2. Changing electrical properties (resistance)
✓ 3. Changing the leakiness of the membrane
What are the 3 overarching forms of neuroplasticity?
ANS:
✓ 1. Change the properties of neurotransmission
✓ 2. Change cell properties
✓ 3. Structural/anatomical changes in cells
True or False: the bulk of the (neuroplasticity) changes that we see in rehab are a
result of structural or anatomical changes in cells.
ANS:
✓ False. (This form of neuroplasticity takes a lot of time, and this is not
the bulk of change that we will be seeing in rehab)
Unmasking is an example of which form of neuroplasticity?
a) Change the properties of neurotransmission
b) Change cell properties
c) Structural/anatomical changes in cells
