Action Potential

Question 1

Threshold Potential

Answer 1

the membrane potential at which depolarization becomes self-regenerative, i.e., no additional stimulus is required

Question 2

Depolarization

Answer 2

beginning at the VR, depolarization refers to any change in the Vm that reduces the magnitude of the membrane potential (makes the Vm less negative or more positive)

Question 3

postsynaptic potential

Answer 3

The changes in membrane potential that result from the interaction of a neurotransmitter with a postsynaptic receptor (its a type of local potential)
