Question 1

When more action potentials arrive at the axon terminal, how are neurotransmitters affected?
◦ Different molecules are released into the synapse.
◦ More molecules are released into the synapse.
◦ Fewer molecules are released into the synapse.
◦ There is no effect–all signals are identical.

Question 2

When more action potentials arrive at the axon terminal, how is a postsynaptic neuron affected?
◦ Neurotransmitter release increases, but does not change the graded potentials in postsynaptic neurons.
◦ Neurotransmitter release increases, increasing the frequency or magnitude of graded potentials in the postsynaptic neuron.
◦ Neurotransmitter release does not change, but voltages in the postsynaptic neuron increase.
◦ Neurotransmitter release does not change, and the postsynaptic neuron behaves the same way it always behaves.
