If one measures the voltage potential of a presynaptic neuron and a postsynaptic neuron that form a synapse,
 
  the magnitude of the potential measured at the postsynaptic membrane is typically ___________________ ___ the potential measured at the presynaptic membrane when an action potential arrives at the presynaptic neuron's axon terminal.
  a. larger than b. smaller than c. equal to

Question 2

When chemically (ligand) gated channels open and allow negatively charged ions (e.g., chloride, Cl-) to enter a neuron in the dendrites or cell body, the consequence is
 
  a. a decrease in the neuron's excitability (i.e., its tendency to create an action potential)
  b. an increase in the neuron's excitability (i.e., its tendency to create an action potential)
  c. to create an action potential
