Which of the following statements concerning synaptic transmission is correct?

#SCPH28 | Zoology
  1. When a specific population of synaptic terminals is spread over the considerable surface of a neuron, their collective effects cannot spatially summate and lead to initiation of an action potential
  2. Even if the successive discharges of an excitatory synapse occur sufficiently close in time, they cannot temporally summate and initiate an action potential
  3. A neuron is “facilitated” when its membrane potential is moved in the less negative or depolarizing direction
  4. Even when rapidly stimulated by excitatory synaptic input for a prolonged period of time, neurons typically do not exhibit synaptic fatigue
