A) The reuptake of norepinephrine and serotonin are blocked; larger amounts of norepinephrine and serotonin are released,and there is less neuronal firing.
B) The reuptake of norepinephrine and serotonin are blocked,norepinephrine or serotonin remains in the synapse longer; and there is increased stimulation of receiving neurons.
C) There is less neuronal firing; more norepinephrine and serotonin are released; and reuptake slows release of norepinephrine and serotonin.
D) Norepinephrine and serotonin are blocked; neurons cease firing briefly; and neurons begin firing without norepinephrine and serotonin.
