A patient with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which of the following processes will accompany the actions of the neurotransmitter in her chemical synapses?
Question options:
 
More serotonin molecules will cross the synaptic cleft and bond with postsynaptic receptors.
 
The neurotransmitter will cross gap junctions more readily.
 
Communication between a neuron and the single neuron it is connected with will be facilitated.
