For treatment of ADHD (attention deficit hyperactivity disorder), tricyclic antidepressants are often prescribed. These drugs act by affecting the reuptake of neurotransmitters. What effects does this have on the postsynaptic neuron? (Assume an excitatory neurotransmitter.)

Tricyclic antidepressants, such as imipramine hydrochloride, work by allowing the excitatory neurotransmitters to remain in the synaptic cleft for longer periods of time. Because the neurotransmitters are present for longer periods of time, they increase the number of successive action potentials generated by the postsynaptic neuron.
