Antidepressant drugs have similar effects on serotonin and norepinephrine neurons.
Our experiments focus on the chronic effects of cocaine and antidepressant drugs on the neurons. Shown at right is a coronal section through the upper brain stem of a human brain. In the center is the substantia nigra where dopamine cell bodies are located. The dark staining results from the deposition of melanin and marks dopaminergic cell bodies. Springer-Verlag Wien, 1991.
