Clinical Significance
Since the mesolimbic pathway is shown to be associated with feelings of reward and desire, this pathway is heavily implicated in neurobiological theories of addiction, schizophrenia, and depression. Drug addiction, the loss of control over drug use or the compulsive seeking and taking of drugs despite adverse consequences, with the four major classes of abused drugs (psychostimulants, opiates, ethanol, and nicotine) are due to increased dopamine transmission in the limbic system-each by different mechanisms. Like drug addiction, schizophrenia and depression have similar structural changes with dopamine transmission.

Famous quotes containing the word significance:
“For a parent, it’s hard to recognize the significance of your work when you’re immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, “I’m making my contribution to the future of the planet.” But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
