Functional Connectivity of the Default Mode Network During Opioid Use and Cessation Background Opioid abuse has become a global public health issue, particularly in the United States, where opioid overdose deaths have tripled since 1999. Opioids not only lead to addiction but are also associated with chronic pain, immune system suppression, and neu...
