Karen Cropsey, Psy.D., and Karen Gamble, Ph.D., professors in the Department of Psychiatry and Behavioral Neurobiology, have received a new grant totaling $4.4 million over a 4-year period to support their study “Medications for opioid use disorder differentially modulate intrinsically photosensitive retinal ganglion cell function, sleep, and circadian rhythms: implications for treatment.”
This study investigates why individuals with opioid use disorder, who are maintained on opioids for treatment, often suffer from poor sleep. While the connection between opioid use and sleep problems is well-known, the underlying biological mechanisms remain unclear.
