Researchers have identified connections between neurons in brain systems associated with reward, stress, and emotion. Conducted in mice, the new study may help untangle multiple psychiatric conditions, including alcohol use disorder, anxiety disorders, insomnia, and depression in humans.
Understanding these intricate brain systems will be critical for developing diagnostic and therapeutic tools for a broad array of conditions. The National Institute of Mental Health (NIMH) also provided major support for the research. NIAAA and NIMH are parts of the National Institutes of Health. The study was published in Nature Neuroscience.
