Fentanyl’s powerful pull comes from both the potent, rapid euphoria people feel while on the drug and the devastating symptoms of withdrawal. Researchers have now zeroed in on brain circuits ...

Fear memories can form in the brain following exposure to threatening situations such as natural disasters, accidents, or violence. When these memories become excessive or distorted, they can lead to ...

Stress worsens sleep quality and can impair memory. Shinjae Chung, from the University of Pennsylvania, led a study to explore a neural pathway in male mice that stress may influence to cause sleep ...

Researchers at University of Tsukuba have identified a previously uncharacterized neural circuit that directly links emotional processing to arousal. In the pathway, GABAergic neurons in the bed ...

Scientists from Duke-NUS Medical School and the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) have discovered a novel pathway to wake up dormant neural stem cells, ...

Stanford Medicine investigators have replicated, in a lab dish, one of the most prominent human nervous pathways for sensing pain. This nerve circuit transmits sensations from the body’s skin to the ...

Because unpleasant withdrawal symptoms fuel nicotine addiction’s high relapse rate, targeting their underlying mechanisms with treatments may promote continued abstinence from the drug. In a new ...

Researchers have uncovered a neural pathway preferentially involved in pain perception across species. The study was led by Profs. Tu Yiheng and Hu Li from the Institute of Psychology of the Chinese ...

For the first time, scientists have generated a functional neural pathway for sensing pain in a dish. This could help unravel mechanisms of pain disorders. “This is important groundbreaking work,” ...
