Neuroscientists find that two distinct neural pathways are responsible for the addictive properties of the opioid fentanyl: one mediates reward, the other promotes the seeking of relief from symptoms ...

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 ...

An Adelaide-based research collaboration has identified the specific nerve pathways responsible for relaying pain signals ...

The brain of humans and other animals is known to contribute to the protection of the body from infections. Past studies have ...

In a recent review published in the journal Current Biology, researchers examined the origins, mechanisms, and significance of interoception (the sensing and processing of internal bodily states) and ...

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,” ...

The human brain is a marvel, with intricate pathways connecting its various regions — a superhighway of learning. These neural pathways are the foundation of our thoughts, actions and responses to the ...
