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 ...

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 ...

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 ...

In the split second that is needed to view a stop sign and react to it, our brain navigates a complex process that transitions seamlessly from perception to action control. This ability to halt or ...

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

The brain's ability to adapt and form new neural connections allows it to recover from injury and maintain cognitive function into old age. Neuroplasticity is the brain's ability to adapt 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,” ...
