Fragmented sleep, he found, led to severe impairments the next day in pain pathways.

In rare cases, surgery may be done to destroy a nerve or nerves that are part of the pain pathway.

It may also block other pain pathways in the brain.

One can also use nociception assays to assess the physiology of the "pain" pathways.

Thus, there is cross talk between the two pain pathways.

Besides just a simple distraction, music may also have acupuncture-like effects at interrupting pain pathways, he says.

Impulses generated in nociceptors follow classic 'pain pathways' to consciousness.

Impulses are generated as a result of neural dysfunction and do not follow classic pain pathways.

The mirror may have provided visual feedback that turned down the brain's pain pathways, suggest the researchers, who don't know exactly how that process works.

Once they are out of commission, the pain pathway up the spinal cord is permanently activated.
