To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical signals of active ...

In mice, blocking heart-to-brain signals improved healing after a heart attack, hinting at new targets for cardiac therapy.

Researchers discovered a feedback loop between nerve cells, the immune system and the heart. They think it shows promise as a ...

Dear Doctors: I keep reading about how the vagus nerve has a lot to do with things like mood, digestion and keeping your brain healthy. Where is it located? Supposedly there is even a kind of ...

What situations make you feel nervous, fearful, or anxious to the point that you get butterflies and feel sick to your stomach? Are there people, places, or situations in your life that evoke a ...

Scientists at the University of Gothenburg have pinpointed a group of nerve cells in the brain stem that appear to be responsible for semaglutide’s appetite- and weight-controlling powers—without ...

Nerve fibres in the brain could produce pairs of particles linked by quantum entanglement. If backed by experimental observations, this phenomenon could explain how millions of cells in the brain ...

In order to understand brain diseases, neuroscientists try to untangle the intricate nerve fibre labyrinth of our brain. Before analysing brain tissue under a microscope, it is often soaked in ...

Until recently, most researchers assumed that the vagus nerve sent messages up to the brain from the GI tract using the equivalent of one northbound lane on a gut-to-brain communication superhighway.

After surgery, some older adults don't simply recover—they unravel. Confusion, inattention, and agitation can set in, a condition known as postoperative delirium. For patients already living with ...

A specific group of nerve cells in the brain stem appears to control how semaglutide affects appetite and weight - without causing nausea. The discovery, made at the University of Gothenburg, could ...
