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

A tickly itch, a painful scratch, or the feeling of a refreshing breeze—the skin is teaming with nerve endings that drive these sensations. Scientists are getting into the epidermis to explore how ...

Microscopic cross-section through a peripheral nerve bundle (dark blue), which contains hundreds of nerve fibers coated with Schwann cells. Numerous large fat cells (light blue) can be seen in the ...

The vagus nerve is a vine of nerve fibers with roots in nearly every organ and shoots in the brain. It helps us detect a racing heart, rising blood pressure, stomachache, discomfort, an overzealous ...

Researchers have uncovered that tinnitus, an incurable persistent ringing or other sounds in the ears, might result from underlying auditory nerve damage that can't be detected on conventional hearing ...

Cross-section of nerve fibers from the mouse optic nerve: The dark dense lines show the insulating layer, the myelin. Highlighted in red is a swollen, clogged area of an impaired nerve fiber – caused ...
