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 ...

This produces light intensity profiles that reveal the underlying brain tissue structure and thus the crossing of nerve fibers. A combination of both methods in a single device would offer decisive ...

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 endurance athletes, some brain power may come from an unexpected source. Marathon runners appear to rely on myelin, the fatty tissue bundled around nerve fibers, for energy during a race, ...

Developed by Stanford researchers, NeuroString is a hair-thin multichannel biosensor and stimulator with promising potential applications in drug delivery, nerve stimulation, smart fabrics, and more.

Language processing in humans depends on the neuronal connection between language areas in the brain. Until recently, this language network was thought to be uniquely human. Now, in a discovery ...

The obturator nerve is a large, multibranched nerve that travels through your pelvis to your inner thigh. This nerve helps you feel sensations like temperature and pain in your lower limbs. It also ...

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 ...

Small fiber sensory neuropathy is a neuromuscular disorder that affects millions of people. It can be caused by various conditions, such as diabetes or prediabetes. It can also occur on its own. Main ...

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 ...
