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 ...

Researchers have used new imaging techniques to explore the function and structures of the neuro-cutaneous unit, which is the connection between the nervous system and the skin. The results may change ...

Nerve fiber pathways Nerve fiber tracts in three brain regions, color-coded. The scattering polarimeter combines the measured fiber directions of ComSLI and 3D-PLI (right), resulting in a better ...

Axons that are regularly stimulated do not pass on increases in performance to their neighbors, study on mice reveals. A complex network of nerve fibers and synapses in the brain is responsible for ...

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 ...

Christopher Oseh, MD, is a trained primary care physician leveraging almost a decade of clinical experience managing and counseling patients toward better health through positive lifestyle changes. He ...

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 ...
