The ultrathin tendrils that zip messages around the nervous system are often drawn as smooth ... nerve fibers called axons may actually be a series of bumps, researchers suggest December 2 in ...

They have some features in common: A long fibre (axon) which is insulated by a ... as electrical impulses to co-ordinators such as the central nervous system or CNS. The CNS is the brain and ...

Dr. Rasband's team is discovering the functional organization of axons in health as well as disease or injury. The generation, propagation, and modulation of electrical signals in the nervous system ...

But neurons are not alone in the brain or elsewhere in the nervous system: Brain cells called glia play various supporting roles to keep the system running smoothly. Between the axon of a ...

This important study leverages the power of Drosophila genetics and sparsely-labeled neurons to propose a new model for neuronal injury signaling. The authors present convincing evidence to support ...

Dec. 18, 2024 — Dancing lowers the depression associated with Parkinson's disease, and the benefits can be seen in multiple ways, a new study ...

The bioenergetic deficits observed in Amyotrophic Lateral Sclerosis result from the disruption of mitochondria-associated ER membranes. Here, the authors show that this disruption impairs the use ...

Recognizing serious symptoms can help you get the treatment you need. The term "nervous breakdown" originated during the 1700s, when scientists believed our nervous system caused mental health ...

Biochemial, transcriptional and histological measurements in spinal cord supported that these gait improvements reflected increased axon survival, remyelination ... The company is planning to develop ...

They serve as survival factors to ensure a match between the number of surviving neurons and the requirement for appropriate target innervation and also regulate cell fate decisions, axon growth, ...
