a protein that spans the cell membrane and matches up axons with dendrites to form synapses in the developing brain.

Myelin is a concentrically laminated membrane structure surrounding an axon around which lamellae (or cellular protrusions) repeat radially at a period of about 12 nm (Waxman, Kocsis & Stys 1995 ...

"Understanding the structure of axons is important for understanding brain cell signaling," says Shigeki Watanabe, Ph.D., ...

Their findings, published in Nature Neuroscience, contrast with the classical view of tubular axons. 2 The researchers propose that this shape is a ubiquitous feature in all unmyelinated axons; ...

The permanent neurological deficits of multiple sclerosis patients largely depend on the extent of degeneration of long nerve fibers. The latter is initiated by ruptures in the cell membrane and ...

The scientists named the pearl-like structures in which the axon swells “non-synaptic varicosities.” “These findings challenge a century of understanding about axon structure,” says Watanabe. The ...

Myosin Va and Endoplasmic Reticulum Calcium Channel Complex Regulates Membrane Export during Axon Guidance. Cell Reports , 2016; DOI: 10.1016/j.celrep.2016.04.021 Cite This Page : ...

The findings appear online Jan. 27, 2011 in the journal Neuron.. Our hard-wired nerve fibers or axons rely on an insulating membrane sheath, the myelin, made up of fatty white matter to accelerate ...

Since the early part of the 20th century, scientists have been trying to better understand the intricacies surrounding neuronal development. In particular, the process by which glial cells ...

"Understanding the structure of axons is important for understanding brain cell signaling," says Shigeki Watanabe, Ph.D., associate professor of cell biology and neuroscience at the Johns Hopkins ...
