Microscopic spines connect worm neurons

Dendritic "spines"—small protrusions on the receiving side of the connection (synapse) between two nerve cells—are recognized as key functional components of neuronal circuits in mammals. The shapes and numbers of spines ...

Growing a smarter model for brain research in space

Researchers studying neurological diseases face several daunting challenges. For one thing, these conditions may take years or even decades to develop. On top of that, experimenting on the brains of healthy human beings simply ...

Why your foot calluses might be good for you

Before you take a pumice stone to your foot calluses just because they're unsightly, you might want to consider the idea that they are actually nature's shoes.

Frog protein may mitigate dangers posed by toxic marine microbes

A new study from UC San Francisco suggests that a protein found in the common bullfrog may one day be used to detect and neutralize a poisonous compound produced by red tides and other harmful algal blooms. The discovery ...

Nerve

A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous system. In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is technically inaccurate since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.
