Neurodegenerative conditions such as Parkinson's disease and Alzheimer's involve progressive neuronal loss due to ...

1 Neurons are composed of a cell body containing the nucleus, dendrites that receive chemical, electrical, or other signals via receptors or through gap junctions (direct connections between two ...

Myelinated axons are present in sensory neurons and motor neurons, but not all sensory and motor neurons are myelinated. Most neurons that carry signals regarding movement and higher-level ...

pearled axons showed faster action potentials when sodium channels were periodically spaced at 190nm. Next, the researchers tested the neurons’ ability to conduct electrical signals in mouse neurons.

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 ...

The folding brain creates a stress landscape, causing axons – the long, slender projections of neurons that transmit ...

While most of the brain’s neurons are thought to be created before birth, an explosion in neural connections, the myelination of axons, and other developments boost its total volume. Research ...

New structural markers of memory storage uncovered by Scripps Research may pave the way for new treatments for memory loss.

By influencing calcium homeostasis, local protein synthesis and the endoplasmic reticulum, a small protein called Rab10 emerges as a crucial cytoplasmic regulator of neuropeptide secretion.

The growth cones aid in the extension of the neuron’s axon. They also detect chemicals in the surrounding environment that help guide the neurons’ projections to the appropriate targets. In mice, ...

Eleven foals in the Pacific Northwest were diagnosed with a condition called Equine Juvenile Spinocerebellar Ataxia (EJSCA).
