A new study found that aged neurons have defects in key proteins that make them vulnerable to molecular stress and neurodegenerative damage.

Discover how neurodegenerative diseases may start with blood-brain barrier damage, leading to memory loss and cognitive ...

Neuropathy, a disorder in which damage to nerves can impair sensation and movement, has many causes, including infection. Now ...

Is there a difference in brain structure between men and women? If we were to find such a difference in a single neuron, would it matter? One of the most useful models for studying these questions ...

Mitochondria Are More Than Powerhouses—They’re the Motherboard of the Cell ...

The study, "Supramolecular copolymerization of glycopeptide amphiphiles and amyloid peptides improves neuron survival," was published in the Journal of the American Chemical Society. "Our study ...

My search for answers to these stupendously ambitious questions led me, it now seems inexorably, to mitochondria. This idea of mitochondria being little batteries with a built-in charger, about as ...

Mitochondria take up around 40% of the cytoplasm in heart muscle cells. Although pictures often depict mitochondria as oval-shaped organelles, they constantly divide (fission) and bond together ...

These signals are called nerve impulses, and they’re generated by changes to the electrical charge of the nerve cell membrane. The changes occur due to the movement of the electrolyte sodium ...

Learning takes place at the synapses – those are the locations at which the electric signals are relayed from one nerve cell to another. Neuroscientists have discovered that synapses can vary the ...
