In a study, scientists challenge a fundamental tenet in neuroscience about the shape of axons -- the long, thin filaments radiating from nerve cells that transmit electrical signals from cell to cell ...
A biodegradable ionic hydrogel battery modeled on electric eel organs powers a nerve conduit that accelerates peripheral nerve regeneration without external energy.
The ultrathin tendrils that zip messages around the nervous system are often drawn as smooth lines. But a new study adds some flourishes to that classical picture. Like a garland of cranberries hung ...
How do the nerve cells in our brain communicate with each other? What processes take place when T cells render cancer cells harmless? Details of the mechanisms at the cellular level remain hidden from ...
A tickly itch, a painful scratch, or the feeling of a refreshing breeze—the skin is teaming with nerve endings that drive these sensations. Scientists are getting into the epidermis to explore how ...
It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...
The wiring of one insect’s brain no longer contains much uncharted territory. All of the nerve cells — and virtually every connection between them — in a larval fruit fly brain have now been mapped, ...
Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...
