When your brain talks, your muscles don't always listen

Have your neurons been shouting at your muscles again? It happens, you know. As we grow older, ...to "speak" more loudly to get the attention of our muscles to move, according to University of Delaware researcher Christopher Knight, an assistant professor i...

Researchers develop marker that identifies energy-producing centers in nerve cells

...ood calories. It is these nerve signals that cause muscles to move and thoughts to be processed. Dr. Chandrasekaran says the fluorescent marker system may make it possible to explore how neuronal activity and the mitochondrial energy-producing system are coordinated and how the interrelationship works. T...

Leeches ferry infection among newts

...nism of the genus Ichthyophonus, which infects the muscles of red-spotted newts and other amphibians in North America. It does not appear to kill amphibians but might affect their ability to reproduce. "This is the first evidence that newts are getting infected through the bites of leeches," said Thomas ...

Fast and slow -- How the spinal cord controls the speed of movement

...ay contribute to activating a system of nerves and muscles that allow for faster movement. They suspect that damage to these brain cells may disrupt the release of dopamine, further complicating free movement. Fetcho and his group are building a transgenic line of fish with those brain cells labeled so they ...

The basic hypothesis of the project was that the organ of balance -- which helps stabilize an animal's gaze and coordinate its movements as it travels through the environment -- should be irrevocably ...

Runners -- Let thirst be your guide
