Muscle synergies represent coordinated activation patterns of groups of muscles that simplify the control of complex movements. This concept suggests that the central nervous system reduces the ...

Motor neurons play a vital role in movement, linking the central nervous system with different muscles in the body. As such, scientists are very interested in understanding the biological mechanisms ...

MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...

A research team has developed an "intelligent artificial muscle" capable of simultaneously performing sensing and actuation ...

The seemingly simple act of reaching for a cup of coffee requires a lot of effort from the brain. It has to plan a trajectory to the cup, control dozens of muscles, make adjustments based on feedback ...

The hypoglossal nerve is one of the 12 cranial nerves arising from the brain. It's a paired nerve, and you have two — left and right. Together, the two hypoglossal nerves control the muscles of the ...

Spontaneous muscle twitching can be an early symptom of ALS and a sign that motor neurons are damaged. But other causes can also contribute to muscle twitching. Consulting a doctor can help identify ...

It’s a bizarre sight: With a short burst of light, a sponge-shaped robot scoots across a tiled surface. Flipped on its back, it repeatedly twitches as if doing sit-ups. By tinkering with the light’s ...

Motor neurons play a vital role in movement, linking the central nervous system with different muscles in the body. A new study has uncovered details about the process through which motor neurons ...
