A new review article summarizes the wide-ranging, evolving potential of devices that modulate vagus nerve activity.

WHEN nerve impulses bring about the development of tension in a muscle, depolarization of the muscle fibre membranes can be observed. The question arises: Is this depolarization directly responsible ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...
