Cellular machinery that enables neurons to fireIf you ever had a set of Micronauts toy robots with removable body parts you probably had fun swapping their heads, imagining how it would affect their behavior. Researchers supported by the National Institutes of Health have been performing similar experiments on ion channels pores in our nerve cells to sort out the channels' key functional parts.
