A computer screen shows the electrical activity of a specialized heart cell called a sinoatrial nodal cell. This type of cell can beat on its own without electrical stimulation, allowing scientist to see its activity when extracted. Information gleaned is contributing to understanding heart-pacing changes that occur during the body's "fight or flight" response to stress.
