To make a working nervous system, only two forces are necessary: excitation and inhibition. Excitatory signaling from one cell to the next makes the latter cell more likely to fire. Inhibitory ...

Dr. Myerburg answers the question: 'What Is Pre-Excitation, Is It Dangerous?' — -- Question: On a routine EKG I was diagnosed to have pre-excitation. What is that and is it dangerous?

The exceptionally low 8 eV excitation energy corresponds to light in the vacuum ultraviolet, which can be generated by a laser. As a result, the transition could be used to create an accurate clock.

The Excitation Emission Matrix (EEM) is a specific measurement that is becoming more and more respected and widely used within the field of fluorescence spectroscopy. An EEM is essentially a three ...
